I think that one people ought to bring self merit into play to the limit， not only this being helpful to the high limit field excavate own maximal value， and can realizing own social value. My maximal merit depends on assiduity course the close to surveying and mapping remote sense special field for 6 years in Wuhan University studies ， I have laid down very solid special field of one basis. And at the same time ， my thought is agile， to geospace information result of scientific research and the correlation between putting to use in production， have very keen feeling and deep interest， are rich start nature thought， practical experience having many projects. My shortcoming is not to have a self creative core theory or technology ， I think that this is also a chance as for me and then. 7 month of next year will get my Master's degree ， my major task is to be ready for graduation practice in this paragraph of time. I intend to spend the time doctor learning the environment academy enthusiastically accomplishing me in Canada Waterloo for 4 years place after graduating ， I already receive the entrance invitation coming to Waterloo university graduate school at present. I apply for this Ph.D candidate project cause as follows: (1) Master stage in me， I have participated in "5.12 earthquake remote sense information of laboratory collecting the group who appraises a project with the condition of a disaster" ， success in the disaster alleviation being responsible for collecting Canada and USA making use of radar portrait in taking precautions against natural calamities mainly has applied. That I discover the LiDAR technology in my this paragraph of time go into is that the three kinds technology and space all over the body measure new technique incorporate laser ， global positioning system (GPS) and inertial navigation system (INS) ， the person takes precautions against natural calamities in the remote sense ， surveying and mapping ， environmental monitoring， the medium field of disaster alleviation has the vast development prospect and applies need. Canada exactly is to be celebrated all over the world for environmental management and lidar technology but ， these all are that the long range develops the inter-disciplines and technology needing badly develop in Chinese present. I will be "land-based mobile LIDAR data processing and the application for Emergency Response " ， believe that I mimic Cheng returning back to homeland 4 years later ， in the Waterloo go into， will certainly be able to come out strong ， repay a motherland. (2) Chinas survey and draw the remote sense field having already got brilliant achievements on study of science ， put to use in production but in the technology as well as on our industry project administration， the country who falls behind over with Europe and America， much maximal technology accomplishment is thesis rather than product or serves. Study one big characteristics that the cooperation of equal importance with practice educates to be also that Waterloo university and the person run a school (co-operative education) ， the student will work in relevance organization to do practice during the period of the course is in progress ， that the cooperation that it carries out at present educates a plan is that the whole world is maximal. The chance will fully utilize educating in cooperation in the Waterloo study about ， me ， the practice applying for the company who arrives at the Canada space information field， study their project managerial experience and how a technology is changed for applying. Be tied in wedlock Chinese national conditions after returning back to homeland，concentrate efforts on to applying to surveying and drawing the direct high-effect of remote sensing technique field to service society. Besides， I am informed that the Confucius of Waterloo university academy already has inaugurated on the last year. By the friend that I learn enthusiastically in Waterloo， I also know to be short of the Chinese teacher at present also very to Confucius of Waterloo university academy. I already get in touch with there Confucius academy department director， and their Chinese writing to me expressing an ability for the aspiration very， satisfied and welcoming me to arrive at their academy being that the student takes lessons in Chinese after school. My sincerity and fervency that can use me as far as possible goes to help them to know and appreciate beautiful Chinese language and culture although my ability is limited， distance of 1.1 goes to use action to carry out my promise let self act as a regard society in the future ， person having contribution to development of society.

Wells-Brookfield Cone/Plate Rapid Determination Of Absolute Viscosity Introduction The Wells-Brookfield Cone/Plate Viscometer gives researchers a sophisticated instrument for routinely determining absolute viscosity of fluids in small sample volumes. Its cone and plate geometry provides the precision necessary for development of complete rheological data. Principle of Operation The Wells-Brookfield Cone/Plate Viscometer is a precise torque meter which is driven at discrete rotational speeds. The torque measuring system， which consists of a calibrated beryllium-copper spring connecting the drive mechanism to a rotating cone， senses the resistance to rotation caused by the presence of sample fluid between the cone and a stationary flat plate. The resistance to the rotation of the cone produces a torque that is proportional to the shear stress in the fluid. The amount of torque is indicated either on a dial or digital display， depending on model. This reading is easily converted to absolute centipoise units (mPa.s) from pre-calculated range charts. Alternatively， viscosity can be calculated from the known geometric constants of the cone， the rate of rotation， and the stress related torque. See Range Tables The correct relative position of cone and plate is obtained by following a simple mechanical procedure without the need for external gauges or supplementary instrumentation. The stationary plate forms the bottom of a sample cup which can be removed， filled with .5 ml to 2.0 ml of sample fluid (depending on cone in use)， and remounted without disturbing the calibration. The sample cup is jacketed and has tube fittings for connection to a constant temperature circulating bath. The system is accurate to within ?.0% of the working range. Reproducibility is to within ?.2%. Working temperature range is from 0oC to 100oC. 展开

During the preparation of the nano-products， these nano-units， such as nanoparticles， nanoclusters， nanowires and nanorods， can also self-assemble into the novel structural aggregates by several routes， including electron irradiation deposition [19]， chemical vapor deposition [20]， laser vaporization-condensation [21]， charge transferring [22]， an organic reagent-assisted method [23]， solution-liquid-solid method [24] and catalytic vapor-liquid-solid growth [25]. With these routes， various nanoscale or microscale aggregates can demonstrate novel architectures， including tree-like， web-like， spherical， nanowire-like， network and fishbone-like aggregates. As a well-known method for producing the nanocapsules， however， arc-discharge has been rarely used to synthesize the aggregates self-assembled by the nanocapsules prepared simultaneously in arc-discharge. Nevertheless， it is possible that the arc-discharge can be developed into a new way to synthesize the aggregates. In the present work， we utilized arc-discharge technique with modified strategies， involving changing the hydrogen pressure， introducing gadolinium - aluminum alloy ingot as the anode and adjusting the elements percent of the anode according to their evaporation pressure， to synthesize a new type of nanocapsules， with intermetallic compound GdAl2 as core and amorphous Al2O3 as shell， which enlarge the family of the magnetic nanocapsules. At the same time， the regularly aligned three-dimensional macro-aggregates self-assembled by the nanocapsules without any template and catalyst were simultaneously synthesized in arc-discharge process. 展开

What's therole of the Supercapacitor? The supercapacitor resembles a regular capacitorwith the exception that it offers very high capacitance in a small package.Energy storage is by means of static charge rather than of an electro-chemicalprocess that is inherent to the battery. Applying a voltage differential on thepositive and negative plates charges the supercapacitor. This concept issimilar to an electrical charge that builds up when walking on a carpet. Thesupercapacitor concept has been around for a number of years. Newer designsallow higher capacities in a smaller size. Whereas a regular capacitor consists ofconductive foils and a dry separator， the supercapacitor crosses into batterytechnology by using special electrodes and some electrolyte. There are threetypes of electrode materials suitable for the supercapacitor. They are: highsurface area activated carbons， metal oxide and conducting polymers. The highsurface electrode material， also called Double Layer Capacitor (DLC)， is leastcostly to manufacture and is the most common. It stores the energy in thedouble layer formed near the carbon electrode surface. 展开

REAL-TIME KINEMATIC GPS Real-Time Kinematic (RTK) is Trimble Navigation's Site Surveyor System available as a standard option upgrade to Trimble's 4000 series SE and SSE receivers. The Medicine Bow National Forest uses 4000 SSE and SE receivers in it's Boundary Management program. The use of RTK enables a surveyor to determine a corner's position， establish a corner without having to make traditional corner moves or to mark and post line as quickly as the surveyor could walk， all without having to post-process the data. The surveyor using RTK can perform corner search within a meter or a couple of centimeters of the true location without the need to traverse down the line. For some survey applications traditional kinematic GPS field procedures are preferred， since many points can be observed in a short period of time with occupation times of a minute or less. However until now， kinematic surveying required post-processing before the results were available. This made field stakeout of corner positions， corner search， line marking and posting， and evaluation of coordinate accuracy in the field impossible to do using kinematic techniques (Curry et al 1993). Now， the use of RTK technology makes these impossible traditional kinematic tasks possible. What is RTK? RTK is currently carrier phase observations processed (corrected) in real-time resulting in position coordinates to a 1-2 centimeter accuracy level being available to the surveyor in the field. In other words， what the surveyor sees is what he gets. RTK， consists of two or more GPS receivers， three or more radio-modems， a "fixed-plate initializer" ， and a handheld survey data collector/computer (TDC1). In RTK， one receiver occupies a known reference station and broadcasts a correction message (Compact Measurement Record or CMR2) to one or more roving receivers. The roving receivers process the information to solve the WGS-84 vectors by solving the integers in real-time within the receiver to produce an accurate position relative to the reference station. Precision of RTK is +/-2 cm + 2 ppm， with 1 ppm equating to 1 mm per 1 km (Trimble Navigation， 1993). The TDC1 is used to graphically display the processed results of the surveyors current position on the ground at that moment. The TDC1 has the capability for the surveyor to navigate within a couple of centimeters to a known or unknown coordinate position using Local， State Plane or Geographic coordinates. In real-time positions may be logged in the field， inverses performed， attributes (features) recorded， azimuths and distances between points calculated， and corners located. RTK， as with traditional kinematic GPS procedures， currently requires continuous satellite lock to be maintained. This restriction allows for RTK to be most effective in a non-canopied， no obstructions environment. 展开

Using the Phillips curve to analyze the dynamic impact of oil price fluctuation on U.S. inflation， Hooker (2002) first proposed this view and found that the relationship can be negligible in the later half of the study period [5]. Jones et al. (2004) also support this view by summarizing the related literature [6]. However， as Balke et al. (2008) pointed out that these documents only can explain the phenomenon of gradually weakened negative relationship， and it can not explain why the relationship now is positive [3]. So the existing literature can not effectively explain the cause of the changing relationship. Generally in the oil market the sources leading to price fluctuation are comprised of oil supply shocks， economic demand shocks and precautionary demand shocks. Oil supply shocks are the factors that impact oil price fluctuation through oil production volatility. Economic demand shocks are the world economic factors that impact oil price fluctuation through world oil demand volatility. Precautionary demand shocks are specific to the crude oil market and designed to capture shifts in the price of oil driven by higher precautionary demand associated with fears about the availability of future oil supplies. If oil price is driven by different factors， the economic consequences will be different. When commenting on the view of Blanchard and Gali (2007) [7]， U.S. energy economic research scholar Rotemberg (2007) [8] also pointed out that the dynamic changing relationship between oil price fluctuation and economic development can be interpreted from this angle， but he did not carry out theoretical and empirical analysis. This is precisely the source of the ideas of the paper. 展开

Anions are commonly found in the environment and biological systems. For instance， fluoride is widely used in dental care applications and exhibits inhibition of certain enzyme functions.1 In addition to playing a central role in biological regulation， chloride is also a major groundwater contaminant that can corrode steel and concrete.2 Thyroid hormone synthesis largely determines iodine content.3 Acetate is a possible tracer for malignancies and has been extensively investigated in prostate cancer and its metastases.4 Phosphate ion is biologically and environmentally significant.5 Cyanide exerts adverse effects on human health as well as environment at low concentrations. Determining anions concentration is thus of primary concern in many areas， including food processing， industry， and clinic analysis.6 However， hydrophilic anions， such as F- and Cl-， form strong hydrogen bonds with protic solvents. Therefore， developing fluorescent probes based on electrostatic interactions for anions functioning in polar protic solvents is both challenging and currently infeasible. 展开

Since the formation of a titanacyclopropane en route to cyclopropylamines can only occur with alkylmagnesium halides that contain a b-hydrogen atom， Grignard reagents without b-hydrogens appeared to be the most promising reagents for the synthesis of primary tert-alkylamines from nitriles (Scheme 1). Thus propionitrile (1a)， phenylmagnesium bromide (2) and Ti(Oi-Pr)4 were chosen to optimize the reaction conditions. In the protocol for the synthesis of cyclopropylamines，10 Ti(Oi-Pr)4 is already present in the diethyl ether solution of a nitrile， before two equivalents of the Grignard reagent are added. As this did not appear to be optimal for the synthesis of primary tertalkylamines， the Grignard reagent was added before Ti(Oi-Pr)4. With 2 equivalents of PhMgBr， 0.1 equivalent of Ti(Oi-Pr)4， and 1 equivalent of propionitrile (1a)， the primary tert-alkylamine 8a was not formed at all. With an equimolar quantity of Ti(Oi-Pr)4， the amine 8a was produced in a low yield (11%) but with 1 equivalent of Ti(Oi- Pr)4 and 3 equivalents of the Grignard reagent 2， a 60% yield of 8a was obtained. Monitoring of the reaction by workup of aliquots of the reaction mixture showed that the first addition of 2 to form the N-magnesio derivative of the corresponding imine was rapid， whereas the subsequent second addition of the Grignard reagent 2 required heating under reflux for up to 24 hours. In tetrahydrofuran instead of diethyl ether， the amine 8a was formed in a very low yield， if at all. 展开

The incorporation of silicon from the quartz-made growth chamber， characteristic of NIRIM-type reactor is insignificant in our samples， if any. The peak at 1.681 eV from the Si–V defect is totally absent from our films (not shown here)， which supports the good quality of these films. The improvement of the crystalline quality of {111} films is explained by the weak ion bombardment of the sample during its growth outside the plasma ball. Raman measurements (not shown in this work) have also confirmed the high crystalline quality of our films， in particular in the low doping range. Very high boron concentrations (up to 5×1021 cm−3) have been reached at this growth position， outside the plasma ball. 展开

Abstract In this paper， the general situation of research on agile fixture design is summarized and the achievements and deficiencies in the field of case-based fixture design are pointed out. There are no correlative case bases and matching mechanisms during the period from establishing the fixture planning to designing the fixture in currently used case-based fixture design systems. Thus a great amount of experience of fixture design is wasted and cannot be re-used， which reduces design efficiency and violates the original intention of case-based reasoning methods. In order to realize agility of fixture design， including re-configurability， re-scalability and re-usability， in this paper， a re-configurable agile fixture element base and an element assembly relation base are established. Using these two bases， the fixture structure is function-based decomposed， which makes it easy for an agile fixture to be re-configured and modified. Furthermore， a whole case-based agile fixture design model is presented， in which three modules are introduced， including the evaluation of the similarity of fixture planning， conflict arbitration and the modification of an agile fixture case. The three modules can be used to solve a problem where experience and design results cannot be re-used in the process of fixture design. Against the agile fixture design model， the evaluation method is put forward to evaluate the similarity in various phases. However， a similar case in the base could not generally meet the actual requirement and resolve the conflict between the similar case and the actual condition. Thus three methods， including a local restriction-relaxed method， a function-based conflict arbitration method and a case-based conflict arbitration method， are presented to clear up the conflict and could be used to modify the case to obtain an approach to a design result. Finally， an agile fixture design example is presented. The result demonstrates that the case-based agile fixture design approach can improve re-usability and design efficiency.

Wide-angle and low-angle X-ray powder diffraction (XRD) of the as-obtained samples were recorded on a Rigaku D/max-2500 with Cu Kα radiation (λ = 1.540 56 Å) operated at 40 kV and 200 mA. Raman measurements were performed using a DXR from Thermo Scientific with a laser wavelength of 532 nm. To calculate the pore size distribution and pore volumes， the nitrogen absorption and desorption isotherms were measured at 77.3 K with an Autosorb-1 specific surface area analyzer from Quantachrome. The content of N in N-doped porous carbon was determined by NHC elemental analysis using Flash EA 1112. Thermogravimetric (TG) analysis of S/C composite was performed on TG/DTA 6300 in an N2 flow to obtain the S content in the composite. A four-contact method was applied to measure the powder electronic conductivity of porous carbons. The powder sample was pressed to disk at 4 MPa with two stainless-steel plungers， whose resistance was measured by a Keithley 2400 digital multimeter in fourwire mode. The conductivity of the sample was calculated according to the resistance and the size of the disk. Information of the surface elements was obtained by X-ray photoelectron spectroscopy (XPS) performed on the Thermo Scientific ESCALab 250Xi using 200 W monochromatic Al Kα radiation. The 500 μm X-ray spot was used for XPS analysis. The base pressure in the analysis chamber was about 3 × 10−10 mbar. All reported data of XPS binding energy are calibrated based on the hydrocarbon C 1s line at 284.8 eV from adventitious carbon. Spectra were fitted with Lorentzian−Gaussian functions and smart background using Thermo Avantage software. 展开
