UNIPHOS-400 multiparameter UV/IR based Fire Detector detects fire by detecting simultaneously three important characteristics of fire viz. UV radiation in the solar blind region of 185-260 nm， IR emission from the hot CO2 which invariably is present in and around a fire and the continuum black body IR radiation from the fire. This microprocessor based detector is housed in a flameproof enclosure with a viewing window. It is mounted on a wall mountable stand with provision to adjust the field of view to bring the viewing window in line of sight of the likely spot where fire can occur. The detector gives a fire alarm (red led glows) when all the three chosen fire parameters are detected. Simultaneously a relay output is available. When any one of IR or UV radiation is detected yellow led glows to give a warn alarm and also a relay output is available. The detector also provides an analog 4-20mA output and a RS485 digital output to indicate the above events. 展开

药学英语翻译: Havingbrieflyexaminedthestructureoforganicpackingsandthevariousroutesintheirmanufacture，themostimportantfeaturesmaybesummarizedasfollows:>Hydrophilicaswellaslipophilicorg... Having briefly examined the structure of organic packings and the various routes in their manufacture， the most important features may be summarized as follows: > Hydrophilic as well as lipophilic organic packings are synthesized with a controlled pore and surface structure depending on the type of monomer/comonomer and the polymerization reaction. Surface structure can be altered by controlled consecutive surface reactions. > In accordance with the bulk composition， polymer packings are stable across almost the entire pH range， particularly under strong alkaline conditions. > Chemical stability is affected by oxidizing and reducing solutions. > Although cross-linking reactions have been optimised in as much as rigid pressure stable particles can be manufactured， some remaining swelling property is often noted when changing the solvent composition in HPLC. > As in the manufacture of silica， porosity， pore size， and surface area of polymer packings can be adjusted over a wide range， and micro-， meso-， and macro- as well as non-porous beads are synthesized reproducibly. 3.2.4.2 Hydrophobic Polymer Stationary Phases The synthesis of cross-linked copolymers of styrene and divinylbenzene has been studied intensively and is well documented. The starting monomer is styrene， and divinylbenzene (DVB) is used as cross-linker. The amount of DVB can reach up to 55wt.%. At 55% DVB， the copolymer shows practically no swelling and possesses a permanent porosity. Figure 3.21 illustrates the network structure of poly(styrenedivinylbenzene) (St-DVB). Commercial products differ in bead size and pore size. There are even non-porous products on the market， designed for the rapid separation of peptides and proteins by reversed phase HPLC (Maa and Horvath， 1988). St-DVB copolymers are stable in the pH range 0–14. They find increasing application in the separation of low molecular weight compounds， peptides， and proteins by means of reversed phase chromatography (Tanaka et al.， 1987， Tweeten and Tweeten， 1986) and as parent materials for the synthesis of derivatized packings in interaction chromatography of biopoly-mers (Unger et al.， 1987， Regnier， 1987). Numerous other organophilic polymer packings have been synthesized for size exclusion and interactive HPLC after suitable derivatization. They are reviewed in depth by Mikes (1988). 展开

Keywords: Epoxides; Amines; 2-Amino alcohols; Yttrium nitrate hexahydrate; Regioselectivity Amino alcohols constitute an important class of compoundshaving both chemical and biological applications. They are important pharmacophores present in various inhibitors and are used as building blocks for the synthesis of biologically active natural products， insecticidal agents and chiral auxillaries for asymmetric reactions.1a–f They act as starting materials for the synthesis of oxazolines which are useful in the polymer industry.1g Owing to their widespread applications， the synthesis of amino alcohols has received much attention in recent years. Traditionally， 2-amino alcohols are prepared by heating an epoxide with an excess of amine at elevated temperature. The use of a high temperature leads to undesired side reactions and also limits the applicability towards temperature sensitive substrates. To overcome these drawbacks various promoters such as ZnCl2，2 ScOTf，3 MgBr2OEt2，4 67 9 bismuth salts，5 CoCl2， CuBF4， DIPAT，8 Ti(OiPr)4， 1011 12TaCl5， ZrCl4， Sm(OTf)3， potassium dodecatungstocobaltate， 13 and aluminosilicate14 have been employed for the above transformation. The use of non-conventional techniques such as microwave irradiation at elevated temperaturehas also been reported.15 Recently， the use of Al(OTf)3 (1 mol %) as catalyst in toluene at reflux has also been reported.16 Although significant advances have been made in this area， low regioselectivity， longer reaction time， use of elevated temperature， high catalyst loading， toxic solvents and lower substrate compatibilitylimit their applications.Thus there is a need to develop an efficient catalytic protocol for ring opening of various epoxides with aliphatic， aromatic andheteroaromatic amines under ambient conditions 展开

The samples were prepared according to the Ohara process. XRD analysis revealed that the investment consisted essentially of SiO2， Mg2P2O7， SiO2•H2O and Mg2SiO4. SEM experiments combined with EDX analysis revealed the following atomic concentrations Si (62.6%)， Mg (19.7%)， P (17.1%)， and Ca (0.6%). After casting， the titanium samples exhibit a rough and irregular surface， and XRD analysis indicated that titanium contains essentially the α phase and traces of the β phase. After demoulding titanium samples， the investment side which was in contact with titanium was black colored， proving the reaction between titanium and the investment. XPS analysis performed on this side of the investment indicated that the Si 2p peak presents a shoulder on the low binding energy side and thus suggest that SiO2 has been transformed into metallic Si. 展开

Experiment SiO2 films with a thickness of 300 nm were grown on (100) p-Si substrates， with a resistivity of 4 W cm， using thermal oxidation at 1，000 C， for 90 min. Monte Carlo simulationcode (TRIM) was used to calculate the adequate energy in order to place the maximum Ge concentration at the middle of the SiO2 film. SiO2 matrices were implanted with Ge74+ ions at RT， with 250 keV energy， using implantation doses of [0.5， 0.8， 1， 2， 3 and 4] · 1016 cm–2. After ion implantation， the samples were annealed at 1，000 C for 1 h in a forming gas atmosphere to precipitate Ge and to form the nanocrystallites. Raman spectra were obtained using a triple grating T- 64000 Jobin-Yvon spectrometer， with 1 cm–1 spectral resolution. The 514 nm line of the argon laser was used to excite the samples. All samples were measured at RT; the laser power on the sample was 9 mW. The diameter of the laser spot was 50 lm and the integration time was 30 min. The resonant Raman spectra were obtained in the backscattering configuration. The orientation of the Si substrate is fundamental to polarize the laser light， allowing the second-order Raman Si peak， at about 300 cm–1， to be suppressed not masking the Raman peaks corresponding to Ge-nc. PL spectra were measured at RT with a 240 nm excitation source， using a Spex Fluoromax spectrometer with a R298 Hamamatsu photomultiplier. Compositional analysis of the SiO2 matrix was carried out using a DIGILAB infra-red Fourier transform spectrometer. The system was purged with dry N2 to reduce the infrared (IR) absorption from H2O and CO2. Transmittance measurements were carried out within the 400– 4，000 cm–1 range at 300 K. The beam spot size was about 5 mm diameter and the resolution was 4 cm–1. In all cases a non-processed Si substrate sample was used as a reference. Results and discussions Figure 1 presents the Raman spectra of the films implanted with various doses [0.5; 0.8; 1; 2; 3; 4] · 1016 cm–2， followed by annealing forming-gas， (92% N2 + 8% H2) at 1，000 C， for 1 h. The position of the peak for bulk Ge was determined at 302.4 cm–1 and this value is used to compare with Ge-nc peaks. The Raman spectra of the implanted samples clearly show three bands: 210–280， 304 and 430 cm–1. The first one， 210–280 cm–1， is associated with amorphous Ge compounds. Such band was expected as the samples have been annealed at 1，000 C， therefore above the Ge melting temperature (938.3 C) [10]. At this temperature， Ge precipitates as liquid droplets inside a viscous oxide matrix. The second band was near 304 cm–1， and can be associated with Ge-nc. This band is in good agreement with the work reported by Wu et al. [11]. Finally， the third band at 430 cm–1 is related to local Si–Si vibrations [12]. 展开

The scheduler function involves planning how to produce the current volume of orders in the FMS， considering the current status of machine tools， work-in-process， tooling， fixtures， and so on. [91 The scheduling can be done automatically or can be assisted by an operator. Most FMS control systems combine automatic and manual scheduling; the system generates an initial schedule that can be changed manually by the operator. The dispatcher function involves carrying out the schedule and coordinating the activities on the shop floor， that is， deciding when and where to transport a pallet， when to start a process on a machining center， and so on. The monitor function is concerned with monitoring work progress， machine status， alarm messages， and so on， and providing input to the scheduler and dispatcher as well as generating various production reports and alarm messages. A transport control module manages the transportation of parts and palettes within the system. Having an AGV system with multiple vehicles， the routing control logic can become rather sophisticated and become a critical part of the FMS control software. A load/unload module with a terminal at the loading area shows the operators which parts to introduce to the system and enables him or her to update the status of the control system when parts are3. Materials Handling System The automated materials handling system is a fundamental component that helps mold a group of independent CNC machines into a comprehensive FMS. The system must be capable of accepting workpieces mounted on pallets and moving them from workstation to workstation as needed. It must also be able to place workpieces on hold as they wait to be processed at a given workstation. The materials handling system must be able to unload a workpiece at one station and load another for transport to the next station. It must accommodate computer control and be completely compatible with other components in the flexible manufacturing system. Finally， the materials handling system for an FMS must be able to withstand the rigors of a shop environment. Some FMSes are configured with automated guided vehicles (AGVs) as a principal means of materials handling. 展开

The metal stripe of the thermostat have greatly different thermal expansion coefficients. When they are bonded together and heated， the metal with the high expansion rate elongates much more than the other strip. This causes the strips to bend and touch the contact point. The lead screw goes through a pair of half nuts， which are fixed to the rear of the apron. When actuating a certain lever， the half nuts are clamped together and engage with the rotating lead screw as a single nut， which is fed， together with the carriage， along the bed. The width of cut is the width of the workpiece in contact with the cutter in a direction normal to the feed. We can easily see that the width of cut should decrease with increasing depth of cut to keep the load and power requirement below those that can be met by the cutter and the machine tool， respectively. The control unit coordinates the operations of all the other components. It controls the input and output information between the computer and the outside world through the I/O section， synchronizes the transfer of signals between the various sections of the computer， and commands the other sections in the performance of their functions. 展开

This paper presents a procedure for preparing a nanofluid which is solid–liquid composite material consisting of solid nanoparticles with sizes typically of 1–100 nm suspended in liquid. By means of the procedure， Cu–H2O nanofluids with and without dispersant were prepared， whose sediment photographs and particle size distribution were given to illustrate the stability and evenness of suspension with dispersant. Aiming at the dispersion of nano-Cu is regarded as the guide of heat transfer enhancement， the dispersion behavior of Cu nanoparticles in water were studied under different pH values， different dispersant types and concentration by the method of zeta potential， absorbency and sedimentation photographs. The results show that zeta potential has good corresponding relation with absorbency， and the higher absolute value of zeta potential and the absorbency are， the better dispersion and stability in system is. The absolute value of zeta potential and the absorbency are higher at pH 9.5. Hexadecyl trimethyl ammonium bromide (CATB) and sodium dodecylbenzenesulfonate (SDBS) can significantly increase the absolute value of zeta potential of particle surfaces by electrostatic repulsions， and polyoxyethylene (10) nonyl phenyl ether (TX-10) can form a thick hydration layer on the particle surfaces by steric interference， which leads to the enhancement of the stability for Cu suspensions. In the 0.1% copper nano-suspensions， the optimizing concentrations for TX-10， CATB， and SDBS are 0.43， 0.05， and 0.07%， respectively， which have the best dispersion results. . 2007 Elsevier Inc.

Herein， we present a template approach that allows for the incorporation of normally labile metal centers， such as copper(I)， copper(II)， and silver(I)， into DNA branch points(Scheme 1 a). Remarkably high structural stability and chir-ality transfer to the metal complex are demonstrated. More-over， we have used this approach to generate the first example of a dynamic multimetallic metal–DNA assembly， with three metal complexes as the corners， single-stranded DNA as the sides， and multiple DNA double strands at the periphery (Scheme 1 d). We demonstrate quantitative and reversible structural switching of these metal–DNA nanostructures by adding specific DNA strands， resulting in controlled modu-lation of the metal–metal distances.This contribution thus allows the programmable generation of structurally dynamic multimetallic metal–DNA assemblies， with anticipated appli-cations in nanoelectronics， nanooptics， artificial photosyn-thesis， high-density data storage， and catalysis. To create stable and electroactive metal–DNA junctions，we examined the attachment of the ligand bis(2，9-diphenyl)-1，10-phenanthroline (dpp) to DNA (Scheme 1 a). This ligand has been used by the groups of Sauvage and others to generate interwoven structures.[10]It forms complexes such as [Cu(dpp)2]+， whose redox potential falls within the compat-ible window for DNA bases (+ 0.8 to-0.7V vs. saturated calomel electrode， SCE) 展开
