These detectors may alter the view of a signals appearance, depending on which is selected. Each detector can show a different picture on the same signal because of the way the detector functions. An important selection to our spectrum analyzer is the amount of digital snap shots to be taken. This will be the amount of digital snapshots that is taken in the allocated bandwidth before showing a picture. With this said, the more sampling that is put into the spectrum analyzer the slower it will seem to update, but more opportunity to capture ingress and other interference that can happen inside a cable plant. Dwell Wide- Dwell Wide takes the largest snapshot out of the amount taken, then the 7.5 MHz spectrum is peak held as the 860 DSPI tunes across the selected frequencies in 250 kHz steps. Example: In Dwell Wide, with a 32 sampling rate set, this in turn means the 860 will dwell or sit on a portion of the spectrum defined above, take 32 snap shots, and then display the picture with the max amplitude before moving on to the next portion of bandwidth. Dwell Narrow- Dwell Narrow takes the largest snapshot out of the amount taken, then a 250 kHz spectrum slice is peak held as the 860 DSPI tunes across the selected frequencies in 250 kHz steps. The difference between Dwell Narrow and Dwell Wide is that Dwell Narrow only peak holds across a 250 kHz slice, where as Dwell wide peak holds the entire 7.5 MHz. Example: In Dwell Narrow, with a 32 sampling rate set, this in turn means the 860 will go to the first 7.5 MHz of the spectrum it will look at a 250 kHz slice of the 7.5 MHz and take its 32 samples. These 32 samples will be done in a peak hold fashion, then display the sample that contains the largest signal. Averaging: This detector when selected looks at a 7.5 MHz portion of the spectrum. When it tunes to the first 7.5 MHz portion of the spectrum, it takes into account how much sampling is selected, then takes it’s digital snapshots on the entire 7.5 MHz, averages those pictures together, then shows the final averaged picture. This detector is used for looking at large amounts of bandwidth. Example: In Averaging, with a 32 sampling rate set, this in turn means the 860 will go to the first 7.5 MHz of the spectrum, take it’s 32 digital snap shots, average those together, and show the average of the 32 snapshots. 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

Residues of malachite green (MG) were extracted from homogenized animal tissues with a mixture of McIlvaine buffer (pH 3.0)–acetonitrile, and purified over an aromatic sulfonic acid solid-phase extraction column followed by HPLC or LC–ESI-MS–MS analysis. Ascorbic acid and N,N,N9,N9-tetramethyl-1,4-phenylenediamine dihydrochloride were added to reduce de-methylation of the dye. Responses were recorded at 620 nm (HPLC) or by multiple-reaction-monitoring (LC–MS–MS) after post-column oxidation using PbO2 . MG and its primary metabolite leuco-malachite green (LMG) were successfully determined at 2.5–2000 mg / kg in catfish, eel, rainbow trout, salmon, tropical prawns and turbot, with a limit of detection at 1 mg / kg (HPLC) and 0.2 mg / kg (LC–MS–MS) for both MG and LMG. Recoveries for LMG were between 86±15% (prawn) and 105±14% (eel). Freeze–thawing cycles, and storage at 4°C and -20°C affected the recovery of both MG and LMG. Analyses of eel, trout and (processed) salmon field samples collected at local retailers, fish-market and -shops demonstrated trace levels of MG-residues. A McIlvaine solution at pH 3.0 was prepared by mixing 18.9 ml 0.2 M sodium hydrogen phosphate and 81.1 ml 0.1 M citric acid, whereas these volumes were 62.5 and 37.5 ml, respectively, to obtain a McIlvaine solution at pH 6.0. The SPE-eluent was prepared just before use and consisted of a mixture of 2.5 ml 25% (m/v) ammonium hydroxide, 2.5 ml 1.0 mg/ml methanolic ascorbic acid and 45 ml methanol. The sample-solvent was composed, just before use, from 2.5 ml 1.0 mg/ml methanolic ascorbic acid, 20 ml 50 mM sodium perchlorate containing 25 mM sodium acetate and 25 mM 1-pentanesulfonic acid adjusted to pH 4.0 with acetic acid, and 27.5 ml acetonitrile. Chemicals and solutions containing the dyes were protected from light. Fish were bought at the fish market and local stores. Blank trout were collected from aquaria at Utrecht University (The Netherlands). Tropical prawns were collected by the Dutch Inspectorate for Health Protection and Veterinary Public Health. 展开

The presence of a gaseous environment in the specimen chamber modifies the electron beam profile. In order to fully understand the beam-gas interaction, we have investigated the beam-diameter effect for two gases (helium and air) by Monte Carlo simulation. In this calculation, we have assumed that the electron beam is Gaussian and we have explored the influence of the nature of the gas at low voltage. When the beam diameter varies between 1 and 100 nm, there is no influence on the beam profile for these two gases. The resolving power of the HPSEM is not affected by the beamgas interaction. These theoretical results have been compared with experimental images obtained at low voltage under air and helium gases. The variation of image quality at low voltage has confirmed the interest of helium for use in a Field Emission Gun SEM (FEGSEM) in high pressure (or low vacuum) conditions. q 2004 Elsevier Ltd.

Plant material and culture conditions have been described (7). Briefly, a diploid tissue culture line, WOO1C, of wild carrot, Daucus carota L., was maintained in Murashige and Skoog medium supplemented with 0.1 mg of 2,4-dichlorophenoxyacetic acid (2,4-D). To regenerate plants from the culture, callus tissue was transferred to the same medium devoid of 2,4-D (embryogenic medium). All experiments were performed with cultures grown in liquid medium. For convenience, cultures grown in 2,4-D-containing medium are referred to as "callus cultures", and those grown in medium without 2,4-D as "embryo cultures." The growth of callus cultures was measured by the sidearmturbidity method (7). The number of cells at any time point of growth was estimated from turbidity in a Klett-Summerson calorimeter and was expressed in arbitrary units. For example, Klett 100 corresponds to ="2 X 106 cells per ml. The relationship is linear up to Klett 150 in our Klett-Summerson colorimeter. Suspension cultures ofWOOLC cell line are normally maintained at cell densities between 106 and 107 cells per ml in 0.1 mg of 2,4-D per liter (high-density culture) in shake flasks. During a quantitative study on embryogenesis, we found that maximal embryo production can be achieved by first incubating the culture at high density in medium without 2,4-D for one generation time and then diluting it to 2-3 x 104 cells per ml (low-density culture). To compare cultures of comparable density, callus cultures and embryo cultures were subjected to the same procedure. To initiate low-density embryo or callus cultures, an 8-day-old high-density culture grown at the logarithmic phase was washed three times with fresh callus or embryogenic medium and resuspended at 8 x 105 cells per ml for one generation (3 days) in its corresponding medium. It was then diluted to 2 x 104 cells per ml; 20 ml of the culture was incubated in a plastic Petri dish (9 cm in diameter) at 240C. The morphogenetic events of the cultures were examined and photographed under a dissecting microscope. 请不要用google的那个,我看不懂~~ 展开

A reversed-phase ion-pairing high-performance liquid chromatography (RP-HPIPC) method for the separation of a complex mixture of heparin-derived oligosacchrides has been developed by a stepwise optimization of the mobile phase, in which the concentration of ion-pairing reagent, mobile phase pH, and acetonitrile concentration were varied. The resolution of more than 30 oligosaccharide components was obtained, under optimized conditions, in an analysis time of less than 30 min. This represents the first RP-HPLC method that can separate a complex mixture of both small and large sulfated oligosaccharides in a single chromatographic step. The heparin-derived oligosaccharides, in this mixture, can also be separated under a second set of RP-HPIPC conditions using a volatile ion-pairing reagent, tributylammonium acetate, to aid in the recovery of individual sulfated oligosaccharides. Moreover, it was possible to replace sodium chloride gradient, required for eluting highly sulfated oligosaccharides, with a fixed, low concentration of a volatile salt, ammonium acetate, by utilizing an acetonitrile gradient. This solvent system might make it possible to directly interface this RP-HPIPC separation with mass spectral analysis. 2003 Elsevier B.V. All rights reserved.

After dryness, the powder was sintered at different temperatures for 24h in air. The X—ray diffraction was carried out with a Rigaku 12 kW rotary X—ray diffractometer with Cu Ka radiation and a graphite monochromator. Thepowder sample was examined with 2θ varying from10℃ to 75℃.The X—ray diffraction data for the samples sintered at different temperatures showed lines that could be indexed based on the spinel structure. The Raman spectra were excited from the samples held at room temperature,at an excitation wavelength of 517.4 nm and with a Nd—YAG laser operated at 1064 cm 1and 10 mW . The spectra were recorded on a Renishaw Raman spectrometer with the sample mounted in a backscattering(180°) geometry and at a resolution of 4 cm -1. Results and Discussion Although all the diffraction lines can be fitted with a spinel structure very well,we cannot unambiguously distinguish the layered α一NaFeO2 structure(space group R3m )from the spinel structure(space group Fd3m ) only based on those X—ray diffraction data. Raman spectroscopy must be employed to identify the real structure of the materials. Ammundsen et al. have calculated the Raman—active modes for spinel structure based on factor group analysis,showing that there should be five bands for the spinel structure. Fig.2 shows the Raman spectra of LiMn204 sintered at 500 and 600 ℃. There is a significant difference between the spectra from the samples sintered at these two temperatures,i.e.,there are five Raman peaks for the sample sintered at 500 ℃ and only two peaks for the sample sintered at 600 ℃ .Five calculationpredicted Raman—active modes for LiMn204 are one mode of Alg symmetry,one mode of Eg symmetry,and three modes of T2g symmetry .Accordingly, LiMn204 sample sintered at 600 ℃ seem s not to be crystallized in the spinel structure,while LiMn204 sample sintered below 500 ℃ is crystallized in the spinel structure.Usually,the low—temperature(LT) phase of LiCoO2 exhibits the spinel stucture,while the high—temperature(HT ) phase of it exhibits the α一NaFeO2 structure. According to our Raman data,the LT phase of the LiMn204 powder exhibits the spinel structure, which displays the same tendency as LiCo02 materia1. 展开
