There is a growing interest in determining mercury(Hg) levels in the marine environment as well as in fish for human consumption. Methyl mercury(Me Hg)in particular is the most toxic and bioaccumulative form of mercury in food webs and it is the predominant chemical form making up 80%-90% of the total mercury present in fish muscle tissue.Hence，fish and other organisms at the end of the food chain constitute the major source of MeHg in the human . As outcome of this risk，MeHg has been classically monitored in fish， and methodologies for mercury speciaion have increased significantly since the early 1990s. Currently， microwave-assisted extraction (MAE) has provided an efficient alternative strategy to conventional techniques for solvent extraction of a large amount of organometals compounds.The analytical techniques most frequently applied for Hg speciation analysis involve GC(GasChromatography) ， GC-CICP-MS(Gas Chromatography -CInductively Coupled Plasma Mass Spectrometry) supercritical fluids chromatography (SFC)，ion chromatograph(IC)， HPLC-CCVAAS(High Performance Liqui Chromatography-Cold Vapor Atomic Absorption Spectrometry) or ICP-MS systems .Several authors recommended a back-extraction of mercury species from organic solvents to cysteine or sodium thiosulphate aqueous solutions .Because MeHg is the most common organomercury compound in biological materials ，here we offer a new simple and cost-effective method to determine MeHg. Basically， this method combines the microwave assisted extraction followed by clean-up with cysteine acetate solution and MeHg quantification by a direct mercury analyzer (DMA). 展開

After concentration in a rotary evaporator， the obtained material was dried in air at 383 K overnight and subjected to preliminary reduction with a 1N2/3H2 stream at 698 K， and then cooled in 1N2/3H2 atmosphere. The potassium promoter was introduced by incipient wet impregnation with KNO3 solution at room temperature with molar ratio of K+ /Ru = 5/1. After stirring for 6 h and infusing for 24 h， the samples were dried in a rotary evaporator at 343K and then dried in the air at 383K for 12 h. The ammonia synthesis activities of the catalysts with about 35-60 meshes were evaluated by 1N2/3H2 flow of 2100 mL/h at 0.2 MPa from 623 K to 773 K. The amount of effluent ammonia was determined by titration method. As we can see from the Table 1， under the same reaction conditions， the catalyst K-Ru/Mg(Al)O exhibited the highest activity， 38.42 mL NH3?h-1?g-1 at 673K， 3 times more active than K-Ru/MgO， 12.88 mL NH3?h-1?g-1 at 748K. This means that selection of supports takes great effects on the activity of catalysts. The ammonia synthesis activity of different supports are K-Ru/Mg(Al)O > K-Ru/Mg-Al-Ca(1) > K-Ru/Mg-Al-Ca(2) > K-Ru/Al2O3 > K-Ru/CaO > K-Ru/MgO. The combinatorial supports showed higher activity than single supports. However， the sequence of temperature corresponding to the highest activity is just opposite to that of the activity. The optimal temperature for K-Ru/Mg(Al)O， 673K， is the lowest of all， on the contrary， that of K-Ru/MgO is the highest， 748K. The Mg(Al)O has a larger surface area of 140.95 m2?g-1 ， similar to γ-Al2O3， 110-180 m2?g-1 . The other two combinational supports have little surface areas but higher activities than Al2O3. It suggested that the activity of the catalyst is influenced not only by the dispersion of Ru crystals but also by the crystal structure of the supports. Table 1 Ammonia synthesis activities and BET surface areas Catalyst Optimal activity Highest activity Surface area of support temperature(K) (NH3/mL?h-1?g-1) (m2?g-1) K-Ru/MgO 748 12.88 K-Ru/Al2O3 698 23.79 K-Ru/CaO 723 23.22 K-Ru/Mg(Al)O 673 38.42 140.95 K-Ru/Mg-Al-Ca(1) 698 30.75 29.10 K-Ru/Mg-Al-Ca(2) 698 26.12 14.69 Acknowledgments This work was supported by the NNSF of China (20273053， 20023001 and 29933040)， the 973 Programming (001CB108906) and the NSF of Fujian province (E0310001).

The elemental content of raw materials， phosphogypsum， substrate (potassium salt)， products (superphosphate and “Amofoska”)， soil， and grass was determined using conventional and epithermal neutron activation analysis using the IBR-2 pulsed fast reactor at Frank Laboratory of Neutron Physics (FLNP)， Joint Institute for Nuclear Research (JINR)， Dubna， Russia. The analytical procedure was described elsewhere by Frontasyeva and Pavlov [15]. Quality control was based on the application of certified reference materials (CRMs): IAEA-336 (lichens)， IAEA-SDM (lake sediment) and IAEA-SL1 (soil). The certified values and the results obtained by NAA were compared (Table 2). Concentrations of most elements were in good agreement with the CRMs except for Ti， Ni， Ce， Eu， Dy and Rb， which differed from the certified value as follows: Ti - 41.7 %， Ni - 26.5 %， Ce - 24.3 %， Eu - 32.9 % and Dy - 33.3 % in IAEA-SL1 (soil) and Rb - 20.6 % in IAEA-336 (lichens). For the 21 elements in agreement with the certified values the bias observed was below 20 %. For 11 elements (Al， V， Mn， As， Br， Sc， Cr， Sm， Na， Co and Sb)， the bias ranged from 0.03 % to 5 %， for 5 elements (Fe， Zn， Ba， Th and Cs) the bias was greater than 5 % but lower than 10 %， and for 5 elements (La， Tb， Hf， Ta and U) the bias was determined to be between 10 % and 20 %. Samples of raw materials， phosphogypsum， substrate， products， soil (of about 0.1 g)， and grass (0.3 g) were irradiated in cadmium-screened channels 1 and 2 of the pneumatic “Regata” system described elsewhere by Frontasyeva and Pavlov [15]. In order to determine elements associated with long-lived radionuclides， samples were irradiated for 100 hours. Spectra of induced gamma activity were recorded after 4 and 20-24 days of cooling. Short irradiations， 5 minutes for grass samples and 60 seconds for the remaining samples， allowed determination of Al， Ca， Cl， I， K， Na， Mg， Mn， Ti and V. Gamma-ray spectra were recorded after 5 and 12 minutes after irradiation. Data processing was performed using software developed at FLNP JINR [16， 17]. All gamma-spectrometers and counting electronics were made at JINR [16]. The software developed at FLNP JINR for peak searching， peak fitting， and nuclide identification routines were used for processing the amplitude spectra [16]. In the case of the lack of analytical data， there was a half of the detection limit inserted for each analyte [18]. Principal component analysis (classical PCA and fuzzy PCA) was performed as a tool for searching the possible correlations between environmental and industrial samples that could implicate the impact of phosphatic fertilizer production on the environment adjacent to the plant. 請給一個比較能看懂的翻譯，謝謝. 展開

In this paper， the degradation of an azo dye Orange G (OG) on nitrogen-doped TiO2 photocatalysts has been investigated under visible light and sunlight irradiation. Under visible light irradiation， the doped TiO2 nanocatalysts demonstrated higher activity than the commercial Dugussa P25 TiO2， allowing more ef?cient utilization of solar light， while under sunlight， P25 showed higher photocatalytic activity. According to the X-ray diffraction (XRD)， X-ray photoelectron spectroscopy (XPS) and UV–vis spectra analyses， it was found that both the nanosized anatase structure and the appearance of new absorption band in the visible region caused by nitrogen doping were responsible for the signi?cant enhancement of OG degradation under visible light. In addition， the photosensitized oxidation mechanism originated from OG itself was also considered contributing to the higher visible-light-induced degradation ef?ciency. The effect of the initial pH of the solution and the dosage of hydrogen peroxide under different light sources was also investigated. Under visible light and sunlight， the optimal solution pH was both 2.0， while the optimal dosage of H2O2 was 5.0 and 15.0 mmol/l， respectively. Azodyes， which are characterized by the presence of one or more azo bonds ( N N )， are among the most notorious widespread environmental pollutants associated with textile，cosmetic， food colorants， printing， and pharmaceutical indus-tries. Because of their non-degradability， toxicity， potential mutagenicity and carcinogenicity， wastewaters originating from these dyes production or application industries pose a major threat to the surrounding ecosystems and human beings’ health.[1–3].Environmental concerns and the need of meeting the strin-gent international standards for rejecting wastewaters has made the development of novel and cost-effective processes for the puri?cation of azo dyes ef?uents an issue of major technological importance. 展開

Caution:Do not place your finger over the vent(it pressurizes the sensor) to test the flow indicator when gas is flowing to the sensor.removing your finger (the restriction) generates a vacuum on the sensor and maydamage the sensor(voiding the sensor warraty). Positive pressure applications: If the sample pressure is greater than 30 psign an external pressure regulator(optional) is required upsteram of the analyzer to control of sample flow.a pressure regulator with a metallic diaphragm is recommended to prevent high oxygen reading that cuold result from the use of diaphragms constructed of more gas permeable materisls. If other optionoal sample system components such as coiled metal tubing(samples must be colled to at least 35-40℃ for continuous use)，coalescing filters ，scrubbers，etc.are required install the pressure rugulator after the coiled tubing and bofore the other components and the analyzer.a scrubber requires a flow valve upstream for optimum efficiency and response time and that the analyzer flow valve is opened completely. Atmospheric or slightly negative pressure applications: For accurate high ppb and/or low ppm range measurements，an optional simple pump is required downstream of the analyzer to draw the sample through the analyzer.The cacuum drawn on the analyzer and sensor should not exceed 4”of water. Caution:Use ofpump downstream of the sensor requires the floe control valve upstream of the sensor be completely opened to avoid drawing ercessive vacuum in the sensor，which can damage the sensor. If pump over-loading(due to the limitation of low flow rate of the sample gas)is a comsideration，a second throttle valve on the pump’s inlet side may be necessary to provide a bypass path，as illustrated below，to prevent the pump from over-loading and over-heating while miantaining the required sample flow rate within the above-mentioned parameters 展開

LABVIEW 虛擬儀器高手幫我翻譯下好嗎?: 4.VIRTUALINSTRUMENTAfoundationofthecontrolsystemdesignistheconceptofvirtualinstruments.Intraditionalobservatorysystemdesign，instrumentsaretypicallyconsideredentitieswhose... 4. VIRTUAL INSTRUMENT A foundation of the control system design is the concept of virtual instruments. In traditional observatory system design， instruments are typically considered entities whose design and components are fixed well in advance of actual use of the instrument. The approach works quite well when the role of the instrument is well understood with respect to the experiments it is to be used for. It also fits well with a system design where the instruments must be mounted on the telescope (e.g. mounting at the Cassegrain focus)， or exposed to the external environment - since the instrument is static， it can be more easily enclosed. However， this approach has some drawbacks in a laboratory style environment such as that provided by the ATST multiple-bench coude lab. In particular， providing the flexibility to explore new experiments results in a significant effort to adapt existing instruments to meet the requirements of the new experiment. The Virtual Instrument Model has been developed to address this issue， by abstracting the concept of an instrument from the specifics of the components used within that instrument. This allows the configuration of an instrument to be quickly adapted to meet the changes required by different experiments or changes to the laboratory environment. It should be noted that the virtual instrument is not a revolutionary concept but rather is the formalization of ideas often used in laboratory style experimentation. In the virtual instrument model， it is the experiment that drives the virtual instrument's 'design'. 4.1. EXPERIMENTS AND INSTRUMENTS Experiments are the heart of ATST operations and the control system is designed with this in mind. A laboratory style environment provides flexible support to carry out Experiments that are likely not understood or defined at the time the laboratory itself is designed. An Experiment undertaken at the ATST requires a Virtual Instrument. 不要機器翻譯的要人工的謝謝大家展開

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. 請不要用google的那個，我看不懂~~ 展開

LabVIEWTM (Laboratory Virtual Instrument Engineering Workbench) is a powerful instrumentation and analysis programming language for PCs running Microsoft Windows， Sun SPARCstations， Apple Macintosh computers， Concurrent PowerMax， and HP-UX workstations. LabVIEW departs from the sequential nature of traditional programming languages and features a graphical programming environment and all the tools needed for data acquisition， analysis， and presentation. With this graphical programming language， called “G，” you can program in a block diagram notation， the natural design notation of scientists and engineers. After you create a block diagram program， LabVIEW compiles it into machine code. LabVIEW integrates data acquisition， analysis， and presentation in one system. For acquiring data and controlling instruments， LabVIEW supports RS-232/422， IEEE 488 (GPIB)， and VXI， including Virtual Instrument Software Architecture (VISA) functions， as well as plug-in data acquisition (DAQ) boards.
