Experimental Method All experiments were carried out in a high-pressure CO2 apparatus (Speed-SFE from Applied Separations) (see Figure 1) with a 300-mL extractor designed for a maximum pressure of 690 bar and a maximum temperature of 250 °C. The volume of the extractor had to be reduced to 50 mL by a metallic cylinder， which tightens to the extractor wall， because as preliminary tests showed the equilibrium cell has to be completely filled with material. Otherwise， diffusion is the limiting factor and time for reaching equilibrium was too long. The extraction vessel was filled with compressed CO2 by an air-driven pump at closed outlet valves and under static conditions， which means desired pressure and temperature; the cell was incubated for 15 h， maintaining these conditions to reach equilibrium. In preliminary experiments the equilibrium time of 15 h was determined to reach equilibrium. CO2 Sampling. At equilibrium a CO2 phase sample is taken by opening the outlet valve and expanding a certain amount of CO2-substance mixture into a cooling trap filled with toluene， which has the highest solubility for the measured substances under atmospheric conditions. The pure gaseous CO2 passes a rotameter， showing the actual flow rate， and a gas flowmeter for determining the expanded CO2 amount. The content of the cooling trap was filled up with toluene to 30 mL and analyzed by a gas chromatographic method using an electron capture detector (GC-ECD). With the mass of expanded CO2 and composition of the cooling trap solubility at a certain pressure and temperature was calculated. Sampling was repeated four times at a given pressure and temperature and the standard deviation was lower than 5%. Gas Chromatographic Method. The tolueneflame retardant mixture of CO2 sampling was analyzed in a gas chromatograph (HP 5890 Serie II) with an ECD using a capillary column (type HP-1， 12 m 0.2 mm 0.2 ím). The injector temperature was held constant at 290 °C and the detector temperature at 300 °C. The oven temperature was held constant at 290 °C. Calibration with different amounts of HBCD and TBBA in toluene has been done before determining the linear range of calibration line and retention time of substances 展開(kāi)

The most common means of agitation of liquid media is by placing the culture vessels on a drum(for test tubes)or a disk(for flasks)slowly rotating around a near horizontal axis. This assures good aeration of the liquid cultures with little mechanical damage to the cells.Agitation can also be achieved by placing culture flasks on reciprocating or gyrotory platform shakers.Gyrotoy (horizontal rotary orbit)shakers are preferred over reciprocating (horizontal linear motion)ones for a variety of reasons .The performance of the gyrotory shaker is determined by the speed of agitation and angle position of the flasks，with optimal aeration occurring in flasks tilted about 45° from the vertical.A new shaker design is the "tapping" motion shaker in which the culture is agitated by a magnetic bar moving up and down.This vertical movement of the bar is less injurious to cells than rotary movement of the bar at the bottom of the flask used in some conventional culture systems. 展開(kāi)

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. 展開(kāi)

- 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(jī)器翻譯的 要人工的 謝謝大家 展開(kāi)

Fig. 1 shows that diamond particles are dispersed in the copper matrix. Since the diamond particles are easy to be stripped off during mechanical polishing， small pits are left on the surface of samples. When the samples were analyzed by electron probe for carbon， the particles displayed high carbon peaks， as shown in Fig. 2. Fig. 3 exhibits the analyzed result for extracted product of the copper–diamond composite by X-ray diffraction (XRD) analysis. It is shown that three dif- fraction peaks exist， shown as A， B and C， respectively. The interplanar distances corresponding to the three peaks and standard ones for diamond are compared in Table 1. The measured values of the interplanar distances are in good agreement with the standard ones， demon- strating that the extracted product should be the carbon in diamond state. Fig. 4(a) gives a TEM micrograph showing distribution and morphology of diamond particles (indicated as A， B， and C) in the copper–diamond composite. The calibration of interplanar distance for diffraction rings in Fig. 4(b) was given in Table 2. Compared to Table 1， it is also demon- strated that the calibrated interplanar distances for the diffraction rings conform to the standard ones of diamond. Therefore， it is believed that the graphitization of diamond particles hardly occurs after sintering at 1150–1220 K in the copper–diamond composite. Although diamond is a metastable allotropic modifica- tion of carbon， the graphitization of diamond particles in the copper–diamond composite did not occur， or the degree of graphitization was too small to be found. It is believed that the beginning temperature of graphi- tization would be associated with the purity of diamond powders. The impurities such as some metallic elements reduce the beginning temperature of diamond graphitiza- tion. When diamond is fabricated by the static synthesis method， Fe and Ni are often used as catalysts and are present in diamond as impurities to decrease the beginning temperature of graphitization [6]. It is understandable that both for the graphitization and its reverse reactions， their activation energies can be decreased by catalytic agents. Compared with the diamond fabricated by static synthesis， the diamond powders prepared by explosion method do not contain metallic impurities， thus leading to an obvious increase in the beginning temperature of graphitization. Hence， the detonation synthetic diamond might be more resistant to graphitization and probably suitable for the electric contact materials. 展開(kāi)

- LabVIEWTM(LaboratoryVirtualInstrumentEngineeringWorkbench)isapowerfulinstrumentationandanalysisprogramminglanguageforPCsrunningMicrosoftWindows，SunSPARCstations，AppleMaci... 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. An instrument library with drivers for hundreds of instruments simplifies instrument control applications. For analyzing data， the extensive Analysis library contains functions for signal generation， signal processing， filters， windows， statistics， regression， linear algebra， and array arithmetic. Because LabVIEW is graphical in nature， it is inherently a data presentation package. LabVIEW can generate charts， graphs， and customized， user-defined graphics. 盡量翻的好一點(diǎn)，謝謝 能不能對(duì)GOOGLE自動(dòng)翻譯過(guò)的稍加修改下 展開(kāi)

Are the urban soils of Guangzhou polluted? In a review of heavy metal pollution of soils in china，chen et al.(1999) suggested that“Heavy-metal soil polltion is defined as the phenomena where the heavy-metal content in soils exceeds natural background levels and causes ecological destruction and deterioration of environmental quality” Table 6 compares the Guangzhou date with some background date and also some critical and trigger limits derived from the Netherlands and U.K. It can be seen from Table 6 that all top soil heavy metals，with the exception of Ni in the Park，are above the average value for Guangdong province. They also，again with the exception on Ni in the park，exceed the values for samples from Hainan Island，which affords a“clean”baseline data sea for the region. what is also of interest is that if the rations of heavy metal content for roadside sites in Guangzhou are compared to the Hainan data in from of a ratio then ratios of 3.09，1.04，4.16，1.84 and 1.59 are obtained for Cu，Ni，Zi，Pb and Cu respectively. With the exception of the 4.16 for Zn they are not dissimilar to rations of roadside to park top soil reported previously for Guangzhou. This suggests that the roadside to park comparison for soils in Guangzhou may pick up enhancement of heavy metals associated with vehicular traffic. 展開(kāi)
