IFRS 13 will help increase transparency when entities use models to measure fair value， particularly when users need more information about measurement uncertainty， such as when the market for an asset or a liability has become less active. IFRS 13 requires entities to disclose information about the valuation techniques and inputs used to measure fair value， as well as information about the uncertainty inherent in fair value measurements (which was of particular concern during the global fi nancial crisis). Some of those disclosures， including the fair value hierarchy， were already introduced in March 2009 through an amendment to IFRS 7 Financial Instruments: Disclosures. Those disclosures have been relocated to IFRS 13. The requirements in IFRS 13 also incorporate the guidance in a FASB Staff Position (FSP) issued in April 2009. 展開

Wells-BrookfieldCone/PlateRapidDeterminationOfAbsoluteViscosityIntroductionTheWells-BrookfieldCone/PlateViscometergivesresearchersasophisticatedinstrumentforroutinelydete... 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. 展開

A new kind of TiO2 nanotube array/Ni(OH)2 (TiO2/Ni(OH)2) composite electrode with the storage ability of light energy was prepared by the deposition of Ni(OH)2 on the TiO2 nanotube array， which was synthesized by anodizing Ti foils in an HF aqueous solution. SEM and XRD results showed that Ni(OH)2 particles were well distributed on high density， well-ordered and uniform TiO2 nanotube arrays. The photoelectrochemical properties of the TiO2/Ni(OH)2 electrode were investigated in NaHCO3/NaOH buffer solution (pH 10) by means of UV–vis absorption spectra， cyclic voltammogram (CV) and photocurrent measurements. It was found that the TiO2/Ni(OH)2 electrode was highly sensitive to light and exhibited excellent photoelectrochromic properties. Upon UV irradiation， the photogenerated holes by TiO2 nanotube arrays can oxidize Ni(OH)2 to NiOOH， and thus the TiO2/Ni(OH)2 electrode can be photo-charged by light。1. Introduction Among many visible light photocatalysts， TiO2nanostructures have attracted much attention due to high photocatalytic activ-ity， nontoxicity， chemical stability and huge potential applications [1–6]. The TiO2 nanotube array is one of most attention-getting TiO2nanostructures because of large surface area and outstanding charge transport properties. TiO2nanotube arrays can be utilized in dye-sensitized solar cells[7–9]， photocatalysis and hydrogen gas sensing [10]. So far， a variety of methods have been attempted to prepare TiO2 nanotube arrays， such as hydrothermal synthe-sis[11]， Langmuir–Blodgett technique [12]， solution casting [13] and anodization technique[10，14]， etc. Among these methods， the anodization technique has many advantages of low cost， low tem-perature and easy to be scaled up to large-area preparation. Recently， anewkindof photo-functional systemwith theenergy storage ability has been developed by coupling TiO2 photosen-sitive electrode with energy storage materials. In Takahashi and Tatsuma’swork[15]，aTiO2/Ni(OH)2bilayer thinfilmwas suggested for the oxidative energy storage. In this case， a redox-activep-type semiconductor Ni(OH)2is coupled withn-type TiO2photocatalyst to formap–njunction，WhenTiO2is illuminatedby light， holesgen-erated at the junction are separated from excited electrons， trans-ported into the bulk of Ni(OH)2and oxidized Ni(OH)2to NiOOH. Therefore， the oxidative energy storage system was constructed 展開

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. 展開

LabVIEWisapowerfulandcomplexprogrammingenvironment.LabVIEWisshortforLaboratoryVirtualInstrumentEngineeringWorkbench.Itisapowerfulandflexibleinstrumentationandanalysissoft... LabVIEW is a powerful and complex programming environment. LabVIEW is short for Laboratory Virtual Instrument Engineering Workbench. It is a powerful and flexible instrumentation and analysis software development application created by the folks at National Instruments—a company that creates hardware and software products that leverage computer technology to help engineers and scientists take measurements， control processes， and analyze and storem data. National Instruments was founded over twenty-five years ago in Austin， Texas by James Truchard (known as Dr. T)， Jeffrey Kodosky， and William Nowlin. At the time， all three men were working on sonar applications for the U.S. Navy at the Applied Research Laboratories at The University of Texas at Austin. Searching for a way to connect test equipment to DEC PDP-11 computers， Dr. T decided to develop an interface bus. He recruited Jeff and Bill to join him in his endeavor， and together they successfully developed LabVIEW and the notion of a “virtual instrument.” In the process they managed to infuse their new company—National Instruments—with an entrepreneurial spirit that still pervades the company today. Engineers and scientists in research， development， production， test， and service industries as diverse as automotive， semiconductor， aerospace， electronics， chemical， telecommunications， and pharmaceutical have used and continue touse LabVIEW to support their work. LabVIEW is a major player in the area of testing and measurements， industrial automation， and data analysis. For example， scientists at NASA’s Jet Propulsion Laboratory used LabVIEW to analyze and display Mars Pathfinder Sojourner rover engineering data， including the position and temperature of the rover， how much power remained in the rover’s battery， and generally to monitor Sojourner’s overall health. LabVIEW provides an extensive library of virtual instruments and functions to help you in your programming. It includes conventional program debugging tools with which you can set breakpoints， single-step through the program， and animate the execution so you can observe the flow of data. 畢業(yè)設(shè)計(jì)急用，望高手幫忙翻譯一下 展開

Physical and physicochemical characterization The particle size distribution of the Ch-zeolite was determined using a laser diffraction equipment (CILASk 1064) and standard wet sieving (Mesh Tylerk series). Scanning electron microscopy (SEM-PHILIPSk XL20) was used for photomicrographs as well as to analyse the Ch-zeolite composition (Energy Dispersion X-ray， EDX). The sample was initially placed in a vacuum chamber for coating with a thin layer (few nanometers) of gold (Au). The specific surface area of the material was measured by the methylene blue technique and by nitrogen gas adsorption methods， with the latter also providing information about particle porosity. In the methylene blue adsorption method， aqueous solutions (50 ml) of methylene blue (100 mg l 1) were agitated using an orbital shaker (Marconik) for an hour at room temperature in the presence of different quantities of the Ch-zeolite (0.05–0.3 g). The suspensions were then allowed to settle for 23 h and the resulting supernatants were centrifuged at 5000 rpm before the analysis of the residual methylene blue concentration. Results obtained correspond to averaged values of three different experiments. The specific surface area was evaluated by the Langmuir model， assuming the formation， at high concentrations， of a dye monolayer and 1.08 nm2 molecule 1， for the cross-sectional area (Van den Hul and Lyklema， 1968). The Ch-zeolite specific surface area was evaluated by the nitrogen gas adsorption method， using automated equipment (Autosorb 1-Quantachrome Instrumentsk)， employing multipoint BET isotherm adsorption data fitting. Also from these data， the porosity of the material was evaluated through parameters such as volume of total pores (d < 206 nm)， surface area and volume of micropores (d < 2 nm; Micropore Analysis Method). Zeta potential measurements for the natural and ammonia loaded zeolite， as a function of medium pH， were determined using a Zeta Plusk equipment (Brookhaven Instruments). Suspensions (0.01% v/v) of the Ch-zeolite， previously sieved below 37 Am (400 Mesh Tylerk)， in a 10 3 mol l 1 solution of KNO3 were used and the medium pH was controlled with the addition of HNO3 (pH< 7) and KOH (pH>7)， separately. For the Ch-zeolite saturated with ammonia， suspensions of the material were prepared by the same procedure， except that the sample was loaded with 100 mg NH3–N l 1 of ammonia. 展開

Attaching the Sample Chuck You will need a #2 Phillips screwdriver for this step. Following the details shown in Fig. 2-4， install the sample chuck by first aligning the pins on the bottom of the sample chuck with the receptacles on the alpha- SE base. Then tighten the upper two captive thumb screws. Next， use the Phillips screwdriver to tighten the lower two captive screws. Don’t over tighten the screws! It will make it difficult to remove them in the future; just ensure that the screws are snug. Finally， connect the vacuum line from the sample chuck to the vacuum fitting on the alpha-SE base. Releasing the Z-stage Shipping Lock To access the Z-stage shipping lock， first loosen the captive screw on the lamp/shipping lock access door， then open the access door by rotating 180°， as shown in Fig. 2-5. To release the Z-stage shipping lock， stand in front of the ellipsometer and use your left hand to balance the weight of the Z-stage (you will feel it lift up slightly). It will be difficult to release the shipping lock if you apply too much or not enough upward force. Next， use your right hand to move the shipping lock to the operating position (to the right， see Fig. 2-6). If the lock is hard to move， you can use a tool to gain more leverage. The shipping lock will move about 1/3” [8mm] to the right. Checking the Lamp Check that the QTH lamp in fully seated in the lamp housing. The lamp is located behind the actuator screw (see Fig. 2-6) and has two white wires protruding from the back of the lamp. Simply push down on the lamp ensuring that the lamp is fully seated in the lamp housing. Rotate the lamp/shipping lock access door to the closed position and hand tighten the captive screw. 拒絕翻譯軟件，翻譯軟件我自己也會(huì)用 不是用翻譯軟件我就看不懂，只是，上來找人翻譯就是希望翻譯出比較容易看懂，不需要自己對(duì)照就可以看的說明書，如果用翻譯軟件，根本就詞不達(dá)意，還是要自己對(duì)著原文件核實(shí) 既然用了那么多積分，就希望有相當(dāng)?shù)某晒?，如果用翻譯軟件混積分，那就是人品問題了 還有，某些人不要不懂亂說混積分 展開

Theelementalcontentofrawmaterials，phosphogypsum，substrate(potassiumsalt)，products(superphosphateand“Amofoska”)，soil，andgrasswasdeterminedusingconventionalandepithermaln... 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(qǐng)給一個(gè)比較能看懂的翻譯，謝謝. 展開
