高純度鍺 的英文怎麼說
中文拼音 [gāochúndùzhě]
高純度鍺
英文
high-purity germanium-
It ' s a more accurate method in determining the isotopic abundance of uranium. the paper describes the measurement principles that allow accurate measurements to be taken on samples of arbitrary size, shape, and measurement geometry - and of arbitrary physical and chemical composition - through the use of know nuclear decay data ( half - lives and branching intensities ). this method relies on internal gamma - ray peaks from the spectrum under analysis to self - calibrate the unknown spectrum for energy and peak shape
本工作首次分析了pc fram軟體的演算法並使用高純鍺探測器探測歐共體低濃鈾標準樣品,使用pc fram軟體的預設參數並不能得到準確的富集度值,通過大量的實驗,本工作對鈾富集度測量中的關鍵問題進行了初步的研究並給出了本實驗室條件下準確分析鈾富集度的修正參數和條件。Nuclear instrumentation - high - purity germanium crystals for radiation detectors
核裝置.放射探測器用高純度鍺晶體Test procedure for high - purity germanium crystals for radiation detectors
輻射探測器用高純度鍺晶體的測試程序The above three monitoring systems are high purity germanium based or sodium iodide based to monitor the activity concentrations of the radionuclides in foodstuffs or drinking water rapidly
這三個監測系統是利用高純度鍺探測器或碘化鈉探測器迅速監測食水及食物中的放射性核素含量。High purity germanium detector
高純度鍺探測器We are used to gain the detection efficiency by making the standard samples, because of the different source of the environment samples, the component and density and volume of the samples ca n ' t entirely match those of the standard samples, so it is very difficult to make the standard samples, thereby, in order to conquered experiment difficulty, this article has calculated the detection efficiency of hpge - spectrometer by existing monte carlo code
但由於待測環境樣品的來源不同,其介質成份、密度和體積量可能相差很大,實驗上又難以製作各種各樣的標準樣品,採用蒙特卡羅方法可以比較容易地解決這些問題,對此,我們採用蒙特卡羅方法,研究了高純鍺譜儀對不同環境樣品的探測效率,解決了實驗上製作各種標準樣品的難題。In the radioactivity measure of the environment samples, hpge - spectrometer can expediently analyze the species and content of the radionuclide in the environment samples. those demands the detection efficiency corresponding to the different energy y - ray in the various environment samples
在放射性測量中,採用高純鍺譜儀可以方便地分析環境樣品中放射性核素的種類和含量,但要準確地分析核素含量,需要準確知道各樣品中的各種能量射線的探測效率,通常由一定密度和樣品量的標準樣品來得到這一效率。分享友人
