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。
