  1. 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。
  2. By means of trigonometrical progression method and the mainline track spectrum, the sample function of the chinese mainline railway track random geometric irregularity is simulated. with the data obtained from track geometry inspection car on qinhuangdao - shenyang special line for passenger transport and arma time series model, the sample function of high - speed railway track random geometric irregularity are simulated. based on existing literature, the artificial bogie crawl waves at various different speeds are randomly simulated
