  1. Absolute isotopic abundance measurement

    絕對同位素豐度測量
  2. In order to meet the requirements of nda measurement, the laboratory of technical research for nuclear safeguards of china institute of atomic energy ( ciae ), is being in charge of developing four sets of nda standards : one set of segmented gamma - ray scanner ( sgs ) uranium standard, one set of sgs plutonhim standard, one set of plutonium isotopic standard, and one set of active well coincidence counter ( awcc ) standard. in this dissertation some pivotal techniques on quality control in developing of nda nuclear standards above were emphatically studied

    中國原子能科學研究院核保障技術重點實驗室研製分段y掃描裝置（ sgs ： segmentedgamma - rayscanner ）鈾工作標準樣品、 sgs鈈工作標準樣品、鈈同位素標準樣品和有源中子井型符合計數裝置（ awcc ： activewellcoincidencecounter ）鈾工作標準樣品來滿足核材料nda測量的要求。本論文重點對上述nda核標準樣品研製過程中質量控制的一些關鍵技術進行了研究。
  3. With the corrected parameter files, the results indicate that the isotopic abundance in the sample can be determined within 2 % error using a hpge detector system. artificial neural networks ( ann ) are a class of models based on neural computation and have been applied to the measurement of uranium enrichment. the principles of ann methods used in uranium measurement are presented in this paper and the conditions of analysis proceedings are described

    在核保障核查測量中和實物監測中，測量對象往往是規格確定並種類有限的元件或部件，只需要關心測量對象的屬性是否發生了變化，或者對同一種類的放射性樣品的一致性做出判斷，這種要求下使用神經網路方法是比較適宜的，並且神經網路方法是與探測器和探測效率無關的。
  4. 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。
  5. Separation of boron by using ion exchange technique for the isotopic measurement of boron in salt lake brine

    鹽湖鹵水硼同位素測定中硼的二次離子交換分離
  6. The isotopic composition of lead often varies from one source of common copper ore to another ， with variations exceeding the measurement error ； and preliminary studies indicate virtually uniform is topic composition of the lead from a single copper - ore source

    鉛的同位素構成經常在一種普通銅礦石來源與另一種銅礦石來源之間存在差異，其差異程度超出測量誤差；而最初的研究表明，對于來自單獨一個銅礦石來源的鉛來說，其同位素構成幾乎是毫無二致的。
  7. The application research on the isotopic tracing flow measurement using cross correlation technique

    互相關技術在同位素示蹤流量測量中的應用研究
