  1. Because the concentration of zirconium in uranium has large ranges, from 1. 50xlo ' 6 - 3. 8g / gu, not only how to decrease the remainder of uranium to eliminate its determinate effect but also how to acquire higher recovery of zirconium is considered, so the method of silica gel, the method of tbp levextrel resin chromatography, the method of tta chromatography and the method of tta extraction are compared. then tta extraction is chosen to acquire the ideal separation purpose. compared with icp - ms and icp - aes, xrf has characters of high repeatability, stability, low cost, high concentration elements analysis, the ability to determinate solid sample and having comprehensive practicability, but xrf has lower sensitivity, so how to increase the concentration of the sample to acquire better precision is a difficult problem, the optimum of operating condition : the integral time of spectral lines is 60s, the integral time of background lines is 20s, the voltage of xrf is 50kv, the electric current is 50ma

    由於鈾中鋯的含量范圍很廣，從1 . 50 10 ~ （ - 6 ） 3 . 8g / gu ，在分離和測量時，既要考慮盡量地減少鈾的殘留量以消除鈾對鋯測量產生的影響，又要獲得鋯的理想的回收率，因此本文在分離方法的選擇上比較了硅膠吸附分離法， cl - tbp萃取色層法， tta萃取色層法和tta萃取分離法的優缺點，認為tta萃取分離法可以達到理想的分離效果。
  2. The sample with low emitter efficiency has completed as the method of above. this lead to the greatly decrease of the reverse recovery time and the low reverse leakage and forward voltage, especially the excellent temperature character of the leakage. the test date shows that the samples reach the first class of international level

    本論文作者通過模擬測試，驗證了課題研究的理論設想，並設計製作了具有低陽極發射效率結構的高壓功率frd ，利用局域鉑摻雜和電子輻照相結合的壽命控制方式，實現器件反向恢復時間的極大減小，並且反向漏電流、軟度因子、正向壓降等關鍵參數也較理想，且具有極佳的漏電溫度特性，達到器件綜合性能的優良折衷，達到國際先進水平。
  3. This paper relates a study of using automated gel permeation chromatography ( gpc ) to clean soil sample extracts with an average recovery of spiked blank samples of about 79. 0 %, far better than the common florisil method

    將該凈化方法應用於實際土樣的凈化，並和佛羅里硅土凈化方法相比較，經凝膠滲透色譜凈化的20種有機氯農藥空白加標的平均回收率為79 . 0 % ，比佛羅里硅土凈化的空白加標平均回收率高14 . 9 % ，且凝膠滲透色譜的凈化效率較好。
  4. The recovery can reach 95 % after it extracts once, rsd % is lower than 10 %, the detection limit of zirconium is 1. 3u. g / ml. and increasing the application of film in xrf is studied. the method of using organic sample to make resource after extracted by tta can be used to determine zirconium in simulated p rocess solution of spent fuel reprocessing quickly and veraciouly

    萃取一次便可達到理想的萃取效果，回收率可達95 ，相對標準偏差10 ，鋯的檢出限為1 . 30 g / ml ，同時改進了薄膜法在x射線熒光光譜法中的應用范圍，此方法採用tta萃取分離的有機相直接制源可快速、準確地對測定purex模擬工藝料液中的鋯含量。
