  1. The tests of e - o applications by our flux ktp has been realized, the results showed : optical waveguides fabricated by using an ion - exchange process, which have an exchange - ion concentration depth profile and refractive - index profile, is close to a complementary error - function distribution, optical homogeneity and device thermal stability is much better. amplitude modulation switch formed by our flux ktp has the contrast ratio of 150 : 1 and insert loss is 2. 5 % at 1064 nm. high quality optical pulse with 1 ns width was cut successfully by using an e - o modulator from a laser pulse with 50 ns width, this modulator had run for three years, and the crystal did n ' t blackened, it showed our low conductivity flux ktp can endure high modulation voltage for a very long time

    Ktp晶體的電光應用試驗表明：用離子交換法製作的電光波導，其離子交換濃度、折射率變化符合餘弦誤差函數，光學均勻性以及器件的溫度穩定性較好；製作的強度調制電光開關，消光比為150 ： 1 ，對1064nm激光的插入損耗為2 . 5 ；製作的電光調制器用於激光脈沖整形試驗，從脈沖寬度50ns的激光脈沖削出脈寬1ns的高質量光脈沖，該電光開關經過長達三年多的使用，沒有出現晶體變黑現象，說明本實驗的低電導率ktp晶體能夠耐受長時間的調制電壓。
  2. Recently, kumar and gadagkar ( 2001 ) proposed a simple measure, disparity index ( id ), to quantify the difference in observed substitution patterns between molecular sequences, and use it to develop a statistical test as the probability distribution of this statistic ( id ) is unknown, monte carlo approach must be used to test the null assumption of homogeneity

    近來， kumarandgadgh （ 200 ）提出了一個簡單的測量一差異指針（ isparityindex ， id ）來量化這種在分子序列間觀察到的替代模型的不同，並用它發展了一個統計檢測。由於這個統計量峋）的概率分佈是未知的，故必須利用montecarlo方法來檢測這無效同質性假設。
  3. Results indicats that structural superposition index is a rational approach to measure the degree of structural homogeneity of manufacturing. types of indexes and datum have little influence on the degree of structural superposition of manufacturing

    研究表明，結構重合度指數是比較合理的測度製造業同構度的方法，而且不論使用哪種類型的數據，測算得到的製造業結構重合度並無顯著差別。
  4. In order to study the relationship between homogeneity and performance variation of asphalt mixture, based on digital image processing technology, using the regression method, the relationship between homogeneity of asphalt mixture and air void, dynamic stability and mechanical strength of asphalt mixture was quantitatively investigated via the index of homogeneity of asphalt mixture

    摘要為了研究瀝青混合料均勻性與性能間的相互關系，基於數字圖像處理技術，通過瀝青混合料均勻性指標，利用回歸方法對瀝青混合料均勻性與空隙率、動穩定度及力學強度間的相互關系進行了定量研究。
