Although violation of homogeneity assumption is known to adversely impact the accuracy of phylogenetic inference and tests of evolutionary hypotheses, testing such the assumption has been little investigated to date
盡管違背了這個假設就相對地影響了系統發生的推論和進化假設測驗的粘度，但檢測這個假設卻鮮見研究。 -
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。 -
