In the mean time, i test the separator ’ s performance, including the rate of hole 、 the performance of absorbing electrolyte and the conductance eletrochemical steady range 、 machine intensity test, and then make bettery to test its cycle performance. the test result show that, the spreading separator get better performance, when dbp ’ s percentum reach 50 %, and dry temperature reach 90, after ultraviolet radiation disposal. the test show that, the separator has high conductance reach 6. 1 10 - 3s / cm ( 25 ), and the machine intensity can reach 3. 92 mpa, this separator can meet the need of making bettery, the bettery capability will go down after 30 cycle. and the bettery show worse performance under high temperature, under 70, the bettery will get fire. making the intensified seprator, i find that when dbp % : pvdf % = 40 % : 60 %, dbp % + pvdf % : sio2 % = 70 % : 30 %, the separator get
但用其制備的電池循環30周期后容量發生衰減，並且電池高溫性能差， 70下電池燃燒;強化聚合物膜的最佳制備配比條件為: dbp : pvdf為40mass % : 60mass % ， dbp含量與pvdf含量之和與納米sio2含量比值為70mass % : 30mass % ;強化電解質隔膜的室溫離子電導率也可達4 10 - 3s / cm左右，完全能滿足聚合物鋰離子電池的使用需要;機械強度遠遠大於流延法制得的隔膜，達到108 . 84mpa 。 -
5. there are 979. 32 meter long to the curtain of the xiangshuiriver reservoir include 879. 32 meter " s long double row curtain ( about 92 percent ) in the original design. by optimizing the design according to the grouting test, the double row curtain was cut down to 245. 66 meter length ( 25 per cent of them ), the density of the bore hole have from 0. 81m / m2 reduced to 0. 64m / m2. total save 4. 47 million rmb cost of the project
5 、在總長為979 . 32m長的帷幕段中，初設批復方案的雙排帷幕總長為879 . 32m ，占帷幕總長的92 % ，根據灌漿試驗研究成果優化設計后，雙排帷幕長度減少至245 . 「 m ，僅占帷幕總長度的25 % 。
