    針對可調型機械擋光衰減器的擋光特點，從衍射理論的角度分析和發現該器件的衰減特徵，並根據該特徵選擇擋光片，製作了衰減器。在傳輸光路上試用，獲得了較好的效果。
  2. 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 。
  3. The fva - uv is an opto - mechanical device that controls the amount of light transmitted between two optical fibers. internal disc varies attenuation from 0 - 100 %

    Uv是一個光學機械裝置，可控制在兩根光纖之間傳輸的光的數量，內部光片可在0 - 100 %改變衰減率。
  4. In view of this, the development of new - type optical switches have started, it can achieve the optical layer routing, wavelength selection, optical cross - connect functions, has great potential and broad prospects for application in the field of optical fiber communications market

    它的出現為光開關、光衰減器以及濾波器等光纖通信器件的微小型化、大陣列化和低成本化提供了技術上的可能性。因此微光機電系統（ moems ）是微電子機械繫統（ mems ）的一個很有前途的應用領域。
