解釋
瞄準南半球-
This system has two modes : automatic, manual. under the automatic condition, when the system detect that there is fire happening, the system will turn off blower, switch on valve and pump, and extinguish the fire if no people deal with the fire in the set time after the audible and light. under the manual condition, the operator can extinguish fire in the appointed area by the button in the main controlling panel or the manual button box ( locale )
在自動方案運行情況下，當系統檢測到有火災情況發生時，在發出聲、光報警后的一定時間，如果無人干預，則系統自動執行關閉風機、開閥、開泵，對火災區域進行水霧滅火；而在執行手動方案情況下，操作人員可以通過操作主控制屏上的按鈕或手動按鈕（現場）來對指定的區域進行噴灑滅火。 -
Since the departing process of fire work departing installation is a highly nonlinear transient dynamic process, it relates to many speciality field, and the characteristic of the material is very complex under the highly rate and highly pressure distortion, the design methods and the design formulae by experience which has been used for a long time are very limited, the facter which truly affect the departing process of fire work departing installation cannot been reflected in the design calculation, the structure modelling and optimization of the fire work departing installation is cannot been carried out by the traditional optimization method
由於火工分離裝置的分離解鎖過程是一個高度非線性的瞬態動力過程，涉及多個學科和專業領域，而且材料在高速高壓條件下瞬時性態十分復雜，長期以來所沿用的經驗設計方法和設計經驗公式的局限性很大，對火工分離裝置分離解鎖過程一些實際有影響的因素不能定量地反映到設計計算中來，採用傳統優化方法無法實現火工分離裝置的結構優化建模和計算。 -

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 。 -
