並認為三者相互聯系，相互依存，從始自終貫穿于國際環境犯罪的打擊和預防行動之中，對國際社會打擊和預防環境犯罪的具體對策起著指導性作用。Simulation of water pulse forming line switch with prepulse suppression ground plane
具有預脈沖屏蔽板的水介質自擊穿開關的電路模擬( 3 ) volume shrinkage of composite decreases greatly with wpu increasing, even can arrive a negative number, but thermal stability is still good. ( 4 ) toughening mechanism is that : the formation of high molecular linear amino formate construct is the toughening reason ; hydroxyl - terminated pu - prepolymer and pf react to produce chemical bond effect which participate cure ; carboxyl - terminated pu - prepolymer and pf form semi - ipn which make toughened pf occur maximum
（ 4 ）通過紅外光譜對pf / pu共混物分子結構進行的定性分析、以及掃描電鏡對沖擊斷面形貌進行的分析，可證明聚氨酯預聚物增韌酚醛樹脂的機理是：兩個體系都是由於高分子量的線形氨基甲酸酯結構而增韌；端羥基pu與pf在共固化中產生化學鍵效應，參與pf的固化；而端羧基pu則與pf形成半互穿網路而增韌。When the voltage exceeds the breakdown strength for a given insulation system, undesirable conduction paths will be created and the system will be either temporarily or permanently disabled
當電壓超過確定絕緣系統的擊穿值時，將出現預料之外的電流路徑而且這個絕緣系統將暫時或永久地停止作用了。Abstract : a previously proposed approximate quasi - static theoretical method is employed herein to examine the deformation and perforation of a simply - supported circular plate struck by a flat - faced projectile at normal incidence. based on the principle of virtual work, static load - displacement relationships are first obtained and then used to predict the energy - absorbing capacity of the plate subjected to relatively low speed impact. it is shown that good agreement is obtained between the theoretical predictions and the available experimental data, provided that adiabatic shear plugging failure does not occur, but the influence of strain rate sensitivity is taken into account
文摘:採用準靜態近似理論方法分析簡支圓板在平頭彈丸正撞下的變形和穿透.首先基於虛功原理得到了靜態荷載位移關系，並將其用於預測低速沖擊下圓板的能量吸收能力.當考慮了材料的應變率敏感性，並且不發生絕熱剪切沖塞破壞的前提下，理論預測和實驗結果吻合良好Abstract : the saturation behavior of stress current is studied. the three types of precursor sites for trap generation are also introduced by fitting method based on first order rate equation. a further investigation by statistics experiments shows that there are definite relationships among time constant of trap generation, the time - to - breakdown, and stress voltage. it also means that the time constant of trap generation can be used to predict oxide lifetime. this method is faster for tddb study compared with usual breakdown experiments
文摘:基於一階速率方程，討論了恆定電壓應力下應力電流的飽和行為.通過對應力電流的擬合，發現存在三類缺陷產生的前身.更進一步的統計實驗顯示，在缺陷產生時間常數、擊穿時間以及應力電壓之間存在著明確的關系.這意味著缺陷產生時間常數能夠被用於有效預測氧化層的壽命.與常規的氧化層擊穿實驗相比，基於缺陷產生時間常數的預測更快、更有效According to calculation, synchronous closing can reduce the value of over - current and over - voltage in the closing transient process. the closing of capacitor is taken as an example to analyze movement process of synchronous closing. it also analyzes the impact of pre - strike characteristic, environmental temperature and control voltage on synchronous closing
通過計算分析了同步關合技術對合閘暫態過程中過電流和過電壓的抑制作用，並以電容器的同步關合為例，分析了同步關合的動作過程及預擊穿特性、環境溫度，控制電壓等外界因素對同步關合技術的影響。分享友人
