击穿

This paper gives out the principles and improving schemes of transformer discharge equipment and resonance booster discharge equipment. By detecting the current in the main circuit, the gap's breaking-down can be identified, and the single chip micro-computer will send out corresponding control signal to make the IGBTs to switch off or cut off the input voltage, by this mean, we can make sure that every time of the experiment, the sample will discharge only once. The paper also introduces the principle of the protection circuit. At last, the experimental waveforms were listed, which prove the feasibility of the high voltage discharge fast switch-off device.

该文给出了变压器和谐振升压器2种高压放电试验装置的原理以及改进方案，通过检测主回路电流大小判断间隙是否被击穿，由单片机发出相应控制信号，采用IGBT等开关器件控制试验电压的通断，保证了试品每次试验只进行一次放电，介绍了保护电路的原理，给出了试验波形，证明了此高压放电速断装置的可行性。

METHODS: Male Brown Norway rats were anesthetized to receive Nd:YAG laser to break the Bruch's membrane.

雄性Brown Norway大鼠，麻醉下行Nd：YAG激光击穿Bruch膜。

The results indicate that the breakdown voltage of BVLD device is increased by 94% in comparison to conventional LDMOS.

结果表明：与常规LDMOS相比， BVLD结构的击穿电压提高94％。

During the process of electrical breakdown, the carbonization degree is very large and drastic chemical reaction takes place.

电击穿过程中，炭化的程度非常大，介质发生了剧烈的化学反应。

"Exception No.1: A unit having resistive circuity , high-impedance winding , and the like , not subject to excessive secondary-voltage build-up in case of electrical breakdown during the test may be tested :"

"例外1：具有电阻性电路，高阻抗绕组以及类似物在测试时由于电击穿可能产生过高次级电压的电源单元，可以按下列方法试验："

By analyzing the investigated model,we can found that restriking phenomena occur which cause arc channel commutate to the contact region.

对断路器测试分析发现，这一现象是由电弧通道转移至触头区引起，而造成电弧通道转移的主要原因是发生在触头区的重击穿现象。

Meanwhile, the production theory and effect from continuous background of the plasma spectrum was analyzed, finally, the LIBS experiment system was described detail.

同时，分析了等离子体光谱连续背景的产生及其影响，最后详细描述了试验工作中搭建的激光感生击穿光谱实验系统。

In this case, the rapping acceleration is independent of ρ×J. From this new point of view, a critical rapping acceleration equation can be given based on the correlation curve of ρ and J presented by Oglesby.

从这一新观点出发，根据Oglesby提供的粉尘层击穿前的电晕电流和粉尘比电阻的相关曲线，得出临界振打加速度计算式。

"Yeah,When a bullet cut through our heart......"

"当然！！当一颗子弹击穿我们的心脏的时候。。。。。。。"

The electric field induced decomposition of ITO and electromigration of indium are responsible for the catastrophic failure, or thermal breakdown, of OLEDs. 5. Because of the importance of Si-based optoelectronics, We use p-type Si instead of ITO as the anode to fabricate OLEDs.

通过观察我们可以判定OLEDs器件的热击穿是由于其内部形成了严重的短路，而在高的正向驱动电压下器件严重短路的原因是器件内部本身存在的不均匀和ITO电极在高电场的作用下分解出的金属In沿着这些不均匀的位置在有机层电迁移扩散。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
