The original defined adakitesare sodium igneous rocks, they are tonalite, trondhjemite or (plagioclase-rich) granodiorite in whole-rock chemistry; however, the K-rich "C-type" adakite defined by Chinese scholars are potassic igneous rocks, they are granite, quartz monzonite and (alkali feldspar-rich) granodiorite, etc.

Two kinds of silicon samples with distinct surface treatment, i. e., one surface was chemically etched and the other was unetched, were used to investigate the characteristics of leakage current and surface flashover of semiconductor under impulse voltage in vacuum. The experimental results showed that the surface conditions of samples affected these characteristics greatly. Before flashover, the Ohmic current was observed for unetched samples and the space charge limited current for etched samples, respectively. Meanwhile both samples showed quite different flashover tracks, and the surface-etched samples displayed a much higher onset voltage of flashover.

对采用和未采用表面化学腐蚀处理的半导体硅在冲击电压下的实验表明（参见 Zhang et al ， Applied Physics Letters， 2002），试品的表面状况对其泄漏电流和沿面闪络特性有着很大的影响：在沿面闪络之前，未经处理试品的泄漏电流表现为 Ohm 性电流，而表面处理过的试品表现为空间电荷限制电流特性；同时两类试品表面的闪络通道也表现出不同的特征，而采用表面化学腐蚀处理可以明显提高其沿面闪络电压。

The ALK of the fine dioritequartz diorites is 5.47%~5.88%, ratio of K2O/Na2O is 0.455~0.496. Therefore, it belongs to calcalkalic rock series and shows the characters of Ⅱtype Adakite; The ALK of dioritic porphyritedacite porphyries is 7.83％~8.28％, ratio of K2O/Na2O is 1.100~1.747, belonging to shoshonitic rock series.

细晶闪长岩-石英闪长岩的ALK值为5.47％~5.88％，K2O/Na2O值为0.455~0.496，属钙碱性岩系，并具有Ⅱ型Adakite岩的性质；闪长玢岩-英安斑岩的ALK值为7.83％~8.28％，K2O/Na2O值为1.100~1.747，属粗安岩系。

The analysis of leakage causes for flash trough was presented, and the wear layers on inlet tube and the baffle wear plate inside of flash trough were used to increase the wear life of flash trough.

分析了闪蒸槽泄漏的原因，采用在进口接管堆焊耐磨层及筒体上增加耐磨档板的方法对闪蒸槽进行了改造，增加了闪蒸槽的寿命。

Complex cross-feed and parallel-feed multi-evaporation systems for conventional design was first established to lucubrate on disciplinarian and influential factors of multi-evaporation. In this model, the energy-saving measures, such as extra steam being led off to preheat material liquid, the condensation water flash and solution flash, were adopted. The solid separation was also considered in the process of evaporation and solution flash.

为了更充分合理地利用能量以及深入研究多效蒸发过程的规律和影响因素，采用引出额外蒸汽预热原料液、冷凝水闪蒸、溶液闪蒸等节能措施，考虑蒸发过程及溶液闪蒸过程有固相析出的情况，首次建立了复杂错流、平流多效蒸发系统常规设计的通用数学模型。

In addition, the flash point in the spy must be noted that the pace of opening to get faster, when you came bunker, even if your heart with the goal of quasi-poor months thousands of miles away, it must be the first time off guns, Regardless of hit or not, immediately flash back bunker, if you are in life, then adjust the location of the prospective heart, ready to attack next.

另外，闪狙中有一点一定要注意，就是开抢的速度一定要快，当你闪出掩体，就算你的准心与目标差个十万八千里，也务必要第一时间甩枪，不论打中与否，马上闪回掩体，如果你还有命在的话，调整准心位置，准备下一次攻击。

Laboratory investigations on the flashover performances of polluted five types of typical porcelain and glass insulators were carried out in the climate chamber. Based on the test results, this paper analyzes and calculates the flashover voltage, the voltage gradient and the valid creepage distance of the five types of insulators.

Ambient exposure is unaffected. This can always be set on the flashgun itself, but some cameras have a button on the camera body itself where the flash compensation can conveniently be set without taking your eye from the viewfinder.

闪灯曝光补偿一般需要在闪灯上设置，但有的相机在机身上提供了一个按钮来设置闪灯的曝光补偿，这样你就可以眼睛不离开取景器进行曝光补偿的设置了。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
