For the tweeter,L3 acts as a shunt inductor and as an autotransformer to allow for differing levels of sensitivity.C2 is adjusted to keep the crossover frequency constant and R3 is there to prevent ringing,with R4 and C6 to adjust the frequency response at the upper end.

针对高音单体，L3的作用为一分流指示器与自耦变压器，以便区别灵敏度的等级。C2是用以调整保持分频点的衡定，而R3则用来避免铃振，并同R4与C6以调整高频端的频率响应。

Systematical researches were carried out on the cleavage strength of steel fiber concrete with 3 base strength grades,6 steel externalities and 4 fiber admixtures,and it is discovered that the cleavage strength of concrete increases as the base strength grade rises,and dumbbell-like,shield-like and hook-like steel fibers have good reinforcement effect while flat steel fiber has less reinforcement effect.

通过对3个基体强度等级、6种纤维外形、4种纤维掺量的钢纤维混凝土的劈拉性能进行系统研究，发现混凝土的劈拉强度均随基体强度等级增加而增大；哑铃、盾铃、端勾形钢纤维的增强效果较好，而平直形钢纤维的增强效果较小。

Reckon everybody has encountered, the message nodding a song of the 12590 and so on that hair of QQ good friend comes to, still have news of graph bell advertisement, also had encountered play a window indescribably, the Ie that goes be not being dropped installs home page to wait a moment, actually these are today the virus that I should tell, scampish end popularizes kind of client, although oneself very be fed up with method of this kind of promotion, but it also is a kind of promotion, make a simple introduction in this today.

估计各位都遭遇过，QQ好友发来的12590之类的点歌消息，还有图铃广告消息，也遭遇过莫名其妙的弹窗，去不掉的ie设置首页等等，其实这些就是今天我要讲的病毒、流氓类客户端推广，虽然本人十分讨厌这类推广方法，但它也是一类推广，今天就在这做个简单的介绍。

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。
