系统发生

These changes are called bifurcations. If bifurcations or even a versal unfolding are given, all physical phenomena of this system are clear.

弄清了系统的分岔甚至给出了它的普适开折，该系统所发生的所有物理现象都将昭然若示。

On the basis of analyzing the law of variation of the zero order current, the zero order voltage and the zero order power in the isolated neutral system, a synthetic criteria principle of selecting the grounded fault line according to three criterias at the same time was put forward.

1中性点不接地系统零序电流的分析中性点不接地系统在发生故障时零序电流的变化最明显，因而对故障情形下零序电流的大小、相位及其功率等关系进行分析很有必要。1.1零序电流的大小关系对于NUS，其线路图见图1。图中kl和k：断开。

Ageratina adenophora is a worldwide noxious weed and has caused tremendous detrimental effects on agriculture, forestry, rangeland and natural ecosystem since it invaded in Southwesten China in last century.

入侵我国西南地区的恶性杂草紫茎泽兰Ageratina adenophora(Sprengel对农业、林业、草场牧场以及自然生态系统带来了严重的危害，常导致入侵生境生态系统结构和功能发生改变，降低生物多样性且造成巨大的经济损失。

Ecological control of sludge bulking is highly important, especially in preventing sludge bulking through ecological relationship such as prey and autoeciousness of microorganisms.

指出丝状菌污泥膨胀的实质是活性污泥微生态系统平衡失调，微生物群落结构与功能发生变化，丝状菌种群代替菌胶团菌群成为优势种；利用微生物种群之间的捕食、寄生等关系控制污泥膨胀的生态学调控方法，是实现控制丝状菌污泥膨胀，保持污泥微生态系统稳定，获得良好污水净化效果的治本之法。

Our research work is currently focused on the molecular mechanisms of vascular cambium periodicity regulation and secondary xylem development, including cambial cell differentiation, secondary wall formation and programmed cell death.

本实验室以杨树、杜仲等树木作为实验材料，采用剥皮再生创伤系统和整体系统，研究维管形成层活动周期调控及形成层发生、次生木质部细胞分化、次生壁形成和细胞程序死亡的分子机理，为定向改良木材材质提供理论指导。

As to the dynamic loads, the calculation considers only the inertial loads because of jump-start and brake. However, in the actual turn-over processor of the circumgyrate machinery, especially in the process of braking, the impact to the organization is very obvious. Now in the strength calculation of the circumgyrate machinerys parts, this distinct dynamic effect is replaced by safty coefficient.

然而，在回转机构实际的运转过程中，特别是在制动时，机构中发生的冲击振动现象十分明显，但这种非常显著的动态效应在回转机构的强度计算中仅由安全系数来考虑，也就是把较复杂的动态系统人为地转化为简单的静态系统并没有准确地反映事物的本质。

结果 发生副作用共1 622例，占79 82%，其中消化系统反应1 030例，占50 68%；神经系统反应516例，占25 39%；呼吸系统反应11例，占0 54%；心血管系统48例，占2 36%；其他系统反应17例，占0 8%。

And it is essential to detune the pump and Stokes lasers so that one of the dressed intermediate states is on resonance, leading to the reduction of the whole system to the three-level system

调谐pump激光和stokes激光，使其中一个缀饰中间态发生共振，则可以使这个四能级系统简化为三能级系统。

The Ectasia Risk Score System is a valid and effective method for detecting eyes at risk for ectasia after LASIK and represents a significant improvement over previously utilized screening strategies.

角膜扩张风险评分系统是一个合格有效的检测方法，它可以检测出LASIK术后有发生角膜扩张风险的眼睛。与以前采用的筛查策略相比，该系统表现出明显的进步。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
