Aimed at the problem of choosing the initial value when the Newton method is used to compute the controlling unstable equilibrium point, a practical and rigorous solving scheme was presented: by identifying the controlling load bus of the given fault, and using the Thevenin equivalent circuit to represent the rest of the system at the state of the post disturbance stable equilibrium point, using the steady equivalent circuit to represent the induction motor in composite load, and then using the torque characteristics of induction motor, a point near the CUEP is gained to be the initial value. The second order normal forms was used to approximate the stable manifold of CUEP, and the local approximating boundary of the region of attraction of the post disturbance stable equilibrium point was gained. Then just by simulating the state of the system at the fault clearing time, the transient voltage stability of the system could be determined.

针对采用牛顿法求取故障后系统主导不稳定平衡点(controlling unstable equilibrium point，CUEP)存在的初值选取难题，提出一种实用但不失严谨的解决方案：通过识别给定故障的主导负荷母线，对主导负荷母线以外系统由故障后稳定平衡点处的状态进行戴维南等值，对负荷中感应电动机部分采用其稳态等值电路，再由感应电动机的转矩特性求得CUEP附近的一个点作为近似的CUEP，以此为迭代初值可靠求得CUEP；采用二阶正规型来近似CUEP的稳定流形的方法求得近似的局部吸引域边界；由仿真得到故障清除时刻系统的状态并根据该状态是否位于吸引域内判断系统的暂态电压稳定性。

The practical value of this kind of thick and heavy iron Jian is more similar with Dao,and swordman won't use it.

此类厚重铁剑的实用价值与刀更相近，武术剑客是不会用这类剑的。

A highly successful interlude as the Lucerne festival's artiste étoile in 2007 and a Messiaen retrospective in London last year proved that Mr Aimard enjoys unrivalled connections with leading European composers and performers and has an attitude to music-making that is highly pragmatic while still uncompromising.

2007年琉森音乐节"艺人之星"，去年伦敦的梅湘再现，毋庸置疑，艾马尔已跻身欧洲作曲家和表演者之列；这也表明他的音乐制作态度高度实用而不肯妥协。

He is as beautiful as a (6)weathercock," remarked one of the Town Councillors who wished to gain a (7)reputation for having artistic tastes;"only not quite so useful, he added, fearing lest people should think him (8)unpractical, which he really was not.

有一位市议员想要表现出其高尚的艺术品味，而对雕像提出他的评论，「快乐王子就像风向标一样漂亮啊！」，不过说完之后，又怕人们会认为他太不切实际──况且他实际上也不是这种人，於是连忙补上一句，「不过呀，没有风向标那麼实用就是了！

Utility applications are visually attractive, but in a way that enhances the information they display without overshadowing it.

实用程序有吸引人的视觉效果，在某种程度上，这种效果加强了信息的呈现，而不是遮蔽呈现。

Normal rotor rpm 233, severe vibration, and though positive control never lost, stick force and phugoid instability worsened beyond 30km/h forward speed, severely limiting practical value of EG.

正常转子转速233，剧烈震动，阳性对照，虽然从来没有丢失，粘力和phugoid不稳定恶化超出30公里/小时的速度向前，严重限制了乙二醇的实用价值。
