平衡点

According to the feature that the advantages and disadvantages of the three methods are supplementary to each other, a new method called"Synthetic Direct Method"has been proposed for fast direct transient stability analysis, which compositely uses the advantages of three methods and is fault tolerant and with higher accuracy and reliability.

本文重点对此进行了深入研究，主要工作如下：对常用三种直接暂稳分析算法，即：相关不稳定平衡点法、势能边界面法、扩展等面积准则法，从计算假定、计算精度、计算速度及可信度等多方面，在理论上及实际计算上进行了大量的研究和比较，分析了大误差发生的原因，并对方法作了改进和完善。

A genetic algorithm is used to optimize feedback gain matrix of all local linear sub-systems, which can ensure the correlate between local linear controllers and change gains continuatively and improve helicopter handling qualities.

对于直升机在整个飞行包络内得到的各个平衡点处的线性子系统，本文采用遗传算法对反馈增益阵进行优化选择，保证了各个子系统控制器之间的相关性，使得神经网络能够进行连续增益调参，改善了直升机的飞行品质。

Contrastingly, in the metapopulation models without Allee-like effects, neither high nor low habitat occupancy combinations would lead to extinction of both competitors.

似Allee效应很可能是两个集合种群竞争系统的一个不稳定因子，它本身可以使得两个集合种群的三个状态的竞争系统的平衡点增多。

Glenn Wilkinson is evidently leading a covetable life, having reached the balance point between work and leisure.

Glenn Wilkinson先生的生活为不少人所羡慕，显然，他在自然与工作之间找到了最佳的平衡点。

What balance we strike- whether we build on the blessings, and progress into an ever-increase of the good things on the positive side, or whether we magnify the miseries until our life sinks to what an old nurse of mine used to call a "depressingness" on the negative side-this issue can depend to a surprising extent on what spirits we create with words.

我们寻找着一个怎样的平衡点-是否寄希望于祝福，并且让它成为好事情层出不穷在好的一面，还是我们把灾难无限扩大化，直到生活消极地退步到我的一个老护士对所谓的&郁闷&状态-这在很大程度上取决于我们能够用语言创造出什么样的精神劲。

With the development of product placement in commercial movies,its powerful disseminative effects and wealth commercial value have been gradually profound understanding.

只有经过&否定之否定&的发展过程，植入式广告才能真正的发掘出在质和量上的平衡点，从而真正获得最佳销售效果和传播效果。

Based on the method of Filippov, we discuss the existence and geometrical properties of different types of equilibria.

利用Filippov方法，研究了系统中各种平衡点的存在性和几何性质，讨论了系统中多种闭轨的存在性，尤其是滑模闭轨和滑模同宿轨。

Suffcient conditions for the existence and exponential stability of equilibria of the networks are obtained.

得到了平衡点存在以及指数稳定的充分条件。

The basic reproduction number is established. Existence and stability of equilibria are studied with conditions only related to this number.

建立了模型的基本再生数，得到了平衡点的存在性和稳定性只依赖于此再生数。

In Lipschitz condition of the signal transmission functions, the uniqueness of the equilibrium for MAM is proved respectively by using M matrix properties and using homeomorphous map.

在信号传递函数满足李普希兹条件下，分别利用M矩阵性质及同胚映射证明了平衡点的唯一性。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
