不变

The rezults show that this kind of superplasticizer not only has high dispersibility, but also has the possibility to controlling slump lost.

结果表明，这类高效减水剂除具有很高的分散性(减水率达30%)外，还具有控制坍落度损失的功能(2小时内坍落度基本不变)。

Dissolving, there are some tens of millions who want Christmas

圣诞节还是那个古老的，不变的圣诞节。

Concerning the distortionless linear transmission system,a new method-SSPD was put forward,which implements the precise time delay through a linear shift invariable system with unit impulse response symmetry.

从无失真线性传输系统的角度，提出了基于具有对称特性的单位冲击响应的线性移不变系统实现精确时延的方法——SSPD。

By means of the projection method,adding a small disturbing function to the objective function, the penalty method, andthe gradient method, this dissertation proposes several neural networks for solvingsaddle point problems and minimum radius of ball-coverings problems, and investi-gates the stability of the proposed networks by the LaSalle invariance principle andthe Lyapunov method, so as to design neural networks which avoid getting stuck inthe local minimum.

本文针对约束鞍点问题和球覆盖最小半径的计算问题，分别利用投影法、对目标函数加上很小"扰动函数"的逼近法、罚函数法和梯度法等建立神经网络模型进行求解，并基于LaSalle不变集原理和Lyapunov直接法等工具，对模型的动态特性进行研究，从而设计出避免陷入局部极小的优化计算神经网络模型。

But he would get on and sing this song"I wish that i were married."at the top of his lung and then pull a Dixie cup out from under the windbreaker he always wore and walk up and down the car waiting for contributions.

但他会上来唱这首"我希望我已经结婚了"，并且在唱到最高音的时候从他经久不变的防风外衣里掏出一个装饮料用的纸杯，然后沿着车厢来回走动，希望能得到一些小费。

She, always constant of, is still the heart of that docile!!!

她，始终不变的，仍是那颗善良的心！！！

Both controllers consist of linear output feedback and nonlinear feedback, resulting in a closed-loop system with asymptotic stability in the invariant set inside the domain of attraction.

控制器由线性输出反馈项和非线性反馈项组成，使得闭环系统在包含于吸引域的不变集内渐近稳定。

You are comfortable with responsibility because you are capable of getting others to follow you without becoming domineering and dogmatic.

你能很舒服地应付责任，因为你有本事让别人跟随着你，而且又不变得专横跟固执。

The nature of the domino theory shifted over time, but the core claim remained the same: If Vietnam were allowed to "fall," other countries would swiftly follow suit, thereby allowing Beijing and its ally in Moscow to consolidate Communist control over the region, and ultimately over much of Asia.

随着时间的流逝，多米诺理论的特点也在发生变化，但是其核心不变：如果任越南"沦陷"，其他国家很快将会步其后尘，从而使北京和其在莫斯科的盟友巩固共产主义对该地区的统治，并最终控制亚洲大多数地区。

To advocate the right doxy with unchanging mind.

以不变的心坚持正确的理念

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。
