扰动

Deimos and Phobos may be due to disturbance of asteroids and Jupiter's role was to make them around Mars movement.

火卫二和火卫一可能是由于小行星的扰动与木星的作用才使它们围着火星运动的。

The characteristics of changed Sr/Ba coincide with particle size and macroelement analysis. The higher Sr/Ba shows depauperization and increasing salinity.

Sr／Ba值的升降变化特征与粒度分析结果和常量元素分析结果都十分吻合，底部的高值说明湖面萎缩，盐度增加；56cm（公元1923年）以下相对平稳，56cm以后出现剧烈波动，这是人类活动对环境扰动的结果。

Results show that the combustion of igniter is disturbed violently by the rapid depressurization.

结果表明，在高速降压过程中，底排点火具燃烧受到强烈瞬态扰动。

When this disturbance occurred, you may, if science is advanced enough at the time, put a depth charge into it and disrupt the flow of time.

当这个扰动发生的时候，你可以---如果此时科学足够发达的---放进一个水雷，来干扰时间流。

A PID-like cost function is proposed, and it can be proved that the PID algorithm is the gradient descent method as long as the cost function is selected as ours.

这种新颖的控制器算法具有自适应功能，原因是控制律中引入了被控对象的灵敏度，从而提高整个控制系统在参数变化及受到负载扰动时的鲁棒性。

He said the government would combat any attempts to destabilize the country.

他说政府会和任何扰动国家的试图做斗争。

Perturbation analysis is an efficient method to study DEDS, whitch requires the differentiability of the performance function.

摘要扰动分析是研究离散事件动态系统的有效方法，性能函数的可微性是应用该方法的前提条件之一。

This paper develops a new design method of self-tuning pole placement controller. In this method, parameters of the controller can be directly obtained by a two level linear identifier. It is unnecessary to find the solutions of Diophantine Equation and identify the extra auxiliary parameters. At the same time, the effect of deterministic disturbances can be eliminated.

提出了一种极点配置自校正控制器的设计方法，这种方法用两级线性辨识器可直接获得控制器参数，无需求解Diophantine方程，也不需要辨识多余的辅助参数，而且可以消除确定扰动的影响。

In this beamline, with the neutron depolarization technique, provides information of the mean domain size, the mean square direction cosine of the magnetic induction in the domains, and the mean magnetization of a magnetic sample.

三维去极化中子仪主要为观察极化中子通过磁性材过程，受到内部磁区的扰动使得极化中子向的方向和大小改变，进分析后可以观察出材内部平均磁区大小、平均感应磁场强、磁区平均方向余弦的平方。

Using the directional derivative formula, the governing equation is discreted in the physical domain in which a nonorthogonal grid system is used. Two kinds of AF2 schemes, i. e. AF2-plane relaxation and full implicit AF2, for the TSD equation are proposed. Numerical results show that the full implicit AF2 scheme converges faster than AF2plane relaxation scheme. For the rectangular wing and swept wing, the results of the present method are compared with FP results, and the agreement is good.

采用适合于梯形机翼和后掠机翼的斜网格，利用方向导数公式直接在物理空间对主管方程进行离散；将近似因式分解方法应用于绕机翼的跨音速小扰动势流问题，提出AF2—面松弛和AF2全隐式两种迭代格式，并对它们的收敛速度进行比较，结果表明后者明显快于前者；直机翼和后掠机翼的算例表明，本文方法的结果与精确势流方法的结果吻合良好。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
