查询词典 disturbances

To the single axis control model of the stabilized platform, the sliding mode rule is founded. The value of extraneous disturbances is estimated by using GM (1, 1) grey prediction algorithm, and then it is added to the sliding mode control rule as the compensating part. At the same time, the value of the switching function is predicted by the grey prediction method, by which the control chattering phenomenon is reduced greatly.

基于稳定平台的单轴控制模型，设计了滑模控制律，采用GM(1，1)灰色预测算法估计扰动量，将其作为控制律中的补偿分量，同时应用灰色预测方法对滑模控制策略进行预测输出，有效地减弱了滑模控制的抖动现象。

In this dissertation, solar chromosphere-corona models are extended to spherical geometry for the first time. By using time-dependent, compressible MHD simulation, we numerically study, either 2-dimensionally or 3-dimensionally, the local and global propagation processes of the disturbances in solar atmospheric models.

In order to simulate the global characteristics of wave propagation in solar chromosphere-corona, by employing a 2-dimensional MHD simulation subjected to a self-consistent non-isothermal, non-uniform initial state in spherical geometry, we study numerically the global propagation process of disturbances initiated by a pressure pulse implemented at the bottom of chromosphere.

在球坐标中一自洽的非等温非均匀等离子体初态下，应用二维理想磁流体动力学全球模拟，对色球底部压力脉冲引起扰动传播的全球问题进行了数值研究。

But, oh! my young friend, what disturbances I find this springtide!

可是，哦！我年轻的朋友，今年春天我看到这里怎么那么地不安哪！

Star fruit ingestion has previously been reported to cause severe neurotoxicity in chronic renal failure patients, with symptoms ranging from hiccups, vomiting, and consciousness disturbances to refractory status epileptics, coma, and death.

慢性肾功能不全患者服用杨桃，在过去就曾被报告过造成严重神经毒性，症状从打隔、呕吐、意识混乱、到顽固性癫痫、昏迷、死亡。

This paper is concerned with two problems: First, a formula is derived to estimate the error of system identification from the autoeorrelative function of stationary random disturbances and that of pseudo-random sequences. It can be used to select the type of pseudo-random sequences to be used for quick identification with a given error.

本文讨论了两个问题：(1)导出了平稳随机干扰的自相关函数、伪随机序列的自相关函数和系统脉冲响应辨识误差之间的定量关系式，可用来选择伪随机序列和估计试验误差。
