单位圆

By the properties of k-th order symmetric function , we obtained some estimations of integral mean value of the solutions of the boundary value problems for some kind of special partial differential equations in Dk which can be changed into Laplace equations in the unit circle by way of suitable transform .

另外，D_k上的某一类特殊的偏微分方程经过适当变换后转化为单位圆上的Laplace方程，其边值问题的解的积分平均估计可由k次对称化函数的性质较好给出。

Networked control system is stable on condition that this circular area is in a unit circle.

若此圆形区域在单位圆内，网络控制系统就是稳定的。

The unit circle hides the wings of the distribution and even the median will generally result in biased estimates.

单位圆内隐藏的翅膀分布，甚至位数通常会导致偏见的估计。

The minimum phase system demand all zeros are within the unit circle.

所谓最小相位，要求所有零点都在单位圆之内。

The sign of a complex number finds the complex number of the same direction found on the unit circle.

一复数之符号数乃得出单位圆上，一个方向与原复数相同之复数。

Discrete-time Fourier transform is essentially the unit circle Z transform.

离散时间傅里叶变换实质上就是单位圆上的Z变换。

For the digital filter design problem, the mathematics are complicated by the approximation being defined on the unit circle.

数学问题中固有的频域滤波器设计的问题是逼近理想的复杂的频率响应函数的HD的一个合理的传递函数的H就一个Mth度的分子和一个第N次度标准值复杂的变量沿着单位圆的Z = ejw 。

Not only does it realize global optimization of objective function and quickly converge, but also increase the stability of the filter system, especially in the case where the poles of the filter system are close to the unit circle.

不仅实现了自适应非线性滤波的全局寻优和快速收敛，而且提高了系统的稳定性，尤其对于极点靠近单位圆的AR模型信号干扰，滤波性能有较大的提高。

In addition, such as control of land supply, control land mortgage loans, overdue development will revert to the land use rights, land market order rectification measures are directed at the land market weakness, particularly in the past through the edge acts under the land of the unit circle, the recovery of development rights, and strictly control land transactions loans of these measures to rectify the land market would be tantamount to an ultimatum.

此外，如控制土地供应，控制土地抵押贷款，逾期将再向发展的土地使用权，土地市场秩序整改措施是针对土地市场疲软，特别是在过去通过边缘行为根据土地的单位圆，收回开发权，严格控制土地交易贷款这些措施，纠正土地市场就等于最后通牒。

By mellin transform the properties of Toeplitz operators on the weighted Bergman spaces of the unit disk are studied in the third chapter.

第三章利用Mellin变换研究了单位圆盘的加权Bergman空间上Toeplitz算子的性质。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
