In this paper, a survey on this image segmentation technique is given and the performances of three basic graph partition algorithms (minimum cut, normalized cut and isoperimetric segmentation algorithm) are introduced and compared.

本文首先概述了图分割技术，介绍并比较了三种基本的图分割算法(最小割法，归一化最小割法和等周分割法)。

In this paper was obtained minimum point of sums of distances to isosceles triangle certainly was in median line of base of the triangle,and minimum point of quadratic sums of distances to every vextex in general triangle just was bara-center ofthe triangle.

对等腰三角形，得到了到各顶点距离之和的最小值点必在底边的中线上；对一般的三角形，获到了到各顶点距离平方和的最小值点就是三角形的重心。

The relationship between minimal model characteristic value of electric power system tie flow Jacobin matrix and voltage steady-state stability is was discussed, and the minimal model eigenvalue is was defined as voltage stability abundant degree. On this foundation, the sensitivity of voltage stability abundant degree to control variables and to PQ point load are was defined in order to seek the factors of impacting voltage stability and explore the voltage weak point, and give out their algorithm simultaneously.

讨论了电力系统潮流雅可比矩阵最小模特征值与系统电压静态稳定性的关系，将最小模特征值定义为电压稳定裕度，在此基础上定义了电压稳定裕度对控制变量的灵敏度和PQ节点负荷灵敏度，用以找出对系统电压稳定性造成影响的因素和寻找系统电压薄弱点，同时给出了它们的算法。

In other words, the threshold is set not only based on a relative level of jammer and noise but also the number of the jammed frequencies.

具体来讲，Clipper门限的优化是在最小信干比，同时受干扰的频率个数一定时系统误码率最小的条件下进行的。

By qualitative analysising, all lateen dangerous factors of VCM spheroid fired blast ed accident are identificated and the dangerous grades are definited.

通过定性分析，辨识了VCM球罐发生火灾、爆炸事故的潜在危险因素，确定了相应的危险等级，然后以"VCM储罐火灾、爆炸"为顶事件建立了事故树，由布尔代数方程求出了28个二阶最小割集，20个三阶最小割集，并计算出各基本事件的结构重要度系数。

Then the generalized moving least squares approximation is derived under adding the residual of high orders derivative.

从而，进一步导出了不仅要求近似函数还要求其任意阶导数在各节点处的误差的平方和最小的广义移动最小二乘近似。

However, the generalized moving least squares approximation makes require least squares approximation with regard to functional and its derivative value on all nodes.

而广义移动最小二乘近似要求近似函数及其导数在所有节点处的误差的平方和最小。

The moving least squares approximation makes only require least squares approximation with regard to functional value on all nodes. It makes no require for the residual of derivative approximation.

移动最小二乘近似只要求近似函数在各节点处的误差的平方和最小，对近似函数导数的误差没有任何约束。

For the sake of decrease of the computing time, modifying generalized moving least squares approximation is constructed under adding the residual of arbitrary high orders derivative only at the portion nodes.

为了降低计算工作量，构造了要求近似函数在全部节点处和任意阶导数在部分节点处误差的平方和最小的改进广义移动最小二乘近似。

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
