定义域

On the other hand, since it is often impossible to solve the sub-problem exactly, the inexact algorithms were studied by many researchers. In our algorithm, the sub-problems were solved inexactly.

一般的邻近点算法只能求解算子在其定义域内的零点，而在实际问题中，往往要求解算子在给定区域内的零点。

The length of the windows and their width are adaptively adjusted by the planar histograms of the range blocks.

动态窗口的长和宽，根据定义域块均值和方差的二维直方图自适应地确定。

We will control the quality failure function curve according to the shift of the quality characteristics curve and the change of the curve's shape, the control method will be discussed.

依据模型的不同定义域，讨论了通过调整质量特性曲线的形状和位置来控制质量损失函数曲线的方法。

In chapter 2, we proposed a fractal image coding method based on genetic algorithms. The searching scheme problem of domain block in fractal image coding is well solved by applying a robust genetic algorithm with well-selected populations and revised genetic operators. Experimental result has show that it can increase fractal image coding speed by this method.

第二章在简介分形图象编码和遗传算法的基础上，提出了基于遗传算法的分形图象压缩编码方法；通过有目的选择初始群体、改造遗传算子等手段，较好地解决了分形图象编码中的定义域块搜索策略问题，大大提高了分形编码的速度。

Since RKPM is a kind of Galerkin meshfree methods, in this thesis, penaltyfunction method is employed to enforce the essential boundary conditions,trapezoidal rule is used for the approximation of displacement field function, Gaussand Hammer quadratures are applied for the numerical integration of systemequation,self-adapting method is applied for confirming the support of the pointinterpolated.

针对 RKPM 是一种伽辽金型的无网格方法，本论文采用罚函数法引入位移边界条件，用梯形积分法则近似位移场函数，对系统方程进行积分时分别使用了 Gauss 积分和 Hammer 积分，采用自适应的方法确定计算点的定义域。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
