逼近的

Thirdly, for Bernstein-Durrmeyer-Bezier operators, we have given the approximation equivalent theorem in L_p(1 ≤ p≤∞).

三、我们给出了Bernstein-Durrmeyer-Bézier算子于L_p(1≤p≤∞)空间中逼近的等价定理。

It is a fitting and approximation of the source.

这是一套关于拟合与逼近的源码。

Some authors studied the rate of point-wise rate of convergence, asymptotic formula of Voronovskaja type, and some direct results about these type of operators.

Gupta等给出了有关这类算子点态逼近的速度、 Voronovskaja型渐近公式以及一些正结果。

In the forth chapter, a necessary and sufficient condition of the approximation by the partial sum of the generalized Baskakov operators is discussed.

第四章给出广义Baskakov算子用其部分和来代替进行逼近的一个充分必要条件。

There is nothing they can do to stem the collapse which imminently looms.

他们对紧迫逼近的崩溃，完全无能为力。

That could bring the luxury tax into view.

这就要考虑正在逼近的奢侈税了。

But as it grew closer the shape began to alter and mutate.

当它逼近的时候，一切突变

In chapter III,we consider the wavelet method for the approximation of the nu-merical Bergman kernel.It is very clear that the Bergman kernel plays an importantrole in the complex analysis and elliptic equations.The Bergman kernel has a closedrelation with the Riemann mapping,Green function,Neumann kernel and the Szeg〓kernel etc.

第三章研究了数值Bergman核数值逼近的小波方法，Bergman核在复分析和椭圆型方程中占有重要地位，它与Riemann映射、Green函数、Neumann函数、核等有着密切联系。

The saturation class and the saturation order of approximation are determined.

确定了逼近的饱和类与饱和阶。

This is the multi-resolution idea of successive approximation.

这就是逐步逼近的多尺度思想。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
