近似程度

Finally, the complex surfaces are developed by partition of the surfaces into small surface segment ,and approximation of the small segment with the developable surface between two Bezier curves.

最后，采用分片与近似的思想，给出了复杂曲面展开的算法，并提出由曲面面积和曲面展开面积的相对误差调节分片程度来满足精度要求。

At the same time, the practical implementation of evolutionary algorithm is given in order that evolutionary algorithm is introduced into vector quantizer. In the fourth section the asymptotic theory of vector quantization is studied. Then the partial distortion theorem that when codebook size is large enough, each region of the partition makes an equal contribution to the distortion for an optimal quantizer, which is the key part of vector quantizer is obtained. Finally, the competitive learning algorithm based on the partial distortion theorem is proposed, which introduces the subdistortion of each region into the distortion measure to assure that the subdistortion of each region approximately equals to each other.

第四章详细研究矢量量化的渐近理论，然后得出了矢量量化器设计的核心部分——部分失真定理，当码本尺寸足够大且输出矢量的渐近概率密度与输入矢量的概率密度的幂成比例时，最优量化器划分的各个区域对该量化器的平均误差产生相同的影响，最后提出基于部分失真定理的竞争学习算法，它通过在误差测度中，引入与各区域相关的子误差以保证各区域的子误差近似相等，该算法实现较为简单，在一定程度上确保全局最优。

Since theparabolic system is an approximation from the elliptic system under small ray angle,we may have reasons to question the result of the parabolic system under large rayangle.

由于抛物方程是椭圆方程在小掠射角条件下的近似，我们有理由对抛物系统在大掠射角情况下的考察结果的可靠程度保持怀疑。

ABSTRACT It is very difficult to get exact mathematical models of industrial processes, models used in design procedure of control systems are commonly mathematical models through approximation.

在实际工程应用中通常很难得到被控对象的精确数学模型，在控制系统设计过程中所采用的模型常常是在一定程度上的经过近似化处理的数学模型。

The first reason is that the squared-magnitude frequency-response function is an analytic, real-valued function of a real variable, and this considerably simplifies the problem of finding a " best" solution.

有两个原因，往往是近似进程方面制定的平方大小的传递函数，而不是真正的和/或虚构的部分传递函数或复杂程度的传递函数。

To what extent can you see a similar "schizoid" character in this document?

在这份资料中你能理解近似於「精神分裂」的特质到怎样的程度？

Results show that, under the conditions depicted in this paper, generation rates of characteristic products don't speed up with increase of samples' initial aging degrees, but are consistent with the change of bond scission rate of cellulose. When samples are in mid-end life and aged further, the generation rate decreases almost exponentially.

结果表明：在该文的试验条件下，处于老化中后期的油纸绝缘，在后期继续老化过程中特征产物的生成速率随油纸绝缘初始老化程度的增加并不呈现递增趋势，而是成近似指数递减关系，这与纤维素绝缘纸降解过程中断键速率的变化一致。

I am really depressed, really, I look at the mothers to live frugally, in which approximate the degree of self-flagellation, I really distressing.

我真的很压抑，真的，看看母亲为我节衣缩食，哪中近似自虐的程度，我真的很心痛。

However, this almost sepulchral parlor, of which we have sought to convey an idea, is a purely local trait which is not reproduced with the same severity in other convents.

此外，我们刚才指出来的那间近似坟墓的会客室，那也只是种个别情况，在其他修院里不至于严厉到那种程度。

CHAPTER X ORIGIN OF THE PERPETUAL ADORATION Chinese However, this almost sepulchral parlor, of which we have sought to convey an idea, is a purely local trait which is not reproduced with the same severity in other convents.

十 永敬会的起源英文此外，我们刚才指出来的那间近似坟墓的会客室，那也只是种个别情况，在其他修院里不至于严厉到那种程度。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
