This paper, firstly, after a deep study of image mathematical models, sets up two kinds of image models namely Laplace partial differential equation model and biharmonic equation model and then obtains the eigenvectors of image by the methods of eigenfunction expansion and boundary recurrence.

本文首先较深入地研究了图象的数学描述，提出图象的Laplace偏微分方程和双调和方程两种模型，继而采用特征函数展开法和边界递推法分别求得图象的特征矢量。

The elephant is not immediately susceptible to such blandishments, however, and usually lashes fiercely with its trunk in all directions.

两位助手骑在驯服的象的背上，从两侧控制新捕的象，其他人唱着单调的歌声用手抚摸象的皮肤。

The first is on the study of spectra technique in boolean function and in its probability function.

得到布尔差分等布尔运算在此映射下的实函数运算，并用有限离散变换实现了从原函数到象函数、到象函数偏差分，以及到布尔差分的象函数的变换，并研究了这一系列变换的性质。

The dissertation aims at automatic target recognition in images. For that purpose, a variety of algorithms proposed by the dissertation have been used in different stages of image recognition, which deal with image segmentation, boundary feature point extraction, curve feature extraction, object invariant representation and recognition.

本论文的研究目标是实现图象中目标的自动识别，为此，论文围绕图象识别的各阶段，研究了图象分割、轮廓特征点提取、曲线特征提取、物体的不变性表征及识别等。

People said that he resembled Byron,- at least that his head was Byronic; but he was a bearded, tranquil Byron, who might live on a thousand years without growing old.

有人说他象拜伦--就是头象，至于脚可不象：他的脚并没有毛病，不过他的两颊和嘴上比拜伦多一点胡子，性情也比拜伦温和，就是活一千岁他大概也不会变样。

He stayed there for several hours till the mother got used to him; he had to be introduced, was allowed to touch her long trunk and to feed her some fruit and sugar cane.

他待在那有几个小时，至到母象习惯了他的存在。他必须经人介绍，准予去触碰母象那长长的鼻子，并给象喂了些水果和甘蔗。

I am about to be seized with a fit of catalepsy; when it comes to its height I shall probably lie still and motionless as though dead, uttering neither sigh nor groan.

我得的是癫痫病，当它发作很厉害的时候，我或许会一动不动地躺着，象死了一样，并发出一种既不象叹息又不象呻吟那样的喊声。

The results indicate that there are 8 stable conformers for D4G in gas phase. The conformer d4g-2 is the most stable form of all conformations in gas phase.

结果表明，孤立的D4G分子在气相中存在8种稳定构象，其中构象d4g-2是所有构象中最稳定的，气相中D4G主要以d4g-2存在。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
