On the basis of intrapair and interpair correlation model, we have calculated the pair correlation energies of different kinds of systems, analyzed the changing rules of correlation energies of various electron pairs, and developed a reasonable and simple scheme called "Separating Large System into Smaller Ones". The basic idea of this scheme is that the correlation energy contributions of actual components in the ionic compound can be obtained using the correlation energy of ions with integer charge as the boundary conditions and incorporating the HF wave function or the distribution of electron cloud, then the total correlation energy of the system can be estimated by linearly summarizing the correlation contributions of these components.

在对内对间电子相关能理论模型的基础上，进行各类型化学键分子体系电子相关能的计算，分析电子对相关能的变化规律，建立合理的、&化整为零&的电子相关能简捷计算方案，其基本思想是对于离子键体系以整价离子的电子相关能为边界条件，通过HF波函数或电子云分布求得大体系中实际离子的电子相关能后，进行线性加和，即&化整为零、聚零为整&的思想。

Although most workers have found that samples containing ionizable components usually are best separated with mobile phases that have a pH less than or equal to 3 , some separations may be impossible at a low pH because components of the sample are unstable at a low pH; protonated basic compounds are eluted too soon; and required band spacings are unobtainable.

尽管许多工作者发现含有离子化组分的样品在流动相pH值低于或等于3的时候有最佳的分离，但许多样品不可能在低pH下分离，因为样品中组分在低PH下不稳定、质子化的生物碱洗脱太快、和不能达到要求的峰间距。

Under normal circumstances, this is not a problem because food proteins contain only the major components of nitrogen and other major components are not nitrogen, the Kjeldahl method is a very accurate determination of protein content .

在通常情况下，这不是个问题，因为食物中的主要成分只有蛋白质含有氮，其他主要成分都不含氮，因此凯氏定氮法是一种很准确的测定蛋白质含量的方法。

In this thesis, an improved method is proposed to overcome the problem that the circular color histogram method does not take the spatial information of colors into account , combines spatial distribution information with image color features. The presented method adopt color space which has the visual uniform , three components carries on no laddered quantification, three components weighting summation composes the row of the circular color histogram construction, and improves retrieval quality, while rotation and translation invariance of color histogram are kept.
