中文摘要：

在蛋白质的脊梁残余之间的取向被定义基于的在本地人配置和相应偏爱被统计分析。所有残余对有取向的一些特定的偏爱，这被发现。统计分析主要基于 hydrophobicity 和第二等的结构的特征为残余的二种组织在 orientational 分布被集中。为如此的二类型 ofgroupings 表演的统计不同 orientational 偏爱。它被发现那因为以前的组织 theorientational 偏爱是相当弱的，当时为以后一种强壮的 orientationalpreferences。这建议本地结构并且第二等的结构的形成是高度与 orientational 偏爱有关。

英文摘要：

The orientation between the backbone residues of proteins is defined based on the local configurations and the corresponding preferences are analyzed by statistics. It is found that all the residue pairs have some specific preferences of orientations. The statistical analysis is mainly concentrated in the orientational distributions for two kinds of groupings of residues based on the hydrophobicity and secondary structural features. The statistics for such two types of groupings shows different orientational preferences. It is found that for the former grouping the orientational preference is rather weak, while for the later a kind of strong orientational preferences. This suggests that the formation of local structures and of secondary structures are highly related to the orientational preferences.
