Upon this, we forward more deeply: the emergence of the null phenomenon and the removal method of it; the operator selection in Genetic algorithm; improvement of object function and the introduction of the punishment method, etc.

在此基础上，本文进行了深入的专题研究：零空间现象形成的原因及消除方法；遗传算法中选择操作的研究；目标函数的改善，惩罚机制的介入等，并取得了一系列的成果。

It can avoid overdoing the generalization.(3) Imputation of unknown values. To the incomplete information systems,the dissertation suggests a new method to impute the null values. The method is based on the extending model of rough sets and fully considers the consistence of data and dependency of attributes.

为了提高GDSS决策能力，本文提出了将粗糙集理论与层次分析法相结合的思想，利用粗糙集理论所确定的属性间的依赖关系，分析应用系统运行所积累的大量数据中各决策因素、决策者对决策目标的影响，构造具有完全一致性的个体判断矩阵和综合判断矩阵，建立自学习系统，克服决策者主观因素对决策结果的影响。

The data a GetChunk call returns is assigned to variable. If Size is greater than the remaining data, the GetChunk method returns only the remaining data without padding variable with empty spaces. If the field is empty, the GetChunk method returns Null.

此方法取回的数据赋值给一个变量，若Size参数大于还需要取出的数据，则该方法返回剩余数据且并不在该变量后添加空格，若字段为空，则该方法返回NULL值。

The detail contents can be summarized as follows: Using Grassmann line geometry method to analyze joint axes linear dependence in manipulator singular configurations; The manipulator constrain equations are derived base on the reciprocity of twists and wrenches; The null space method is used to obtain the reciprocal screws when singularity occurs.
