By testing many examples, we analysis the dependency of the algorithm ICS for the various orderings and involutive divisions.

通过大量的计算试验，我们分析了此算法对不同等对合除法以及项序的依赖关系，获得了一些试验性的结论，这些结论对今后代数偏微分方程组的对合特征集的计算具有一定的指导和借鉴意义。

基础科学，数学，代数、数论、组合理论双色图；非负矩阵对；指数；指数集

Finally,through some ideas from Algebraic Geometry,we constructed strongly exceptional collections of derived sheaf categories,and solved the problem that equivalences between some posets.

最后，通过代数几何里的一些思想，我们构造了导出层范畴的强例外集合，解决了一类偏序集的等价问题。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
