余维数

In chapter 4, we study homological dimensions of H-invariant subring for Hopf astions and smash coproducts.

在第四章，我们研究了Hopf作用的不变子环与smash余积的同调维数。

A heuristic search strategy and a practical example are given.The result shows the consistent feature selection reduction method can eliminate the disaccords of the sample dataset,select the optimal feature variables,drop the dimension of the data and reduce the redundancy information effectively.

给出的启发式搜索策略和应用实例表明：一致化特征选择约简方法能有效消除分类数据集的不一致性，选择最优的特征变量、降低数据的维数、减少数据集中的冗余信息。

Ltd. have designed hundreds of vacuum furnace, test platform, vacuum equipments and other vacuum supported products for enterprises, companies,universities and so on .

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。
