RemoveAt;' removes the specified index ' A Queue does not have the concept of an arbitrary remove ' Use Dequeue to read, AND remove the top element off the Queue q.

RemoveAt 要求您提供要移除元素的索引，而这对"队列"或"哈希表"没有意义（这就是"队列"和"哈希表"不支持 RemoveAt 方法的原因）。"队列"是特殊情况，因为移除"队列"中的元素只可在"队列"的顶部元素上执行。

由于环R满足相对可比性当且仅当R的每个正则元是相对幺正则的，§2.2节给出了一般环中给定的正则元是相对幺正则的一些特征刻画，证明了文献[22]（1997）的主要结果在任意环中仍然成立。

In the paper, an optimal method for node labels in the finite element is presented, which is an inductive and deductive method. By the analysis to the order features of the nodes when the network bandwidth is the minimum value, we can induce three regulars. Testing a large number of examples, which show that the presented scheme can reduce bandwidth for arbitrary mesh by renumbering the nodes, proves the correctness and reliability of the regulars. Thus the memory of computer is saved and the compute efficiency is improved.
