Limited bandwidth and high delay make application very difficult to archive good performance. In this dissertation, we have developed optimal collective communication library CAMPI for campus area based on MPI collective communication operation and have taken hierarchical network structure into account. In CAMPI, the number of clusters in system must be specified. We also must show which process belongs to which cluster.

本文充分考虑到网络的等级体系结构，针对不同的网络情况，在MPI集合通信的基础上提出了基于校园网系统的优化集合通信操作库CAMPI(campus area message passing interface)，它建立在MPI操作库之上，在CAMPI操作库中需要指定整个系统中有多少个机群，哪个进程属于哪个机群，CAMPI操作库在MPI之上实现，系统中必须首先安装MPI实现，例如最常用的MPICH。

We take them as examples for listing the microcanonical distribution,the canonical distribution and the grand canonical distribution for illustrating the idea.

本文根据刘维方程讨论了经典系统和量子系统处于平衡态时分布函数和统计算符应当具有的普遍函数形式，并以常用的微正则分布、正则分布和巨正则分布予以印证。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
