This paper proposes a new geographical-based clustering algorithm for MEO/LEO satellite networks management by introducing the concept of clustering of ad hoc networks.

通过引入ad hoc网络中分簇的概念，提出了一种适用于MEO/LEO卫星网络管理的基于地理信息辅助的分簇算法。

A better algorithm and corresponding real time implementation scheme are proposed. By methodic arranging the clocks of CPU and AD/DA, the scheme can not only scale the pitch in two octave range effectively, but also process the real time input audio for synchronous scaling output. The experimental results on Windows platform indicate the modest CPU and memory consumption, so as to meet the requirement of real time applications.

改造后的实时变调算法与实现方案通过合理控制CPU时钟和AD/DA时钟的时序关系，不仅能够在两个八度音范围内进行有效的变调，而且能够对实时输入的音频信号进行同步变调输出，在Windows平台上验证实验还表明新方案具有较低的CPU占用率和内存消耗，能够满足实时应用的要求。

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.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
