This paper proposes a new Calking Dynamic Replication Distribution Algorithm(CDRDA) considering the communication cost among storage resource brokers and the characteristic of data accessing.

本文针对一的数据网格环境,考虑存储资源代理对数据的访问频和代理间的网络性能,提出一填空式数据副本分配法(CDRDA).

In complicated frequency components domain, wavelet scalogram and assigned wavelet scalogram were used to further analyze vibration signals.

频成分较复杂的地方，利用小波尺度图和再分配小波尺度图进行细分析。
