In this paper, preparation and optically stimulated luminescence of the electron trapping optical storage material were studied. Rare earth elements doped CaS, SrS and CaSrS were prepared by carbon-powder atmosphere reducing method ( CARM) and carbon-powder direct reducing method ( CDRM) respectively.

分别采用碳粉气氛还原法和碳粉直接还原法制备了稀土掺杂的三种不同基质的电子俘获材料（CaS、SrS、CaSrS）。

The foundation of the CDRP is the a-Stable Path-based Clustering Algorithm ( a-SPCA). The purpose of the a-SPCA algorithm is to predict network partitioning by clustering.

基于α-稳定路径的分簇算法α-SPCA是CDRP协议的基础，其目的是通过分簇预测网络分割。

The CDRP mainly aims to improve the data availability, and then to reduce communication cost of data access to improve data access performance, and to reduce the network load to improve the scalability of the protocol.

其主要目标是提高数据可用性，并在此前提下减少数据访问的通信开销和协议带来的网络负载，以提高数据访问的性能并增强协议的可扩展性。

The CDRP includes clustering algorithm, metadata management protocol, replica management protocol and probabilistic reliable dissemination protocol.

CDRP协议主要包括分簇算法、元数据管理、副本管理和概率可靠的分发协议四部分。

Because of the asymmetry characteristic of BWIP networks, the existing security architecture frames can not completely satisfy the security requirement of the future BWIP networks, such as ISO/ IEC7498-2, IPsec, WAP, 3GPP and CDSA.
