Therein, by adopting the ISCSI protocol, the local data storage sub-system constructs the circuital access pattern of the taxation data. The system eliminates the unbalance phenomena between the capability and the demand of the data storage under the traditional bus storage pattern. Under the centralized control pattern, it provides the information access and shares service with the great data volume, the high speed of data transportation and the high availability for the taxation system. By remotely building a backup data center that is totally consistent with the local data center on the IT foundational fabric, the remote data backup sub-system uses the geographical dispersibility of the remote data center and adopts the LVR software replication technology. It implements the synchronous data replication between the local and remote data center, changes the zero standing capability on the great disaster event under the single data center pattern and raises the standing capability on the disaster events for the application and data in the taxation system. By adopting the dynamic replication technology between the heterogeneous data source, the heterogeneous data conformity sub-system successfully shields the various heterogeneous ingredients of the present system.

其中，本地数据存储子系统采用ISCSI协议构建了税务数据网络存储模式，消除了传统总线型存储模式下数据存储性能和存储需求之间的失衡现象，在集控管理模式下为税务系统提供了超大数据容量、高数据传输率和高可用性的信息存取和共享服务；远程数据备份子系统通过在异地构建一个和本地数据中心IT基础架构完全一致的备份数据中心，利用远程数据中心在地理上的分散性，基于LVR软件复制技术实现了本地和远程数据中心之间信息的实时同步，改变了过去单一数据中心模式下对大型灾难事件的零抗灾能力，提高了税务系统内应用和数据对灾难性事件的抵御能力；异构数据整合子系统采用异类数据源动态复制技术，成功屏蔽了目前系统内存在的各项异构成分。

And the perfect Q-vector was applied to diagnose a heary rain process for August 3～5, 1996. The results showed that there were more advantageous using the perfect Q-vector, and suggested that the perfect Q-vector could clearly reveal the system development of the heary rain; the divergence center or line, the divergence field and the frontogenesis function field of the perfect Q-vector could be used to locate the heary rain area; the center magnitudes of the perfect Q-vector divergence field and the frontogenesis function field could be signified the intensity of the heary rain.

结果表明，完全Q矢量能较清楚地揭示暴雨天气系统的演变；考虑了湿过程的完全Q矢量在暴雨的诊断过程中显示了其更大的优越性；定性而言，完全Q矢量散度的辐合中心或辐合线、散度场和锋生函数场有助于确定暴雨的落区，暴雨区正好落在低层完全Q矢量散度场辐合中心和锋生函数场正值中心之间；定量而言，低层完全Q矢量散度场辐合中心和锋生函数场正值中心大小对暴雨强度有显著的指示作用。

Viewing from the angle of the science of law and taking "rights" as the text for analysis,this article discusses the theoretical divergence on "the rights of nature" between the anthropocentrists and non-anthropocentrism.The anthropocentrists criticize the rights of nature from four aspects,its humanity,impracticality, uncontrollability and non-equivalence of its duties.The n...

从法学视角切入，以&权利&作为分析文本，论述了人类中心主义与非人类中心主义在&自然权利&上的理论分歧，人类中心主义者从权利的属人性、权利义务的不对等性、主张自然权利的非现实性以及自然权利的不可操作性四个方面对自然的权利提出了批判，而非人类中心主义者指出权利概念的在不断地扩展，人类中心主义不可能完全解决好人与自然的关系，自然权利存在着转化为在法律上具有可操作性的可能，并且自然权利理论已在法律实践领域拓展，对自然的权利进行了辩护，由此提出了&非人类中心主义&、&自然的权利&的环境伦理定位。
