Because the XSLT processing model is "write-once, read-many," the synchronization logic can be much simpler, leading to faster navigation of the tree.
由于XSLT处理模型是“写一次读多次”的，同步逻辑可以变得更简单，使浏览树变得更快。

Secondly, the synchronization based on ringed topology is designed, which is totually different from the present meathod based on the tree, star or P2P model.
其次，基于现有的树型，星型或是P2P网状同步拓扑系统的研究基础，提出环状同步拓扑下的同步系统设计。

A binary tree routing topology is designed for propagating the system clock and trigger signal and the accurate timing and synchronization between sensors are provided by CPLD.
