散布图显示，转换取代与颠换取代有类似的线性变化；支序分析及群聚分析的亲缘关系显示，同科及同属内的成员都群聚的很好，全爪蟎属与小爪蟎属的亲缘关系近，与叶蟎属较近的是岩蟎属。28S rDNA的序列特性显示，其核心序列适合分析较高阶的蟎蜱亲缘，而展延区则可应用於低阶的分析。

A class of affine nonlinear system of single input-single output is investigated. Firstly, the nonlinear system is transformed into an equivalent linear system through a diffeomorphism transformation. The networked control problems for the delays are constant, stochastic and shorter than a sampling period, and long and stochastic are investigated respectively.

And the solutions of the three problems above are discussed:The solution to the simulcast interfering which is caused by the simulcast delay spread and the zero-beating is given in chapter four.Based on the well understanding of the principle of MS-I/H/0 in IPNP, the examples are given in chapter five on how to solve the problem of communication interruption between paging zones.Through the analyse of signal switching between Chengdu and Deyang, the synchronization error between FLEX frames, and the bug in the multi-frequency roaming principle are pointed out. And solutions are also recommended.
