Firstly, this thesis makes an introduces on the developement of PMSM servo system based on DSP. According to the control theory of AC PMSM servo system, this paper analyzes the coordinate transformation, the rotor magnetic field orientation and the current control strategy of AC servo system. The control strategy is i_d=0. The system is orientates towards rotor magnetic field. Then the mathmatic models of PMSM in d-q coordinate are set up.

Bringing security metric as a QoS parameter is a new strategy in QoS routing.Aiming at the problems that the way of characterizing the link safety using only one security metric in QoS routing,a strategy that using multi-security metric as routing parameter is proposed.This will characterize the link safety much more exact.The authors will use the strategy mentioned before for secure routing based on differentiated service.

将安全度量作为一种QoS参数进行路由选择是目前网络安全路由研究的一个新思路，针对现有方法采用一个安全度量参数描述链路安全性，进行路由选择存在的问题，提出一种多安全度量的链路安全性描述策略，能够更加全面准确地描述网络链路的安全特征；该描述策略应用于区分服务模型下的安全路由选择，并提出了基于改进的非支配遗传算法的多目标最优化安全路由算法求解这一多目标多约束的NP完全问题。

Some of famous scholars focused on evaluation model known as "Black and Scholes option evaluation model" which was established by Fisher Black and Myron Sholes in 1973. Option evaluation is no doubt very important to trader but how to make capital gain through put-call strategy is more concerned.We examined if we can make profit by the evaluation model of option and spot to research Taiwan option market merely through strategy implementation.

有的学者著重于评价模式之建立，如Fisher Black与Myron Scholes於1973年，提出所谓的&Black and Scholes选择权订价模型&交易人对於选择权评价的方式虽然重视，但是他们更想知道的事如何运用选择权的买卖策略来获取资本利得，但在相关研究上，对於此领域的研究却不是很完善，所以本文将对选择权与现货标的的评价方式透过策略的运用，重新评价，以台湾选择权市场为研究物件，仅就策略性操作是否有其获利模式进行研究。
