There are some creative points in the third part, they are as follows:1, This paper points out the primary strategies on the integration and optimization of the marketing channels: the administrators of mobile communication corporations should deepen the comprehension of channel model, design and manage the channels strategically; client orientation and product orientation are the key variation to the channel model; the inner channel management organization should be built, and improve the role and function of self-built channels in the channel system; societal agent channels should be integrated and cause agents to have a quality expand.; informationalized management should come into being gradually, which provide concrete technical support for finishing channel management.2, In order to built effective marketing channel system, this paper point out that mobile communication corporations should take measures as follows: building very effective self-operating channel system, optimizing business hall market channels; carrying out industry combination, building intimate business partnership relations; integrating industry chains, constructing new cooperative model of operators , end manufacturers and channel co-operators ; building benefit-shared machinism and effective channel checking and encouraging system; trying

本文的创新点主要集中在第三章，具体表现在： 1、提出了营销渠道整合与优化的主要策略：通信企业经营管理者要深化对渠道模式的认识，以战略理念指导渠道的设计和管理；客户导向和产品导向将是决定渠道模式的两大关键性变量；要落实企业内部渠道管理组织机构，提升自有渠道在渠道体系中的地位与作用；整合社会代理渠道，引导渠道成员实现质的扩张；逐步实现对渠道的信息化管理，为完成渠道管理任务提供坚实的技术条件支撑。 2、为建设有效的营销渠道体系，本文提出移动通信企业应采取以下措施：建立高效的自营渠道体系，标本兼治，完善营业厅窗口营销渠道；实施行业融合，建立紧密的业务伙伴关系；整合产业链，构筑运营商、终端厂商、渠道合作商新的合作模式；建立利益共享机制；建立有效的渠道考核及激励机制，努力控制核心社会渠道。

A mixed sensitivity H∞ control model is constructed and the band width of wind turbine speed control is designed according to the frequency characteristic of wind speed variation and noise of rotating speed sensor. The sensitivity function is decreased within this frequency band to restrain the wind torque perturbation to wind turbine rotating speed control.

通过构造基于复合灵敏度的H∞鲁棒控制模型，根据风速的波动频率范围和传感器的噪声频率范围设计了风车转速控制的带宽，并在此带宽内降低系统的灵敏度函数，来抑制风力转矩对风车转速控制的干扰。
