Based on the analysis of e-marketing, macro-strategies and micro-application of e-marketing are emphasized, A new concept is suggested, that is e-communication, e-research and e-trade which could be combined together to realize e-marketing. We suggest that we should make full use of all technique methods and communication patterns provided by e-business rather than limiting on simply e-advertisement or product promotion. According to the special features of e-marketing we can approach to choose the best e-trade pattern different with traditional way, such as trade information consignation obtain, electro-media, and virtual company etc.

基于对电子营销的分析，本文着重阐述了电子营销的战略及具体的实施方式，提出利用电子沟通、电子调研、电子贸易综合实现电子营销的概念，认为电子营销不应仅使用简单的电子广告，产品推荐等营销手段，而应充分利用电子商务所能提供的所有技术手段与交流方式，并根据电子商务的特点，选择不同于传统营销的营销方式。

This dissertation first puts forward the model of driving force transformation which the contact region of stator and rotor is divided into three relative sliding areas such as braking—driving—braking by means of research on vibration characteristics of USM stator surface points and micro driving course to rotor, this model can explain variation regularity of USM load characteristics, moreover, simplified calculation formula of rotor driving force concerned with stator teeth is set up.
