合作原则对高职英语教学中师生会话的启示

Grice提出的会话合作原则是保证会话顺利进行的有效标准和手段.在一般的正常交流中,人们都能自觉或不自觉地遵守会话合作原则,从而实现有效的人际沟通.但是在高职英语教学中,由于师生之间的信息不对称等因素导致师生会话往往难以展开,难以实施交互式教学.本文从合作原则出发,分析了制约高职英语教学中师生有效会话的因素并提出了相应的教学对策.

从商家的促销活动看接受策略

每一个节假日来临,对商家而言意味着一个商机的到来。要想在激烈的促销的活动中脱颖而出,商家必须做到知己知彼,迎合消费者的心理,出奇招而制胜。文章尝试从接受修辞学的角度分析促销活动所蕴含的修辞接受策略。     

活动标形及其在点啮合齿轮传动误差分析中的应用

活动标形法的论述首推苏步青译，佐佐木重夫著《微分几何学》，还有的著作从外微分形式引入活动标形,本文论证取曲面的正交曲率网为参数网时，曲面论的基本公式就是活动标形的微分形式，并用其分析了点啮合齿轮传动误差．     

Small Stress Change Triggering a Big Earthquake： a Test of the Critical Point Hypothesis for Earthquakes

Whether or not a small stress change can trigger a big earthquake is one of the most important problems related to the critical point hypothesis for earthquakes. We investigate global earthquakes with different focM mechanisms which have different levels of ambient shear stress. This ambient stress level is the stress level required by the earthquakes for their occurrence. Earthquake pairs are studied to see whether the occurrence of the preceding event encourages the occurrence of the succeeding one in terms of the Coulomb stress triggering. It is observed that the stress triggering effect produced by the change of Coulomb failure stress in the same order of magnitudes,about 10-2 MPa, is distinctly different for different focal mechanisms, and thus for different ambient stress levels.For non-strike-slip earthquakes with a relatively low ambient stress level, the triggering effect is more evident,while for strike-slip earthquakes with a relatively high ambient stress level, there is no evident triggering effect.This water level test provides an observational support to the critical point hypothesis for earthquakes.
