Study on the effect of underground hot water on fracturing and earthquake activities

Utilizing the geological exploring information of Houhaoyao area and digital seismic network's data of Huailai area, the author studied the role of underground fluids (hot water) in the fracturing activities and in the processes of seismogeny. The results show that the shear stress between two blocks of the fault is decreased rapidly and the vertical fault throw is obviously increased at the fracture segments where there is underground hot water action. With the vertical fault throw increasing, the shear stress transfers to two ends of the fault at the place where there is no underground hot water action, and the earthquake probably develops at these two ends of the fault.

组织演化理论在创业领域的研究应用探讨

本文介绍了Howard E.Aldrich教授在组织演化理论中的基本观点,并评述了该理论在创业领域的发展前景。组织演化理论是一种元理论。它的内涵丰富、范围多样,其基础内容包括四个通用过程:"变异(variation)、选择(selection)、保留(retention)、斗争(struggle)。"组织演化理论与创业理论联系紧密。本文认为,组织演化理论未来能结合中国情境,在创业者的身份认同、制度环境对创业行为的影响以及创业过程中的组织边界建构等方面做出一定的拓展。
