Result: At most up to 500 mg·L-1, tetrahydropalmatine showed no sinificant effect on the cell viability, while dehydrocorydaline, berberine and palmatine significantly decreased the cell viability, exceeding 6.3, 0.6 and 6.3 mg·L-1, respectively（ P .05 or P .01）. Tetrahydropalmatine, dehydrocorydaline, berberine and palmatine significantly inhibited LDH leakage induced by anoxia-reoxia injury, at concentrations of 50-100, 1.25-5, 4 and 30 mg·L-1, respectively（ P .05 or P .01）. None of the four compounds showed significant effect on the hydrogen peroxide injury.

Methods Ninety elective patients undergoing general anesthesia for hysterectomy were randomly assigned to two equal groups. GroupⅡreceived endotracheal intubation protected by sterilized transparent sleeve while groupⅠcorrespondingly adopted unprotective classical endotracheal intubation. Endotracheal swab sampling and bacterial counting were performed on the principle of aseptic processing before endotracheal intubation and extubation, respectively.

90例在全身麻醉下行择期全子宫切除术的患者随机分为两组，每组45例，Ⅰ组采用传统的气管插管操作方法，Ⅱ组采用无菌透明隔离套保护的气管插管操作方法，在气管插管前和拔管前分别按照无菌操作原则实施气管内试子取样，进行菌落计数。

Mankind steped three stages during the process of the conservation of geoheritages :(1) various countries set up their own national parks individually and unsystematically in order to protect their geoheritages;(2) various projects were iniated or promoted by international organizations to protect the geoheritages world wide;(3) the division of the Earth"s Science, Unesco sponsors "Geopark Program" and establishes "World Geopark Network, resulting in the entering a healthy development stage of geoheritage comservation.

中国地质科学院，北京100037 [2]中国地质科学院矿产资源研究所，北京100037摘要：人类对地质遗产的保护经历了三个阶段：①各国分散建立国家公园零星而无系统的保护地质遗迹；②国际组织发起和推动，形成全球保护地球遗迹的多项活动；③联合国教科文组织地学部提出地质公园计划和建立世界地质公园网络，使地球遗迹保护工作进入一个健康发展的新阶段。

The thesis mainly concerns the following aspects: the relay protection and its trip-close circuit of two circuits transmission-lines are stand alone. The device has the ability of phase-trip that is owns transmission line single phase , 2 or 3phases fault only fault phase tripped.so as to making the power system contact as close as possible. The function of reclosing distribute into relay protection of line and breaker, so it is easy to get no-serious fault information of line protection and realize self-adapted multi pole reclosing. The breaker reclosing depend on the state of owns breaker andthe adjacent breaker. The criterion of serious fault and the sequence reclosing is simple and useful.

本项目具有如下特点：两回线的保护装置及跳、合闸回路完全独立；装置具有分相跳闸功能，即本线单相、两相、三相故障时均只跳故障相，使得故障时系统联系尽可能紧密；重合闸功能合理分配在线路保护和断路器保护中，充分利用了线路保护的信息实现无严重故障判别和分相顺序重合策略的自适应重合功能，由断路器保护根据断路器本身的工作状态和相邻断路器的配合关系实现重合出口；判断严重故障的判据及分相顺序重合闸原理简单合理，具有实用意义，降低了重合于永久故障对系统的冲击。
