江厦湾网箱养殖鱼体内重金属的积累、分布与环境效应

对江厦湾网箱养殖鱼类-黑鲷、鲈鱼、红鲈体内组织中重金属Cd、Cr、Zn、Cu、Pb的含量进行分析,同时测定该鱼类生长环境中海水的重金属含量,结果表明:在不同鱼体的不同组织中,各种重金属含量差异显著,肌肉中重金属含量较少,而鳃和鳍中含量较高;通过比较发现,鱼样体内组织中重金属的含量,与该鱼类生长环境中海水的重金属含量存在正相关的关系;该区域海水中重金属Zn、Cu、Pb的含量明显高于其它区域.     

冲击破煤过程中能量耗散的理论分析

介绍了能量在冲击式破煤过程中的产生、传递和耗散过程以及能量最终的分布范围;运用应力波的方法分析了应力波在煤体中传播过程,并得出能量在衰减过程中衰减率的计算方法;还分析了剥落厚度的计算方法,并得出正弦应力波在煤体中传播时的冲劈厚度和最大煤块尺寸的关系;根据冲击规律和能量的传递特征对能量的传递过程进行了分析,并求出冲击消耗能量和最小散逸能之间的关系,指出了要使煤块破碎必须满足冲击消耗能量要大于最小散逸能。     

“变通权”与国家法制统一

历史和基本国情决定了我国解决民族问题只能走民族区域自治的道路，这是解决民族问题的中国模式。民族自治与区域自治相结合的民族区域自治法律制度赋予少数民族地方“变通补充权”，体现了国家充分重视和保障少数民族管理本民族内部事务的权利。它与实行各民族平等、团结、共同繁荣的原则和国家法制统一原则是一致的。

Disaster Reduction Decision Support System Against Debris Flows and Landslides Along Highway in Mountainous Area

Highways in mountainous areas are easy to be damaged by such natural disasters as debris flows and landslides and disaster reduction decision support system (DRDSS) is one of the important means to mitigate these disasters. Guided by the theories and technologies of debris flow and landslide reduction and supported by geographical information system (GIS), remote sensing and database techniques, a DRDSS against debris flow and landslide along highways in mountainous areas has been established on the basis of such principles as pertinence, systematicness, effectiveness, easy to use, open and expandability. The system consists of database, disaster analysis models and decisions on reduction of debris flows and landslides, mainly functioning to zone disaster dangerous degree, analyze debris flow activity,simulate debris flow deposition and diffusion, analyze landslide stability, select optimal highway renovation scheme and plan disaster prevention and control ergineering. This system has been applied successfully to the debris flow and landslide treatment works along Palongzangbu Section of Sichuan-Tibet Highway.

China'''' s Fundamental Research in Energy Utilizations and Environment

The progress in the science of energy utilizations will act crucial effect on the developments of energy science and technology, which will then promote social and economical developments and fulfill requirements for the national strategic objectives. For the sake of sustainable development, a harmonious blend of energy utilizations and environment considerations will become one of the vital topics in the future research area of energy science. It is suggested that clean and high-efficiency utilization of traditional or fossil energy resources, fundamental investigations on the energy and environment theory, renewable energy utilizations, and the development of nuclear energy are selected as priority research areas during the period of the Tenth Five-year Plan of China, according to the development trend of the world energy science and the research background of Chinese energy science. It is expected to promote the interdisciplinary investigations in the science of energy u-tilizations and provide scien
