岩矿石吸收系数的算和测定方法

岩矿石吸收系数是钻孔电磁波法解决地质问题的重要的物性参数。岩矿石有无吸收系数的差异，是开展钻孔电磁波法能否奏效的前提．了解岩矿石的吸收系数可对钻孔电磁波法的透距和分辨力作出估计，并可为钻孔电磁波的反演解释提供重要的依据．本文不但给出了岩矿石吸收系数的计算方法，也给出了室内岩矿石标本吸收系数的测定方法和野外实测岩矿石吸收系数的方法。     

碳酸盐岩地区电磁波场的特性分析

形成岩溶的高阻碳酸盐岩对电磁波的吸收较弱，而且成层沉积的特定环境使碳酸盐岩地区岩石的各向异性现象较明显，由于地空界面的存在及岩溶洞壁两侧介质电性差异明显，界面清晰，又使电磁波出现强烈的反射及散射现象，从理论上对碳酸盐岩地区电磁波传播的特有现象进行了研究和分析，并给出结论。     

注水试验资料分析

注水试验方法是 Ferris 和 Knowles 先生在1954年首先提出的,这包括向一个有限口径的井中注入或抽出已知体积的水,来查明有限含水体的贮水系数和导水系数.Cooper 等人根据有限含水体的不稳定辐射水流方程采用一套模型曲线推求含水体参数值.     

Ocean storage of nuclear wastes? Experiences from the Russian Arctic

An international demonstration (RD&D) project for ocean storage of radioactive wastes should be proposed, to study the feasibility of the concept of ocean storage of nuclear waste. This international project should utilize the scientific, engineering and technical capabilities of selected universities, oceanographic institutions, NGOs and industries. This project would need to be an independent (non-governmental) study, utilizing the capabilities of selected universities, oceanographic institutions, environmental NGOs (Non-Governmental Organizations) and industries. Scientists and engineers first need to conduct an engineering, environmental, and economic feasibility study of the concept. The goal of the project would be to determine if ocean-based storage reduced the risks to the environment and public health to a greater degree than land-based storage. This would require comparing the risks and factors involved and making the data and information available to anyone, anywhere, anytime on the internet. The mere presence of an investigation of the ocean storage option could facilitate scientific and engineering competition between the two options, could subsequently reduce environmental and public risks and provide better protection and cost benefits in the system utilized. One of the primary concerns of the scientific community would be related to the sensitivity and precision of the monitoring of individaul containers on the ocean bottom. An advantage of the land-based option is that if there is a release, its presence could be detected at very low levels and be contained in the storage facility. On the ocean bottom, a release from a container might not be easily detected due to dispersion. Therefore the containment system would have to be a system within a system with monitoring between the two providing greater protection. Ocean storage may have greater technical and political hurdles than land-based options, but it may provide greater protection over time, because it negates the threat of terrorism, it therefore merit further study. In the future if the use of nuclear energy and nuclear wastes increases, the global society could benefit from this international project, because it could reduce environmental and public health risks and promote energy independence.
