Water is filled into 1/3-2/3 of underground solution cave, and light type nuclear fusion body is put into the cave. Igniting the nuclear fusion body make water reach water vapour state in high temperature and high pressure 300-400 deg.C and 30-40Mpa, which drives rotation of turbo generator to generate electricity. With power being done, exhaust steam is condensed in condensator. Then, igniting the nuclear fusion body is carried out in another solution cave.

Considering the dispersity, covertness and fuzziness of drawing information, we propose a layered interpretation technology for engineering drawing based on geometry complexity. This technology uses layered organization of drawing information and primitive layered recognition based on the integration of drawing information to get the entity.

本文针对图样信息分散性、隐含性、模糊性的特点，引入了图样信息几何复杂度的概念，在此基础上提出了工程图样的层次理解技术，即通过对图样信息的分层组织和基于图样信息集成的基元体分层识别得到图样所表达的形体。

Seven types of dimetric drawing and three types of trimetric drawing are introducedby the author with an aim to help hasten the shift of the principles derived from varioustypes of dimetric and trimetric projections from the theoretical approach to the field ofpractical use,and to alleviate the embarrassing situation that only the simple methodscan be resorted to in drawing the pictorial projections by isometric drawing and cabinetdrawing.

为了使各种形式的正二测和正三测从理论研究转向实际应用，克服长期来人们在绘制轴测图时，多数只能采用正等测和斜二测等单调情况，以及提高绘图速度，本文推荐采用七种正二测和三种正三测，并设计一套绘制这十种正轴测的专用工具--轴测多角比例尺。本文提出一套近似作这十种正轴测坐标面上椭圆的方法和数据，使其既简便又准确。

Through similar simulation test of block top-coal drawing, the influence of coal block size and block position in top coal on the recovery ratio and drawing manner is studied. It is found that the drawing manner has the different adaptation to the top coal which has different block distribution. The caving capacity is mainly decided by the block size. The top-coal which has layer difference of block with the same size has different recovery ratio. It is shown, that, to the given top-coal blocks, the recovery ratio of uniformly mixed blocks is maximal in the manner of drawing at interval of one support.

研究表明，顶煤块体大小是影响顶煤回收效果的主要因素，在顶煤块径一定的条件下，块体层位分布不同是造成顶煤回收率差异的主要原因，研究表明各级块度均匀混合时顶煤回收效果最好，块度从下向上增大分布次之，大块为中位顶煤时回收效果最差；各种放煤方式的适应性不同，各级块度均匀混合的顶煤适合用间隔放煤；块度从下向上增大适合用顺序放煤；大块在顶煤中位分布时，中硬煤以下适合用间隔放煤，硬煤应采用顺序放煤方式。
