People are required to know and analyze the operating axes of rotary kiln in time in practice, in order to adjust and maintenance it in reason. So The Great Wall Aluminum Corporation of China bankrolled for studying the microcomputer real-time monitoring system of large-scale rotary kiln and commissioned Central South University to develop it.Based on analyzing and comparing the status quo of the monitoring system of rotary kiln, this paper brings forward a new method of monitoring the operating status of rotary kiln. It analyses the system-error and the configuration and demonstrate the feasibility in detail. In the design of hardware configuration it analyzes the principle and speciality of the tailor-made eddy current transducer and PCI-1713 analog input card and the multilevel supervisory network.

Introduced are the method and detail drawing of waterproof construction of basement anti-floating anchor rod and dewatering well.

对地下室抗浮锚杆及降水井处提出了防水作法及构造详图，抗浮锚杆处采用二道改性沥青油膏及二道改性沥青防水卷材防水，降水井处采用根据施工经验改进后的防水措施，增加了卷材套箍及滤水槽。

The evolution history of the volcanic rocks goes through five stages, the forming stage, the weathering and leaching stage, the burial and tectonic\|reforming stage, the erosion stage and the oil and gas accumulation stage. Finally, the model of porosity evolution was set up with andesite and basalt as examples.

在上述研究的基础上，将火山岩储集空间的演化过程分为火山岩的形成阶段、风化剥蚀淋滤阶段、埋藏和构造作用阶段、溶蚀改造作用阶段和油气聚集成藏阶段5个阶段，并以安山岩和玄武岩为例，建立了火山岩储层的孔隙演化模式。

The radial velocities at different radial positions under a constant flow rate, and at a definite radial position under different flow capacities were calculated and verified by the experimental data measured. The calculated results by using finite element method are in good conformity with the corresponding data measured by using laser Doppler anemometry.
