On the basis of correctly describing the physical conception of sedimentary press,the paper first de-duced motion equation in bi-component composite uneven medium and further deduced displacement motion equation in exploration seismology and development seismology on that basis.
本文在正确阐述地层压力物理概念的基础上,首先推导出具有普遍意义的二组分复合不均匀介质运动方程,在此基础上推导出勘探地震与开发地震的位移运动方程。
The appearence characteristics of the heterogenous mixture zone near the bottom of weld metal in the fusion welded joint are studied through metallographic observations of many fusion welded joints.
通过时大量熔化焊接头的金相观察，研究了熔化焊接头焊缝底部附近“不均匀混合区”的形貌特征。
Experiment procedure on plate product technology of aluminum alloy 5083 from imperfection or non Homogeneous Treatment Process cast ingot is introduced.
介绍了5083铝合金欠均匀化或不均匀化生产板材工艺试验过程,比对了不同镁含量和不同均匀化程度对板材组织性能的影响,发现以上工艺变化对常规性能影响不大,对焊接等其他应用性能的影响有待进一步试验验证。
