中国地球物理学会首次地震成因讨论会1983年8月20—24日在兰州召开。来自全国38个单位的80多人参加了会议。会上共宣读了88篇论文。 会议就以下几个主要问题展开了热烈讨论: 1.地震的力学问题。许多同志认为,由孕震到发震是由缓变到突变的过程,其力源最终主要可能是热力,热可造成膨胀、升降与对流,可引起水平力与垂直力,垂直力又可转为水平力。地幔对流及其造成
China Geophysical Society for the first earthquake causes discussion August 20-24, 1983 held in Lanzhou. More than 80 people from 38 units nationwide attended the meeting. A total of 88 papers were read at the conference. The meeting held a lively discussion on the following major issues: 1. Mechanics of earthquakes. Many comrades consider that the process from geocentric shock to seismogenic shock is a process of gradual change from catastrophe to abrupt change. The ultimate source of force may eventually be heat, which may cause expansion, ascent and descent and convection, and may cause horizontal and vertical forces, and vertical force may be reversed For horizontal force. Mantle convection and its formation
