震源机制解 meaning in Chinese

focal mechanism solution

We analyzed and studied the structure environment , the epicenter mechanisms of medium - strong earthquakes , time and space distribution of medium - strong earthquakes and the relation between the small earthquakes clusters around baicheng and medium - strong earthquakes in the seismic field of south tianshan mountain
摘要分析研究了南天山地震带构造环境、中强地震活动震源机制解、中强地震时空分布以及拜城周围小震群活动与中强地震的关系。
Based on the fromer study of mine tectonic , hydrology , tunnel deformation , etc . , 3 - d numerical simulation of current tectonic stress field of lvjiatuo coal mine was done in this thesis , combining with local hypocenter mechanism solve and relational stress in - situ measuring value regression analysis has been done to the simulation result , and the reasonable results are gained those will offer dependence for disposing the tunnels more rational and making tunnel supporting more economical and safer
摘要本文在前人对吕家坨矿进行矿井构造、水文地质、巷道变形等研究的基础上，结合该地区的震源机制解及有关的应力实测值，对矿区现今构造应力场进行了三维数值模拟，并对模拟结果进行了线性回归分析，得到了与现实较为符合的结论，为更合理的巷道布置和更经济而安全的巷道支护提供依据。
