Potential sources are simplified as point sources or linear sources in current probabilistic seismic hazard analysis ( psha ) methods 摘要目前国内外常用的概率地震危险性分析方法中,一般把未来可能发生的地震震源(潜在震源)简化为点源或者是线源。
The vertical mixing law of the linear source in the natural river has been studied in the second step . at first the concentration equation of the linear source at different depth has derived . by the theoretical analysis , the relationship between the distance of the vertical homogeneous mixing and the part depth of homogeneous mixing , and the equation calculated distance of whole depth homogeneous mixing for the linear source have been presented 通过理论推导,得出任意位置上瞬时线源浓度场的解析解表达式;推导得到表面不同深度线源排放时垂向部分均匀混合水深随纵向距离变化规律的函数关系,并建立了相应变化规律的诺莫图;导出了表面不同深度线源在全水深均匀混合时的纵向距离的计算公式,应用长江口南通河段实测资料验证,得到一致结果。
