对西安市某污水管道进行水质测定和模拟，各组分实测值与模拟值的相对误差均小于5 . 0说明两者较为吻合，应用模拟程序可以对具有上述管道特征的排水管道内水质变化进行有效和较为准确的模拟。 - Our yields increase with the mass of the progenitor main - sequence stars . massive stars ( i . e . 18m < m < 50m ) is the primary sites of the neclearsynthesis of the r - process and can explain the galaxy chemical evolution . 3 . we present formula to calculat the r - process galactic chemical evolution of ba peak elements . this formula contains metallicity abundance and point out the relation of the ba peak elements and disscuss the effect of various mass supersnova . besides , our formula can be confirmed by a lot of observations
由此可以解释以下观测事实: ( l ) mg ， eu均产生于snh星，但质量范围不同，在高质量( > 20 ) eu的产量高， mg的产量(相对于太阳) ，导致晕星中eu / mg > 0 ，而产生mg的质量范围较大，致使在厚盘的晚期较小质量超新星也开始对mg有贡献，而这些星对eu的贡献很小，致使在厚盘星中eu / mg < 0 ，在厚盘中eu / fe随金属丰度的升高而降低，仁mg / fe随金属丰度的升高而不变
