Since the numerical integration algorithm can estimate concentrations within the area source, the user can enter any value for the minimum distance.

对于面源范围内部的浓度，模式可以通过数值积分算法进行估算，所以用户可以输入任意小的距离。

Area source in engineering seismology is such a type of potential earthquake source which the positions and strikes of genetic faults are uncertain.

工程地震学中所指的“面源”属于这样一类潜在震源区——区内发震断层的位置和走向都是不确定的。

A new method of calculating long term mean concentration of air pollutant from area source is proposed by integrating the line source long term mean concentration model.

利用线源长期平均浓度模式对面源的积分得到了一个用风向、风速和稳定度的联合频率计算大气面源长期平均浓度的新算法。
