以所选模型参数代表点代入地震动随机函数模型，即可以得到地震动时程样本集合。

Substituting the represented points in the proposed random function model and performing the inverse Fourier transform yield the assembles of the stochastic accelerograms.

用于描述一定时间内交通流分布规律的离散随机函数包括泊松分布、二项分布、负二项分布等。

Two factors are considered including distribution functions and detected flow data, and a vehicle generator of micro-scale is proposed based on detection period.
