高斯扩散模式适用于均一的大气条件，以及地面开阔平坦的地区，点源的扩散模式。排放大量污染物的烟囱、放散管、通风口等，虽然其大小不一，但是只要不是讨论烟囱底部很近距离的污染问题，均可视其为点源。(The Gauss diffusion model is applied to homogeneous atmospheric conditions, as well as to ground open flat regions, and to point source diffusion patterns

最基本的解常微分方程的方法，包括欧拉法、泰勒级数法、多步法、隐式法、Rung-kutta法等(The basic methods for solving ordinary differential equations include Euler method, Taylor series method, multistep method, implicit method, Rung-kutta method, etc.)
