单自由度任意时程荷载响应分析
说明： 已知单自由度受迫振动体系的运动方程的解，是由齐次方程的通解与特解组成。其次方程的通解在无阻尼、临界阻尼、低阻尼、超阻尼中各有不同。(It is known that the solution of the motion equation of a single degree of freedom forced vibration system is composed of the general solution and the special solution of the homogeneous equation. Secondly, the general solution of the equation is different in undamped, critical damping, low damping and super damping.)

气体高斯扩散模型模拟_代码
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. Chimneys, pipes, vents, etc. that emit large quantities of pollutants, although they vary in size, can be regarded as point sources as long as they do not discuss the pollution problems near the bottom of the chimney.)
