After a century, the kinetic theory of gases was also won the rapid development of .1857, the Clausius for the first time clearly statistical concepts, derived gas pressure, volume and temperature inter-correct relations, but also in 1858 introduced the concept of .1859 free path of molecular motion, the Maxwell velocity distribution law is derived, established the mathematical theory of transport processes .1868, the Boltzmann velocity distribution law was introduced in the gravitational field .

此后一个世纪，气体动理论才又获得飞跃发展。1857年，克劳修斯第一次清楚地说明统计概念，导出了气体压力、体积和温度间的正确关系，还于1858年引入分子运动自由程概念。1859年，麦克斯韦导出了速度分布律，建立了输运过程的数学理论。1868年，玻耳兹曼在速度分布律中引入重力场。

Finally, the wind velocity data of Nantong observatory are used to verify the methods above-mentioned, and the likelihood ratio method and Kolmogorov statistic are used to test the fitness of the distribution, It is obtained that the distribution of yearly extreme wind velocity of the observatory is in keeping with Frechet distribution, and the experimental distribution form from samples basically coincides with the theoretical ones.

本文将藉由有限差分法之数值模拟说明，在具有侧向变化之地层，其於空间上有非稳态之性质，并不符合一维反算之假设。

The conventional velocity analysis does not consider the influence of the NMO velocity varying with offset, making the results not ideal, leading to a poor stacking and migration imaging.

由于动校正速度是随偏移距变化而变化的。而常规速度分析并没有考虑这因素。

Speed is simply the amplitude of the velocity (the length of the velocity vector) without the direction.
