PLIC3D algorithm, a 3-dimensional VOF method with piecewise linear interface construction and split and unsplit propagation, is specially devised for better solution to free surfaces. Particularly split PLIC3D is applied in numerically modeling draining from bottom of a cylindrical vessel and water-exit of a revolution body, from which evolutions of free surfaces are mainly illustrated.

重点在直角坐标系中推导了用斜面构造自由界面，使用分裂和不分裂推进的三维VOF方法：PLIC3D，以改善自由面求解精度；并用分裂的PLIC3D算法模拟了三维的柱形容器泄漏和旋成体出水问题，结果主要显示了它们的液面运动变化。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
