Adopting the AFOSM method of reliability analysis, assuming the unit weight, co hesion and internal friction are mutually independent stochastic variables, thei r influence on the reliability of the tension resistance of the anchor rod has b een analyzed.

采用可靠度分析的改进一次二阶矩法，假定粘性土的重度、粘聚力、内摩擦角为互相独立的随机变量，分析了它们对于锚杆抗拉力可靠性的影响。

Using the dynamic simulation software ADAMS to analyze the six-bar mechanism of shaping machine ;and through the virtual prototype,we get the optimum point from the optimization design of the acceleration and the press angle of shaping machine for the real machine;and we can get an example to the study of virtual prototyping.

简要介绍多体系统动力学的原理及多体系统动力学计算的积分方法，利用动力学仿真软件ADAMS，对牛头刨床的六杆机构进行分析，并通过虚拟样机技术，对牛头刨床加速度和压力角进行了优化设计。为实际的机构设计提供依据，也为虚拟样机技术的学习提供了实例

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。
