Introduce the cohesion-friction model of rock strength theory, and extend the model to select the strength of sliding plane, discuss the variation rules of peak strength and residual strength under different normal stress, and then present the selection model of shearing strength. After the result of cohesion-friction model is compared with Coulomb Criterion, it is found that when the results of shearing strength are many and adjacent the strength parameters can not be regressed by least square method, instead the results should be divided into some beelines at that time according to the cohesion-friction model.(4) Discuss the characters of hard structural plane and weak structural plane: The adhesive friction theory is applied to research the changing course of shear area of hard structural plane and its influence on shear stress.

3介绍了岩石强度理论中的粘接摩擦模型，运用此模型分析依附型滑动面的演化过程，并将其推广到边坡岩土体抗剪强度的选取，讨论了不同法向应力下峰值强度和残余强度随法向应力的变化规律，在此基础上给出抗剪强度的选取模式，讨论了对实际取值结果的影响，并与传统的Coulomb准则进行了比较分析，指出直剪试验的法向应力在小应力区的点较多且抗剪强度结果差异不大时，不宜直接运用最小二乘法回归抗剪强度参数，此时应结合粘接摩擦模型对结果进行线性分段。

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.
