The difference of bulk density of coastal soils took an effect on infiltration rate and diffuse rate. The infiltration rate and diffuse rate of coastal soils which bulk density was small were big. The water transmitting experiment of coastal soils showed that the saturated conductivity of different layers in soil profile were great, and the saturated conductivity of undisturbed soil was highly higher than that of disturbed soil. The saturated conductivity of coastal soils embanked earlier was lower than that of coastal soils embanked later. Under different water content, the unsaturated conductivity of coastal soils had a great change and the bulk density had an effect on unsaturated conductivity. The soil with a low bulk density had a high unsaturated conductivity. Chlorine ion moved in coastal soil was an inert ion. The distribution of CU in soil was definite and repeated, which is no relation with the time and velocity of infiltration. The concentration of infiltration solution and the texture of coastal soils had no apparent effect on solute movement synthetic dispersion coefficient, while bulk density took an apparent effect on solute movement synthetic dispersion coefficient. Synthetic dispersion coefficient of coastal soils increased as bulk density decreased.

Based on the simulation data, the effects of clearances, damping coefficient and the rotation speed on the dynamic behaviors are studied: compared with ideal mechanisms, mechanisms with clearances are less stable; as for mechanisms with clearances, when the crank rotates at the speed of 100rad/s, the actual clearances are always above the radium of clearances, axle pin and axle cover keep contact throught the rotation; when the crank rotates at the speed of 20rad/s, mechanisms are in an unstable state, at an angle of about 300, the actual clearances are below the radium of clearances, pairs lose contact, which results in collision between them; with the speed of 20rad/s, when damping coefficient is assumed 175Ns/m, distinct separation and collision happen between pairs; when damping coefficient is assumed 220Ns/m, separation and collision are controlled.

在含间隙机构中，当曲柄以100rad/s转动时，运动副间隙始终大於半径间隙，轴销与轴套始终保持连续接触；当曲柄以低速20rad/s转动时，系统处於极不稳定的震荡状态，在转至300°左右时，运动副间隙小於半径间隙，脱离接触，发生明显的分离碰撞现象。在含间隙机构中，曲柄以低速20rad/s转动，当取法向阻尼系数为175Ns/m时，副元素发生明显的分离碰撞现象；当取法向阻尼系数为220Ns/m时控制了副元素的分离，副元素一直处於连续接触状态。
