Single factor experiments were done with the factors including the width of protrusion and the trolley's velocity, which showed that the surface frictional coefficient decreases with the width of protrusion increasing, and doesn't change with the trolley's velocity changing, which was consistent with the results of the orthogonal experiment. A theoretical model of the horizontal projection of a corrugated bionic surface's contact area was built, which showed that the contact area's horizontal projection decreases with width and interval increasing respectively and that the ratio of the contact area's horizontal projection and the vertical load decreases with the vertical load increasing. It indicated that the surface frictional coefficient decreases with the above three factors increasing respectively. Finite element modeling and analysis of interactions of a plate and soils was done using ANSYS, which showed that the plate frictional coefficient is little relative to soil elastic modulus and decreases with vertical surface pressure and that trolley's pull and vertical displacement of bionic surface's control pilot keep constant almost during the plate being pulled. Finite element modeling and analysis of interactions of a corrugated bionic surface and soils was done using ANSYS, which showed that surface frictional coefficient is little relative to soil elastic modulus and decreases with bionic surface's structural parameters and vertical pressure increasing. However, the three factors all didn't affect the surface frictional coefficient remarkably on the condition of 90% dependability. For the first time, bionic surfaces were applied to screw piles, which formed bionic screw piles, and the contrast experiments showed the bionic screw pile had certain resistance-decreasing effects.

建立了波纹型仿生曲面与土壤的接触面积的水平投影的理论模型，表明接触面积的水平投影A随着波纹型仿生曲面突起宽度、两相邻突起间距的增大而减小，接触面积的水平投影与波纹型仿生曲面表面垂直载荷之比随着波纹型仿生曲面表面垂直载荷的增大而减小，进而得出仿生曲面摩擦系数随着波纹型仿生曲面突起宽度、两相邻突起间距以及表面垂直载荷的增大而减小；利用ANSYS软件对平板与土壤的相互作用进行了有限元建模与分析，表明平板摩擦系数与土壤弹性模量关系不大，而随着表面垂直载荷的增大而减小；平板牵引过程中台车牵引力和仿生曲面控制节点垂直方向位移基本保持不变；利用ANSYS软件对波纹型仿生曲面与土壤的相互作用进行了有限元建模与分析，表明波纹型仿生曲面系数在一定范围内基本不受土壤弹性模量的影响，随着波纹型仿生曲面突起宽度、两相邻突起间距以及表面垂直载荷的增大而减小，但在可信度为90％的前提下，三个因素影响都不显著；首次将波纹型仿生曲面应用于与土壤作用方式以挤压为主的螺旋桩，形成仿生螺旋桩，并与普通螺旋桩进行了沉桩对比试验，表明波纹型仿生曲面应用于螺旋桩桩体表面具有明显的降阻作用。

It is indicated that the accuracy of the measured value is determined rather by the practical relative error than by the maximum relative error. It is correct that the nearer the scale reading approaches the maximum, the more accurate the measurement is. The scale reading need not be required above 2/3X.

指出使用电表进行测量时，测量值的准确性是由其实际相对误差而非最大相对误差决定的；并非电表的读数越接近满刻度，测量值的准确性就越高；使用电表进行测量时，电表的读数不必被限定在2/3X上。

Age is a relative thing; you're young as long as you have a relative who is older.

年龄是相对的；只要你有年长的亲戚，你就年轻。

Complications arise when relative age and relative rank are not both the same.

当年龄和地位不全一样时就会非常复杂。

Complications arise when relative age and relative rank are not both the same.

刚到医院的年轻的医生会觉得称呼较老的医生很难拿，他们地位相同，可以用名字，但是年龄上的巨大差异又要叫他的身份。

Both three systems showed low abundance of herbivorous fishes. Relative abundance of fishes and coral reefs was least in the anthropogenically impacted systems. However, relative abundance of fishes did not differ in the protected and non-protected systems, suggesting the little effect of marine protection area.

而受人为活动影响的珊瑚礁生态系则显示，破坏的保护区之鱼类和珊瑚比例最少，但藻类最多；然而鱼类比例在保护区和非保护区间，除非是受到高度管制的保护区，鱼类比例会较高外，二区间的鱼类比例差异并不大，显示保护区可能未受到较妥当的保护，无法发挥其效能。

The results showed that the antlions fed on M. domestica larvae obtained significantly higher body weight, pupal weight, relative growth rate and pupation percentage, and significantly shortened larval duration when compared with the antlions fed on S. litura and S. exigu larvae. When feeding on C. cephalonica larvae, antlions had similar body weight, pupal weight and pupation percentage, but significantly decreased relative growth rate and prolonged larval duration, than those fed on M. domestica larvae.

结果显示，用家蝇幼虫饲养的蚁狮，其体重增长、相对生长率、化蛹率、蛹重均显著高于用斜纹夜蛾和甜菜夜蛾幼虫饲养的蚁狮，而幼虫历期则比斜纹夜蛾和甜菜夜蛾幼虫饲养的短；用米蛾幼虫饲养，虽然蚁狮体重增长、化蛹率和蛹重与用家蝇幼虫饲养的差异不显著，但其相对生长率却显著低于用家蝇幼虫饲养的蚁狮，幼虫历期也比用家蝇幼虫饲养的明显延长。
