When yielding zone of soil around each anchor superposes highly, anchorage capacity of each anchor could not be increased effectively with increasing number of anchors. Moreover, according to the numerical results of triple anchors ranked in a line, the anchorage capacity of the middle anchor is greater than those of the others result from shearing dilation during anchors pulled out.
在土壤降伏范围高度重叠下,增加地锚支数无法有效提高地锚之锚碇力;本研究更进一步地由三支线型排列的地锚分析中发现,因紧砂受剪膨胀之因素,致使中间地锚之锚碇力有大於外围地锚锚碇力之现象。

The simulation results show that calculated tortuosities varies with network connectivity as well as the Thiele modulus.This work also suggests that tortuosities obtained under diffusion-only conditions can only be used under the strong reaction control conditions.
模拟结果表明,计算出的曲折因子既是孔网络配位数的函数,又随Thiele模数的变化而不同,在纯扩散条件下测得的有效扩散系数只能应用于扩散影响不严重的反应扩散区域。

Methods The net treated by BASF pesticide, the net treated by BASF pesticide after washing twenty times and the net treated by Fendona TM recommended by WHO were used in treated area, and common military nets were selected in the control areas. Aedes vexans, the dominant species in Beiwan, was collected by mosquito aspirators and released into nets. The first knockdown time, medium knockdown time and total knockdown time were recorded, and then compare the knockdown time of 4 kinds of mosquito-net.

The digital simulation of thedynamic processes under step load input and supply oil pressure fluctuation were carried on by MATLAB. Analysis of the dynamic characteristics was done with the changes of the supply pressure, load, structural parameters of spherical hydrostatic bearing and the effective bulk modulus of oil. The conclusions show that structural parameters of the spherical bearing and the effect bulk modulus of oil have significant influence to dynamic characteristics, but the elasticity deformation of interior supporting collet has very small influences on the output response characteristics of the suspension system. The collets deformation can be neglected on the project.
在此基础上,建立了考虑内支撑筒的弹性变形与否时悬浮系统的数学模型,同时,建立了线性化的仿真模型,利用MATLAB对阶跃负载输入和油源压力脉动输入下的系统进行动态过程的数值仿真,结果表明球面副的结构参数,油液的有效体积弹性模数对系统的响应特性有明显的影响,而内支撑筒的弹性变形对悬浮系统的响应特性的影响很小,在工程上可以忽略其弹性变形。
