It is understood that part of Matsuura Pylon cable-stayed bridge cables district, a total of 108 cable assembly here, the segments involved in a great ring pre-stress, cable conduit installation, the steel beam positioning gear block anchor Construction of very high precision.

据了解，松浦大桥上塔柱部分是斜拉桥拉索区，共有108根悬索集结于此，该节段所涉及的环向预应力极大、索导管安装、钢锚梁定位齿块的施工精度要求极高。

If no problem, you can check focus on the host graphics card to display if there are problems with connecting cable and plug in the cable guide on the existence of skew fault and its connection with the display card to work closely, and this cable can also connector removed, whether the display facie Xianliang normal or monitor connected to the other hosts to try in order to determine the fault from the host of the site or caused by its own display.

如果无问题，那你可重点检查一下主机显示卡到显示器上的连接电缆是否有问题及电缆上的插头内指针是否存在歪斜断裂及其是否与显示卡连接紧密，另外还可以将这根电缆接头取下，看下显示器是否能正常显亮或将显示器连到其它主机上试试，以此来判断故障的部位是来自主机还是显示器自身所引起的。

So using CFRP cable will be the essential approach to settle the fatigue and corrosion problems of steel cable, and it is one of approaches to increase the span of cable-stayed bridge.

所以采用CFRP拉索将是解决钢拉索疲劳、腐蚀问题的根本途径，是提高斜拉桥跨越能力的途径之一。

It calculates the main cable, suspender and other components in unstressed length, and initial installation location of the main cable and cable clamps.

计算主缆、吊索等部件的无应力长度和主缆、索夹的初始安装位置。

2 Acceptable Curvature Radius:not less than four times of outer diameter of cable,not less than twelve times of outer diameter for copper tape screened cable and armored cable.

3.2允许弯曲半径：不小于电缆外缆外径的4倍，铜带屏蔽及铠装电缆不小于电缆外径的12倍。

Cable core: the cable core is composed of a twisted pair and leakage conductor, with aluminium/plastic compound tape wrapped outside the cable cores.

缆芯：缆芯由一个对绞组及一个泄流线构成，缆芯外重叠绕包铝塑复合带。

Permissible bending radius: not less than 6 times of overall diameter for unarmored cable ; not less than 12 times of overall diameter for armored or screened cable ; not less than 6 times of overall diameter for screened flexible cable .

推荐允许弯曲半径：无铠装层电缆应不小于电缆外径的 6 倍；有铠装层或屏蔽层结构的电缆应不小于电缆外径的 12 倍；有屏蔽结构的软电缆应不小于电缆外径的 6 倍。

By much expriment, this thesis discovers the the vacuation of whole cable insulation can be replaced by that of polymer particles. Then cable insulation is immpregnated by filling SF〓 into cable core.

本文经过大量对比和模拟实验发现，粒料的抽真空浸渍可以代替电缆绝缘的抽真空过程，由于粒料体积小，其抽真空浸渍容易完成；然后再在电缆线芯充SF〓气体对电缆绝缘进行浸渍。

The equations of the towed cable motion are based on Ablow and Schechter model and six degree-freedom ordinary differential equations are used in the analysis of the motion of a towed body. The partial differential equations are discretized by finite difference method and the transient values of towed body depth and cable tension are computed by Newton Iteration when the heave compensation system performs and the length of the cable varies.

拖缆动力学模型基于Ablow and Schechter模型，拖体采用水下运载体六自由度方程模拟，运用有限差分法离散偏微分方程组和牛顿迭代法计算变缆长情况下拖体深度与拖缆各点张力的动态取值。

In order to understand the dynamic property of extradosed cable-stayed, built up its plane continous rigid-frame model and compared with each other, concluded that the former is more complex due to the remarkable coupling effect of cable, pylons and box-girder. The dynamic property of box-girder decide the dynamic property of the bridge, whose whole structure is comparative rigid. This paper indicated that the bridge is not attribute to flexible structure, because its basic free vibration cycle is more shorter than the cable-stayed bridge.

为了更好的理解矮塔斜拉桥的动力特性，还建立了平面梁单元的连续刚构模型，并与平面梁单元的矮塔斜拉模型进行了对比分析，结果表明，矮塔斜拉模型由于索、塔、梁的高阶振型耦合显著，其振型较连续刚构复杂，灵江大桥的动力特性主要由主梁的动力特性决定，其结构整体刚度较大，基本自振周期较斜拉桥短，不属于柔性结构。

The work of this paper is as follows: 1. Looking back the progressing history of the linear motor, introducing the features of the elevator driven by linear induction motor, radicating the topic of this paper "the digital frequency variable control of the elevator bi-side direct driven by linear induction motor". The research of this paper covers the conventional VVVF control, space vector based VVVF control, vector control and DTC.

本文主要开展了以下几个方面的工作： 1 回顾了直线电机发展历史，电机的驱动技术演变，特别是针对直线电机的驱动，简要介绍了直线感应电机驱动电梯的优点和不同结构类型，对传统的v／f控制，基于空间矢量法的v／f控制，矢量控制，和基于电压空间矢量的直接转矩控制进行了比较，确立了本课题的研究主题：直线感应电机双边直推式驱动电梯的全数字变频控制。

The article combines with the treatment of a superficial civil air defense work to introduce how the grouting method to improve the performance of the backfill soil.
