Magnet, which can offer adsorbability enough to keep the robot working on the vertical walls, is kept close to the outside surface of the pedrails. Front-wheel driving is adopted as the driving system and the two front-wheel are drived by two elctromotors, respectively. When the two motors are running with the same direction, the robot walks straightly. When the two motors are running with the contrary velocity, the robot can swerve.

本文设计的压力容器检测爬壁机器人采用履带式移动机构，双履带构成爬壁机器人的基本框架；采用永磁吸附方式，将永磁片贴在履带的外表面，可提供足够大的吸附力，结构简单；采用前轮驱动，两个驱动轮分别由电机驱动，当两电动机转速一致时，机器人沿直线行走，当两电动机差速时，可实现爬壁机器人整体转弯。

In-line skating jump landing was similar to stop-jump landing. Stop-jump consists of a 2-3 steps approach run and a two-footed landing followed by two-footed takeoff to maximum height and two-footed landing again. However, no study has been involved to investigate the second two-footed landing after the takeoff.

直排轮跳跃著地动作与双脚急停跳跃著地相当类似，双脚急停跳跃是在两到三步的跨步助跑后，以双脚著地后立刻起跳，跳至最高后再以双脚著地。

Finally, stochastic vibration analysis of a two-floor frame structure by blasting seismic action is done by finite element program ANSYS. In order to contrast, that by nature seismic action is also done here, and displacement field, velocity field and stress field of this two kind of condition are obtained, and differences of the structure damage mechanics by two kind of action are analyzed. Dynamic reliability analysis of the two-floor frame structure is done using of simulation results, obtaining the safe reliability level of the structure by seismic action, and seismic safety evaluation of the frame is completed.

最后，运用有限元程序ANSYS对爆破地震动作用下一个两层框架结构进行了随机振动分析，为了进行对比，这里也对结构受天然地震动作用进行了随机振动分析，得到了两种地震动作用下结构响应的位移场、速度场和应力场的变化情况，分析了爆破地震动和天然地震动对建筑结构物破坏机理的不同；应用数值模拟的结果对该两层框架结构进行了动力可靠性分析，得到了其在地震动作用下的安全可靠度，完成对该框架的爆破地震安全性评估。

This chapter provides a mathematic model for the transformation between two images obtained from the same scene. Based on pin-hole camera model, the relationship between the coordination of two images is discussed using two camera models, and it is proved that geometric relationship of two images obtained from one scene satisfies affine transformation.

论文在透视投影成像模型基础上，用两个不同相机在不同位置对空间中同一点成像，推导出对应点在不同图像中像素坐标之间的解析表示形式，证明了像素坐标之间满足仿射模型，同时分析了图像之间满足仿射模型时应具备的条件。

Cable .Make use of this principle, we can quickly locate the target cable or break point from large amount of cables, under carpet, the inner of decoration wall and over ceiling1 operation is simple , reliable , the interface is nimble , use is broad , bionic form , carry-over are convenient, since our link tester has two signal output port, it can work when switch is running, this is very convenient. 2 applies to all metal cable such as network cable , tele phone line cable , video cable , automobile circuit .it can not be work with high voltage(above 80V),if you want to locate it ,please turn off the cable power supply3 can test the telephone line polarity, connectedness, rough position of breaking point.4 uses the two crocodile clamp to avoid getting rid of the job of make network cable. Use the RJ45/RJ11 interface can connect to the network and the telephone line directly.5 link tester can find out that pair of circuit line cable from large mount of cables. 6 high amplitude ranks 200 times amplification circuit is sui table to locate long distance cable.7 two-sided network lines sequence indicator is easy to examine the network line cable whether or not correctly conveniently. 8 portable types multifunctional bag can encase most of your engineering tools; remit your messy carry-over of implement bothering. 9 adopt two 9V batteries.
