A novel cable climbing robot applied to cable maintenance was introduced. It is centered orientable wheel-based, omni-directional cable climbing robot. The climbing mechanism of the robot and its working process were described. The driving force needed was analyzed, and the critical force needed for maintaining robot staying cable was calculated. The eccentricity allowed between center of robot and cable axis when the robot moving on inclined cable was discussed, and the least eccentric magnitude was calculated.

Heilongjiang mélange distributed in Yilan area of Heilongjiang Province is regarded as the tectonic mélange with features of suture zone. Some metam orphic basic lavas consisting of quite a few metamorphic minerals without directional characteristics are named massive blue schist.

黑龙江省依兰地区分布的黑龙江杂岩被认为是具有缝合带性质的构造混杂岩，其中所含变基性火山熔岩中含有的变质矿物不具有定向组构特征，因此称之为块状蓝片岩。

Through S-wave polarization scanning mode of ultrasonic impulse testing, rock samples with three different properties are measured to evaluate the variation of S-wave velocity in three perpendicular coordinates. By analyzing S-wave splitting of three directions and polarization of the maximum or minimum speed S-wave amplitudes, we think that the velocity orthotropy and fracture orientation observed in the grain sandstones and crack marble samples can be estimated in terms of the polarization and velocity of S-wave. Also, perpendicularity characteristics on the two types of rocks can attribute to the bedding and structure of rocks (directional grains or crystallize).

在实验室通过选择了三种不同岩性的岩石，采用超声脉冲测试方法中的横波偏振扫描方式，观测了岩石样品三个坐标方向上的横波速度变化，通过分析三个传播方向上出现横波分裂的差异，以及出现最大或最小快慢横波振幅的偏振方向发现，可从横波偏振方向和速度值判断出纹理砂岩和裂隙大理岩样品存在不同程度的速度正交各向异性和裂隙方向等特征，认为这两种岩石的正交特性的原因是岩石的层理或裂隙与岩石本身的结构构成的。
