Digital simulation results show that when a step change in firing angle occurs, the first positive half-cycle time of VC will change suddenly and the subsequent electromagnetic transients appearing in the TCSC circuit will lead to overshoot and oscillations in the TCSC impedance. The range and duration of the oscillation will depend on the synchronization modes used and the manner in which the step change is introduced.

发现脉冲触发角阶跃变小时，电容电压的周期时间也突然变小，使得TCSC的导通角不会随着触发角的阶跃变化而发生突变，而是经过一个振荡过程逐渐达到稳态值，进一步揭示了电容电压同步方式下阻抗阶跃特性会出现过冲和振荡现象的原因。

该装置结构简单，主要由两个楔形光学平板组成，通过电机转动两个楔板可使出射光束方向在一定范围内任意改变，该调节范围由楔板的楔角和折射率决定。

Home position shear tests of slope rock, point loading tests and indoor AMD simulation action tests in XingQiao concave slope had show shearing strength and coherence between body layers of quartz sandstone decrease by 13.2%~21.3% after attacked by AMD, the angle of internal friction between layers is decreased by 5.0%~7.5%, in general, AMD affects the rocks mechanical property at range of 60~100m interior the perpendicular slop. Data analysis shows: 1 The actions to slope are major focused on zone of weakness, shearing strength of slope foot and AMD centre are reduced by 52% and 64.7% separately. 2 The explosion stress wave of long distance field has obviously increasing influence to disturbance amplitude value of slope with increasing of the slope height and distance, the response of the top of slope and fault region are obvious as well as damage effect; the foot of slope is with smallest disturbance amplitude value, the disturbance amplitude value of the step close to free face is obviously bigger than the interior of slope. 3 With the coupling effect of the AMD and explosion loading, the stress distribution inside of slope mainly presents characters of explosion stress field; the area affected by AMD becomes a weak area of shearing stress.
