可弯曲砂轮之特性，特别适用于弧曲及孔曲面之作业。 - Test results indicated : with the hoist of altitude , the increase of ice amount and the rise of pollutant , the average flashover voltage reduced . the character exponent generally depends on the insulator profile , ice amount , ice state and pollution severity etc . by means of a high - speed camera , a data acquisition system and high voltage test facilities , a series of the flashover processes on ice surfaces were record . the experimental results form this study and the subsequent theoretical analyses suggested : the thermal ionization of the air in front of an arc root resulted in arc movement ; the electrostatic force had an auxiliary effect of impelling arc propagation ; the electrical
通过对摄像机、数据采集系统及高压试验装置记录覆冰绝缘子表面闪络电弧的发展过程的试验结果进行理论分析得出：弧根周围空气的热电离导致了电弧的发展，静电场力对电弧的发展起到了加速作用，电击穿仅发生在闪络最终的跳跃阶段；通过测量闪络过程中的放电电压、泄漏电流、闪络时间、覆冰水电导率、电弧长度及电弧半径等参数，得到了不同阶段电弧（电弧起弧阶段、电弧发展阶段及完全闪络）的发展速度、临界电弧长度均随覆冰水电导率的增加而减小。 - One of the stars shall be bigger than the others , with its circumcircle s diameter being 310ths of the height of the flag , and shall be placed in the left ; the four other stars shall be smaller , with their circumcircle s diameter being 110th of the height of the flag , encircling the big star on its right in the shape of an arc
旗面为红色，长方形，其长与高为三与二之比，旗面左上方缀黄色五角星五颗。一星较大，其外接圆直径为旗高十分之三，居左；四星较小，其外接圆直径为旗高十分之一，环拱于大星之右。
