flash time meaning in Chinese

闪光时间

The result shows that the new control system has convenient parameter modification , perfect controlling flexibility , rapid dynamic response speed , stable welding procedure ; the das of welding parameters has strong ability of anti - disturbance and the data is reliable . the control effect and practicability of the diagnosis system judging the welding quality are both good by using the characteristic values of welding process such as the percentage of the flashing time . gray - spots flaw in flash welding joints of rail is the least when the pole moves to and fro at the same velocity and the speed is slow
结果表明：新型控制系统参数设置修改方便，控制柔性好，动态响应速度快，焊接过程稳定；焊接参数采集系统抗干扰能力强、数据可靠；以闪光时间百分比等焊接过程特征量为判据诊断焊接质量效果好，实用性强；当动立柱的前进、后退速度相同且为低速时，钢轨接头中灰斑缺陷数量最少。
