摘　　要：电极向靶运动速度的测量精度和可靠性是研究放电参数与电极运动速度关系的基础。基于实测数据,为日本小野PS-600/700测试系统的加速度计设计校正方法,提出一种准确的经验公式并加以验证,为带电人体手握金属小棒电极,以一定速度向靶放电过程中,电极速度与放电强度参数相关性研究提供了前提条件。研究结果表明,放电电极相互接近的速度与放电电流峰值、放电电流上升斜率峰值具有强正相关性,而与放电弧长则有强负相关性。带电体电压小于300V时电极速度影响可不考虑。Analysis of correlation between approach speed and intensity of electrostatic discharge （ESD） relies on accuracy and reliability of electrode speed measurement. A calibration method based on experiment data was designed and employed for an acceleration-meter. An empirical calibration formula was proposed. Correlation investigation of discharge parameters was performed on electrode approach speed with basic data measured by a calibrated acceleration-meter in electrostatic discharge from a charged human-body. Research results show that strong positive correlation exists between approach speed and peak discharge current as well as peak discharge current slope, while strong negative correlation exists between approach speed and spark arc length. The effect of approach speed can be neglected for Vc 〈 300 V.
