| 摘 要： | 对服从欧姆定律和在高场强下不服从欧姆定律的纺织品利用计算机进行数值计算与模拟并进行实验研究.结果表明无论电流密度与电场强度之间为何关系.不同初始场强的衰减曲线都不会发生交叉(Cross-Over)现象,若电流密度不仅与任意时刻的场强有关而且还与初始电场有关则会发生交叉,计算结果预示在某种特殊电场范围内时可能发生双交叉(Double Cross-Over)现象.数值计算结果与实验结果对比显示两者符合得较好.

| Abstract: | The electrostatic field decay characteristic of textile is investigated by numerical computation and experimentation. The results show that the Cross-Over phenomena of decay curves of electric field for different initial field does not occur no matter what relationship between the electric current and the electric field. If the electric current is dependent upon both electric field at any time and initial electric field, the Cross-Over phenomena will be take place. The simulation results show that the Double-Cross-Over phenomena will occur under some special field range for some materials. |
