电磁场对高速运动电荷的作用力-洛伦兹力公式的新形式

百年以前，由洛伦兹建立的电磁场对电荷的作用力公式－－洛伦和公式，是在低速情况下得到的，后来被推广到了任意运动速度，本文根据一般电磁场理论信了运动电荷的电磁场特性，认为该公式只适用于低速情况，对高速运动电荷不再适用。并在此基础上导出了适用于任意速度的新的洛伦兹力公式，它在低速情况下转化为通常的洛伦兹力公式。

The force on a high speed moving charge in electromagnetic field-The new form of the Lorentz force formula

One hundred years ago, the formula of force on a charge in electromagnetic field was established by Lorentz in the case of a charge at lower speed. That formula was extended for charge at any speed afterwards. In present paper, the character of electromagnetic field of a moving charge has been discussed by general theory of electromagnetic field. And then a different view has been pointed out, i.e. that formula is only suitable for the case of a charge at lower speed other than that at high speed. The new form of Lorentz Force Formula, that will be suitable for the charge at any speed, has been derived, and it can be transformed into the general Lorentz Force Formula in any case at lower speed.
