| 摘 要： | 通常在讨论均匀带电体绕对称轴转动时的转动惯量及其在外磁场中所受磁力矩时，要用到较多的微积分知识，给这类问题的求解带来一定难度。文章提出运用量纲分析的方法可以避免复杂的数学运算，突出了定性与半定量物理思想，并较为简洁的得到结果。

| Abstract: | Infinitesimal calculus is too often used when it comes to the revolving inertia and the di mensional solution of evenly electrified bodies revolving the symmetrical axis or under magnetic matrix in the outer magnetic field.Thus it bringd a lot of difficulties to the solution of this kind of prob ferns.By emphasizing the qualitstiveness and half-quantiveness,this paper proposes the dimensional analysis so as to avoid the complicated calculation and works out the result in a simpler way. |
