| 摘 要： | 当带电体的电荷分布具有某些特殊对称性时,电场强度分布也具有一定对称性,选择合适的闭合积分曲面即高斯面,就可用高斯定理计算电场强度.应用高斯定理对球对称分布带电体求解电场强度,能加深对高斯定理应用范围及其使用方法的理解.

| Abstract: | When the distribution of electric charge is symmetrical in some way,the distribution of electric field intensity is symmetrical also.Through selecting a suitable integral surface,the electric field intensity can be computed.The electric field of a charged body with spherically symmetric distribution was solved by Gauss theorem.Through this way,we can comprehend the range of application and usage method of Gauss theorem much well. |
