中文摘要：

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．

英文摘要：

When the distribution of electric charge intensity is symmetrical also. Through selecting a is symmetrical in some way, the distribution of electric field 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.
