摘　　要：将长直螺线管磁场看作直线电流磁场和圆线圈电流磁场迭加。在此基础上 ,对螺线管磁场进行了深入分析和精确计算 ,给出了一般情形下近似描述长直螺线管磁场需满足的结构条件。Decomposing the magnetic filed of a current carrying strainght solenoid into that of straight current and that of circular current , deep analysis and exact calculation of the field are proposed, and the approximation conditions have been derived for the description of the magnetic field of a straight solenoid in simplified case.
