摘　　要：本文导出了各种坐标系下梁的挠曲线微分方程，并以实际算例进行了积分计算。计算结果表明，梁的挠曲线微分方程必须与选取的坐标系相适应，否则将导致错误的结论。The paper derives the differential equatioiis of the space curve about beam indifferent coordinate systerns and completes the practical computations by taking a simpleexample. The results show that the differential equation must be suited to the coordinatesystem,Otherwise it will result in the wrong solution.
