摘要
利用解析几何原理 ,证明了空间直线的若干性质 ,在此基础上 ,对空间一般力系的平衡方程作了研究 ,并导出了此种力系的 4种新的标量型方程 ,它们与向量型的平衡充分必要条件等价·
Using the principle of analytical geometry, several properties of the space straight line are proved. Based on these properties, the equilibrium of general space force system is considered and its four new scalar_type equilibrium equations are derived which are equivalent to the vector_type necessary and sufficient conditions for equilibrium.
