为了让学生理解“建筑力学”中存在的正负号是如何规定的，通过举例分析了“建筑力学”中的正负号问题，得出结论：静力学研究对象是刚体，所以力的投影、力矩、力偶矩的正负号是代表两种可能的运动趋势；材料力学研究对象是变形体，所以轴力、剪力、弯矩、正应力、剪应力的正负号是代表两种可能的变形趋势．

In order to make the students understand provision of plus or minus in ＂Architectural Mechanics＂, plus or minus is analyzed in ＂Architectural Mechanics＂ by way of examples to get, the conclusion that because the statics study object is rigid, so plus or minus is represented by two possible trends of movement, such as the projection of a force, torque and moment of couple and because the material mechanics research object is a deformable body, so plus or minus represents two possible deformation trends, such as the axial force, bending moment, shear force, normal stress and shear stress.
