摘要
《理论力学》静力学中的静定或超静定问题的判定不仅与独立平衡方程个数与未知量个数的比较有关,还与约束类型相关;与自由度的关系并没有确定的判据。
The determination of statically determinate or statically indeterminate problem in Statics is not only related to the comparison between the number of independent equilibrium equations and the number of unknown quantities,but also to the type of constraint,and there is no definite criterion for the relationship with degrees of freedom.
