| 摘 要： | 对包含受外力作用的两体系统中的一体相对另一体的具体问题计算,往往较复杂.在折合质量的基础上通过引入“折合力”来建立两体中的一体相对运动的动力学关系,能使有外力作用下的两体系统中的一体相对另一体的问题计算变得简单.

| Abstract: | It is often more complex to calculate the specific issues about one body relative to the other in a two-body system that get the external force.Some dynamic relations can be created by introducing the equivalent force to that system after introducing the equivalent mass,so that calculation is very simple. |

| Keywords: | two-body system equivalent mass equivalent force force kinetic energy |
