Bohr's orbit radius has nothing to do with reducedmass.
玻尔轨道半径与折合质量无关。

Use of electron mass instead of the reducedmass to calculate the ground-state energy of the hydrogen atom gives-13606ev which is in error by7parts in13000.
用电子质量代替折合质量去计算氢原子基态能量给出- 13606电子伏,误差是13000分之7。

The reduced kinetic energy is discussed using the reducedmass of the constrained two bodies. Then a simple method to solve the constrained two bodies problem is presented.
