| Abstract: | A frequently neglected problem in harmonic oscillation analysis is pointed out, and simple analysis methods and solutions for some given oscillation systems are given. Some basic conclusions, such as the kinematic properties of a given oscillation system is independent on the origin of the selected coordinate system, the energy conversation of the system is independent on the selected referent zero-level of potential energy, are further confirmed. |

| Keywords: | harmonic oscillation equilibrium position conversation of energy origin of coordinate potential energy |
