阻尼振动与稳态受迫振动的能量

Energy of Damped Vibration and Steady Forced Vibration

定量分析了阻尼振动、稳态受迫振动的能量随时间变化的关系.这有助于更深入地理解它们的内在规律,特别是指出了稳态受迫振动虽为等幅振动,但通常在一个周期内振动能量将随时间改变.从而澄清某些教材在叙述这方面问题时不够准确之处.

This essary quantitative analyse energy in damped vibration and steady forced vibration each other time. It contribute to understand go a step further its inner law. And point out emphatically：although steady forced vibration is the same amplitude of vibration, but vibration energy usually changes follow time in a period. So clear up unaccurate problem in some textbook narrate party.
