摘要
根据三串联振子功率流的表达式，对经典统计能量分析（ＳＥＡ）平衡方程进行了修正。修正的ＳＥＡ能量平衡方程中包括了直接和间接结构间的功率流。在满足工程精度的条件下，修正的ＳＥＡ能量平衡方程中的参数可以用经典ＳＥＡ参数来表示。
The energy balane equations in the Classical Statistical Energy Analysis (CSEA) are modified by using the equations of power flow betwe.en the three series coupled oscillators. The modified equations include not only the direct power tlow, but also the indirect power flow. The parameters in the modified equations can be expressed by those in the classical equations when the accuracy of the predicted results is able to satisfy the needs for engineering.
