本文在作者推导的增益-损耗平衡方程的基础上，提出了一种改进的静态恢复方法。该方法非常容易在高、中、低速送风管道系统的各种条件下使用。平衡可以得到保证，噪声源——阻尼器——可以减少，总压力损失可以减少，而无需在寿命周期成本上花费更多。引文:ASHRAE Transactions，1983年，第89卷，pt。华盛顿特区2A。

This paper gives an improved static-regain method on the basis of Gain-Loss Balance Equation which the author has derived. The method is very easy to use in various conditions of high, medium, or low velocity supply duct systems. Balance could be ensured, noise sources--dampers--could be decreased and total pressure loss could be cut down without spending more on life-cycle cost.
