应用矩阵摄动理论、矩阵微分理论、Kronecker代数和矩阵函数的二阶矩技术,提出具有随机传递函数的滤清器的噪声分析方法.在考虑有关大气介质的不确定因素情况下,在时间和空间域内清晰地描述了具有随机传递函数的滤清器的随机响应,并获得了具有随机传递函数的滤清器出声口处随机响应前二阶矩的A计权声级.
應用矩陣攝動理論、矩陣微分理論、Kronecker代數和矩陣函數的二階矩技術,提齣具有隨機傳遞函數的濾清器的譟聲分析方法.在攷慮有關大氣介質的不確定因素情況下,在時間和空間域內清晰地描述瞭具有隨機傳遞函數的濾清器的隨機響應,併穫得瞭具有隨機傳遞函數的濾清器齣聲口處隨機響應前二階矩的A計權聲級.

The method of noise analysis of air-cleaners with random transfer function is presented using matrix perturbation theory, matrix calculus, Kronecker algebra and generalized second moment method.Considering the uncertainty factors of the atmosphere, the random response of the air-cleaner is described clearly in the time and space domain, and the decibel (A) value of the former second moment of random response at the sound outlet of the air-cleaner is obtained.
