摘　　要：把用在建筑环境工程的“隔声质量定律”应用在建筑降噪排水管的研制上,对降噪排水管的材质选择、管壁结构设计等起到了很好的指导作用;还从原子分子论的微观结构和经典力学理论出发,较好地解释了“隔声质量定律”,探讨了该定律较深的理论意义,并用该定律评价了目前国内外一些降噪排水管的降噪效果。The application of ＂sound-proof mass law＂ which was used in the building environment engineering could guide the selection of raw materials for noise-reducing drain pipes and the design of pipe wall structure very well. Based on the atomic and molecular microstructure theory and the classical mechanics theory, the ＂sound - proof mass law＂ was better explained. The deep the- oretical meaning of this law was investigated. The noise-reducing effects of some noise - reducing drain pipes made abroad and in China were evaluated according to this law.
