铜响打击乐器中有主要为交响乐队用的军镲、吊镲和主要为民族戏曲用的锣、钹、铙、镲。两者在工艺和声学上存在共同的问题,但在特点要求上有根本区别,我们在后面分别地具体讨论。从已做过的工作来看,铜响器从合金材料的配方、冶炼到成型工艺、热处理等,在宏观、微观机制上都有很多新的问题提出来可供我们深入研究。但首先遇到的问题是:什么是我们对乐器所要求的音质?其次才是怎样才能控制上述所有工艺使它达到我们所要求的音 Copper ring percussion instruments are mainly used by the symphony orchestra, condolences and mainly for national drama gongs, cymbals, 铙, 镲. Both have common technical and acoustical problems, but are fundamentally different in their characterization requirements, which we discuss separately later. From the work done, copper ring from the alloy material formula, smelting to the molding process, heat treatment, etc., in macroscopic and micro mechanisms have many new questions put forward for our in-depth study. But the first problem we encountered was: What is the sound quality that we need for the instrument? And what next is how to control all the above processes so that it meets the tone we want
