对机械网络理论和四端参数法在振动与隔振分析中的应用进行了研究，指出了经典刚性隔振理论对振动系统简化时的局限性。研究表明，用四端参数法可以较为简洁地解决一些经典隔振理论所难以解决的问题 The application of mechanical network theory and four-terminal parameter method in vibration and vibration isolation analysis is studied, and the limitation of classical rigid vibration isolation theory to vibration system is pointed out. Research shows that the four-terminal parameter method can be more concisely solve the problems that classical isolation theory can not solve
