摘要: 基于达朗贝尔公式,讨论了半无界弦自由振动时的非齐次边界条件的延拓问题.结果表明:对半无界弦自皂振动时的非齐次边界条件的延拓,理论上可有多种方法,尽管延拓表达式不同,但不会影响最终结果.文中最后还给出了两种相对简单的延拓方法.

关键词: 非齐次边界条件, 延拓, 自由振动

Abstract: Based on d'Alembert formula, the extension of inhomogeneous boundary condition on free vibration of semi-boundless string is discussed. The results show that there are many extension methods, although extension expressions are not the same, but the same final results do. Two simple extension methods are given.

Key words: inhomogeneous boundary, extension, free vibration
