生物媒质组分定征中声速混合定则的比较

Comparison on the mixture rules of sound velocities used in characterizing biomedium components

本文分析研究了各种声速混合定则的异同,以及这些定则在预言生物媒质组分含量时的有效性.分析计算表明,各种声速定则对实际生物媒质声速的模拟符合程度有所差异,在一定条件下这些定则是兼容的;尚没有能完整描述生物媒质声速特征的统一的、最佳模拟定则。

In this paper, several mixtrue rules of sound velocity and their usefulness in characterizing the components of biomedium are analysed. It is pointed out that for characterizing the components of biomedium, the rules are compatible with each other under cartain conditions, and the errors between each rule and real sound velocity are different. It concludes that there is no general rule suitable for various media among above rules.
