Elastic properties of canine vocal fold tissue (muscle and mucosa) were obtained through a series of experiments conducted in vitro and were modeled mathematically. The elastic properties play a significant role in quantitative analysis of vocal fold vibrations and theory of pitch control. Samples of vocalis muscle and mucosa were dissected and prepared from dog larynges a few minutes premortem and kept in a Krebs solution at a temperature of 37 +/- 1 degrees C and a pH of 7.4 +/- 0.05. Samples of muscle tissue and mucosa were stretched and released in a slow, sinusoidal fashion. Force and displacement of the samples were measured with a dual-servo system (ergometer). After digitization, stress-strain data for samples of muscle tissue and cover tissue were averaged. The stress-strain data were then fitted numerically by polynomial and exponential models.
通过一系列体外实验获得犬类声带组织（肌肉和黏膜）的弹性特性，并进行数学建模。这些弹性特性在声带振动的定量分析和音高控制理论中起着重要作用。在犬类濒死前几分钟从其喉部解剖并制备声带肌和黏膜样本，将其置于温度为37±1摄氏度、pH值为7.4±0.05的 Krebs 溶液中。肌肉组织和黏膜样本以缓慢的正弦方式拉伸和释放。用双伺服系统（测力计）测量样本的力和位移。数字化后，对肌肉组织和覆盖组织样本的应力应变数据进行平均。然后用多项式和指数模型对应力应变数据进行数值拟合。
