本文利用新研制的测量系统对声带和脑室皱襞的应力-应变关系进行了实验分析。声带中膜部的僵硬程度低于前连合或声带突附近。与声带相比，心室襞的僵硬程度要低得多，而且明显更粘稠。在声带膜质部分，自由缘上下2mm处的僵硬程度比自由缘本身小，黏度大。
The viscoelasticity of the vocal and ventricular folds was experimentally assessed by analyzing the stress-strain relationships obtained using a newly developed measuring system. The degree of stiffness of the mid-membranous portion of the vocal fold was less than that near the anterior commissure or the vocal process. The ventricular fold was much less stiff and significantly more viscous than the vocal fold. At the membranous portion of the vocal fold, the degree of stiffness was less and that of viscosity greater at 2 mm above and below the free margin than at the free margin itself.
