The dynamic Young's modulus E' and loss modulus E'' were obtained for isolated bovine cornea using a direct-reading dynamic viscoelastometer. Within the temperature range (0-60 degrees C) and frequency range (3.5-110 Hz) studied, both moduli were temperature and frequency independent. The dynamic birefringence of the cornea was measured in a special apparatus designed for this purpose in conjunction with the dynamic viscoelastometer. The stress-optical and strain-optical coefficients as well as the corresponding phase angles were evaluated as a function of temperature and frequency. The strain- and stress-optical coefficients were both temperature and frequency dependent.
使用直读式动态粘弹性仪测定了分离的牛角膜的动态杨氏模量E'和损耗模量E''。在所研究的温度范围（0至60摄氏度）和频率范围（3.5至110赫兹）内，这两个模量均与温度和频率无关。角膜的动态双折射是在为此目的专门设计的特殊仪器中与动态粘弹性仪结合测量的。评估了应力光学系数和应变光学系数以及相应的相角随温度和频率的变化情况。应变光学系数和应力光学系数均与温度和频率有关。
