本文提出了一个基于双相模型的脑粘弹性工作模型，该模型包含了流体通道的分布。描述复刚度（杨氏模量）作为频率函数的关键方程见式（10）、（12）和（32）。在这些方程中，前导项有一个排印上的遗漏，并且缺少幂律指数a。因此，这些方程中的前导项应该是：a (- Iω) a，其中a是弹性常数，I是虚单位，ω是径向频率。指数a可以通过实验推导出来，对许多组织来说，它小于或等于0.2。这些方程式的更正如下。
This paper contains a working model for brain viscoelasticity based on a biphasic model that includes the distribution of fluid channels. Key equations describing the complex stiffness (Young’s modulus) as a function of frequency are found in equations (10),(12), and (32). In these equations, the leading term has a typographical omission and is missing the power law exponent a. Thus, the leading terms in these equations should be: A (− Iω) a, where A is an elastic constant, I is the imaginary unit, and ω is radial frequency. The exponent a can be derived experimentally and for many tissues is less than or equal to 0.2. These equations are corrected below.
