分析计算了高速投射物对生物体致伤时肌肉组织中瞬时空腔的发展过程；通过将肌肉组织简化为不可压缩的Voigt-Kelvin粘弹性流体模型，在球对称和纯径向运动的假设条件下，应用非牛顿流体力学的基本方程建立了一种计算瞬时空腔发展的理论模型；该模型能较好地反映肌肉组织中瞬时空腔的脉动发展过程以及瞬时空腔内压力的变化，计算结果同实验结果基本一致；通过该理论模型，可以对瞬时空腔进行定量的理论分析和研究.

Analyzes and calculates the process of development of a temporary cavity in the muscle directly after a projectile wounds organisms at a high speed. The muscle is taken as a non-compressible Voigt-Kelvin viscoelastic fluid model, on the assumption of moving in a radial direction and on spherical symmetry, a theoretical model proposed using the basic equations of the non-Newtonian fluid mechanics. The model can well describe the pulsation process of the temporary cavity and changes of pressure in the cavity. The calculated results are in correspondence with the experimental results. The model can be applied in the quantitative analysis of a temporary cavity.
