| 摘 要： | 提出了描述颗粒白细胞粘弹性的三参数粘膜模型，采用用微管吸吮实验技术，将此模型用于大鼠单个颗粒白细胞粘弹研究，结果表明用三参数粘性模型能较好地描述颗粒白细胞发生小变形的粘弹性特征，克服了惯用的标准固体模型描述颗粒白细胞发生小变形时初始变形为弹性响应的假设。

| Abstract: | In this paper, a new viscoelastic model for granulocytes was introduced. The stress was placed on the theory and its experimental results of three parameter viscous model with micropipette aspirating technique. The small deformation of single rat granulocyte into the micropipette was analyzed by the model. Within the small deformation, the fit of the experiment data using the three parameter viscous model was more satisfactory than that using the standard solid model, and the former suggested that cytoplasm of granulocyte was treated as a liquid rather than a solid. |
