The dielectric spectroscopy of the skeletal muscle cells is approached by extracellular perfusion, using curve fitting and numerical calculation with nonlinear Cole-Cole equation, and the dielectric parameter of skeletal muscle cells is compared after perfusion, The results show: (1) the permittivy at low frequency (epsilon1) and the conductivity at hight frequency (kappa(h)) reduces in keeping with extracellular perfusate; (2) the effect of extracellular perfusion on the characteristic frequency (f(c1),f(c2)) is small; (3) the extracellular perfusion mostly influences the peaks of deltaepsilon" and tgdelta for the skeletal muscle cells.
通过细胞外灌注、使用曲线拟合以及非线性科尔-科尔方程进行数值计算来研究骨骼肌细胞的介电谱，并在灌注后比较骨骼肌细胞的介电参数。结果表明：（1）低频电容率（ε1）和高频电导率（κ(h)）随细胞外灌注液而降低；（2）细胞外灌注对特征频率（f(c1)，f(c2)）的影响较小；（3）细胞外灌注主要影响骨骼肌细胞的δε"和tgδ峰值。
