摘　　要：已建立的渗透性模型主要基于连接蛋白的开关特性,却忽略实际蛋白间的差异,在应用上存在局限.从连接蛋白生物特征多样性的角度引入渗透率这一缝隙连接类型参数,对渗透性模型进行改进,分析渗透率对分子通信的时延、传输距离等参数的影响.选取钙离子为传输粒子进行仿真,实验结果验证了模型的准确性,在发送、传输条件一致的前提下,渗透率越高,接收钙离子波的幅度越大,对应的传输距离越远.The established permeability model is mainly based on the switching characteristics of connexin but ignores the differences between the actual proteins,which has limitations in application.The penetration rate is introduced from the perspective of the biological diversity of connexin,and the permeability model is improved to analyze the influence of penetration rate on parameters such as the time delay and transmission distance of molecular communication.Calcium ions are selected as the transmission particles for simulation.The experimental results verify the accuracy of the model.Under the premise of the same sending and transmitting conditions,the higher the penetration rate is,the larger the amplitude of the received calcium ion wave,and the longer the corresponding transmission distance is.
