摘　　要：在介观生物细胞等效电路量子化的基础上通过热正则Bogoliuov变换,研究了有限温度下介观生物细胞中电流和电压的量子涨落。结果表明,介观生物细胞中电流电压的量子涨落不仅与其等效电路的参数有关,还与温度有关,且随时间衰减。Base on the quantization of mesoscopic biological cell equivalent circuit, the quantum fluctuations of voltage and current of mesoscopic biological cell equivalent circuit at finite temperature by Bogoliuov transformation are reported. The result shows that the quantum fluctuations of voltage and current are not only related to the parameters of equivalent circuit, and temperature, but also decay with time. This result may have significant value to the design and application of the bio-electronic apparatus.
