The numerical simulating result: When the intensity of driving pulse current is lower than 14, phase resetting is odd resetting,otherwise, it appears even resetting.

本文应用Beeler-Reuter模型,选取损伤电流I=23μA,产生自发振荡,施加不同强度的电流脉冲刺激,研究窦性起搏对心室肌纤维自节律位相重置的过程,结果表明:当外加电流脉冲强度小于14时,体现位相奇重置,反之,体现位相偶重置,并给出位相重置函数。

It is indicated that optimal minimum odd weight column codes can correct or detect effectively the errors of the bus data in the embedded system,and it can improve the reliability of the system.
