除极化速度 meaning in Chinese

rate of depolarization

Our previous studies demonstrated that agmatine not only reduced the amplitude of action potential ( apa ) , maximal rate of depolarization ( vmax ) , velocity of diastolic ( phase 4 ) depolarization ( vdd ) , and rate of pacemaker firing ( rpf ) , but also prolonged 90 % duration of action potential ( apd90 ) in a concentration - dependent manner
我们先前的实验证明，胍了胺可剂量依赖性地抑制兔窦房结起搏细胞的0相最大上升速度( v _ ( max ) ) ，动作电位幅度( apa )和舒张期除极化速度( vdd ) ，起搏细胞放电频率( rpf ) ，而且能延长90动作电位时程( apd _ ( 90 ) ) 。
