| 摘 要： | 在蟾蜍坐骨神经-腓神经观察了温度和麻醉对几种兴奋性指标的影响。结果表明,标准电量(a)随兴奋性的变化而有规律地变化。兴奋性愈高。a值愈小。而Weiss式中的b、基强度(Rh)、时值(Chr)及强度—时间曲线均不能正确反映兴奋性。细胞膜时间常数(RC)与兴奋性的变化无规律性联系。结论,a是兴奋性的可靠定量指标。

| Abstract: | Effects of temperature and anesthesia on various excitability indexes of sciatic—peronael nerve were observed in toads. The results show that standard electrical quantity(a) changes regularly with the change of excitability. The higher excitability, the less the "a" value. But "b" in Weiss's fomula, chronaxie (Chr), rheobase (Rh), and intensity-duration curve do not indicate excitability. The time constant (RC)of the cell membrane is not related to the changes of excitability. Thus, "a" is an actual index of measuring excitability. |
