Abstract
The diffusion coefficient of potassium ion (DK) in frog muscles was studied by a new method. In normal cytoplasm DK averaged one-eighth of the value in the free solution. Arrest of metabolism or injury caused an increase in DK. In muscles killed with iodoacetate, DK rose to three-quarters of the value in free solution. The data support the association-induction hypothesis.
摘要
采用一种新方法研究了蛙肌中钾离子的扩散系数（DK）。在正常细胞质中，DK平均为游离溶液中该值的八分之一。代谢停止或损伤会导致DK增加。在用碘乙酸杀死的肌肉中，DK升至游离溶液中该值的四分之三。这些数据支持关联诱导假说。
