本文研究了蛙、龟肌肉等张缩短的作用力与速度的关系。观察到的关系可用希尔S双曲方程(P+a)(v+b)=const满意地描述.等长张力的发展可分析为收缩物质相对于弹性的被动伸展部分的逐渐内部缩短.在青蛙的S缝匠肌中，张力的观测记录与计算结果令人满意地一致.在甲鱼肌肉中观察到了大的分歧，并对其原因进行了讨论.
The relation between applied force and speed of isotonic shortening was studied in frog and tortoise muscle. The observed relation is satisfactorily described by Hill''s hyperbolic equation (P + a) (v + b) = const. The development of isometric tension could be analysed as a gradual internal shortening of the contractile substance against an elastic, passively extending portion. A satisfactory agreement between observed and calculated tension records was found in the frog''s sartorius. In tortoise muscle large divergence was observed, the reasons for which were discussed.
