1.研究了青蛙离体肌纤维在等长（“固定端”）强直松弛过程中肌节长度和张力的变化。肌节长度通过测量用He-Ne激光照射小段纤维产生的衍射图案中零级至一级强度最大值的分离来计算。使用“条纹”摄影法在电影胶片上连续记录衍射光谱。
1. A study has been made of changes in sarcomere length and tension which occur during relaxation from isometric (‘fixed ends’) tetani in isolated muscle fibres of the frog. Sarcomere lengths were calculated from measurements of the separation of the zero‐to‐first‐order intensity maxima in diffraction patterns generated by illuminating small segments of fibre with a He—Ne laser. Diffraction spectra were recorded continuously on cine‐film using the method of ‘streak’ photography.
