Studies of the effects of varying tonicity on the contraction of muscle fibres requires a knowledge of the corresponding changes in fibre diameters, if the observed mechanical changes are to be attributed to various factors, including that of the interfilamental spacing. Hitherto, measurements of such changes in fibre diameters involved tedious measurements of the diameters of the fibres at numerous points along its length. We now describe a technique whereby the change in fibre diameter can be deduced from measurements of the corresponding intensity ratio of laser diffraction lines when the fibre is bathed in solutions of differing tonicities.
如果要将观察到的力学变化归因于各种因素，包括丝间间距因素，那么研究不同张力对肌纤维收缩的影响就需要了解纤维直径的相应变化。迄今为止，测量纤维直径的这种变化需要沿其长度在多个点对纤维直径进行繁琐的测量。我们现在描述一种技术，当纤维浸浴在不同张力的溶液中时，可以从激光衍射线的相应强度比测量中推断出纤维直径的变化。
