Thermoelastic properties of cross-bridges were measured by application of small sinusoidal length perfurbations and submillisecond Joulean temperature jump to chemically skinned muscle fibre removed from rigor solution. The thermal expansion coefficient of fibres was 4.2 +/- 1.0 X 10(-5) K-1. We have observed neither rubber-like stiffness increase, nor tension increase and stiffness decrease (which are expected if alpha-coil melting occurs) after temperature jump.
通过对从僵直溶液中取出的化学去膜肌纤维施加小的正弦长度扰动和亚毫秒级焦耳温度跃升，测量了横桥的热弹性特性。纤维的热膨胀系数为4.2±1.0×10⁻⁵K⁻¹。在温度跃升后，我们既未观察到类似橡胶的刚度增加，也未观察到张力增加和刚度降低（如果发生α-螺旋熔化，预计会出现这种情况）。
