Two light-scattering techniques are used to study the temperature dependence of translational and rotational motility in Escherichia coli. The method of number fluctuation spectroscopy is developed theoretically and experimentally to measure the translational swimming speed of a smooth swimming strain of E. coli. Interference fluctuation techniques are used to study the rotational component of the motion. The results demonstrate that the thrust remains proportional the the torque generated by the flagella throughout the range studied and also show that relative changes in translational swimming speed may be inferred from the dynamics of rotational motion.
采用两种光散射技术研究大肠杆菌平移和旋转运动的温度依赖性。从理论和实验上开发了数量涨落光谱法，以测量大肠杆菌光滑游动菌株的平移游动速度。利用干涉涨落技术研究运动的旋转分量。结果表明，在所研究的整个范围内，推力与鞭毛产生的扭矩保持正比关系，并且还表明，可以从旋转运动动力学推断平移游动速度的相对变化。
