提出了分子马达能量效率的有效温度表达式，有效温度是根据相关函数与速度敏感性之比来定义的。我们还对热棘轮模型给出了关于该温度的数值结果。此外，我们使用已知的驱动蛋白值来表达效率可以充分解释实验结果。这里提出的框架在现象学上具有封闭的形式，并且独立于任何详细的模型。
An expression for the energetic efficiency of a molecular motor is presented in terms of an effective temperature, which was defined based on the ratio of the correlation function to the susceptibility of its velocity. We also present a numerical result regarding this temperature for a thermal ratchet model. Furthermore, our expression of efficiency using known values for kinesin can adequately explain the experimental results. The framework presented here has a closed form phenomenologically, and is independent of any detailed models.
