(34)使用的单位是无量纲的。它们对应于一个系统，其中碳原子的质量，CC键的长度l和kBTnf，其中Tn<= 600 K，都是1。以cgs为单位，St = 1对应于7.51 × 10~（10）s，系数1对应于2.67 × 10~（10）dyn/（cm·s~ 1）。请注意，这个系数，在朗之万方程中乘以原子速度以产生作用在其上的摩擦力，不是溶剂粘度μ;它是从后者通过斯托克斯定律，= 6 μ，其中o是有效原子半径的关系获得的。
(34) Units used are dimensionless. They correspond to a system where the mass of a carbon atom, the lengthl of a CC bond, and kBTnf, where Tn<= 600 K, are all unity. A St of 1 corre-sponds to 7.51 X 10~ Í4 s and a value of the coefficient of 1 corresponds to 2.67 X 10~ 10 dyn/(cm s~ l) in cgs units. Note that this coefficient, which multiplies atom velocity in the Langevin equation to yield the frictional force acting upon it, is not the solvent viscosity µ; it is obtained from the latter by a relation such as Stokes’ law,= 6 µ, where o is an effective atomic radius.
