最近发现，轻离子输运行为具有显著的标度特性，可用一个称为标度输运截面的参数来标定。本文利用这个重要的性质，给出了以标度输运截面为自变量的轻离子粒子数反射系数和能量反射系数的普适拟合公式。此公式具有非常好的单值对应关系，相比之下，经常应用的约化能ε作为标度参数的反射公式，因其分散度大而相形见绌。 It has recently been found that light ion transport behavior has significant scale characteristics that can be calibrated using a parameter called the scale transport cross section. In this paper, by using this important property, we present a universal fitting formula for the reflection coefficient and the energy reflection coefficient of light ion particles with the cross-section of transport as a standard. This formula has a very good single-value correspondence, in contrast, often used to reduce the ε as a scale parameter reflection formula, due to its dispersion and dwarfs.
