我们从解析和数值两方面研究了相互作用对生长模型中元素尺寸分布的偏斜度的影响。我们将两种类型的全局相互作用引入到增长模型中，并推导出最初几个时刻的解析表达式，由此计算出大小分布的偏斜度。结果表明，根据耦合符号的不同，相互作用可以抑制或促进尺寸的增长，进而导致偏斜度的减小或增大。变化量随耦合强度的增加而增加，与模型的细节无关。
We study, both analytically and numerically, the interaction effects on the skewness of the size distribution of elements in a growth model. We incorporate two types of global interaction into the growth model, and develop analytic expressions for the first few moments from which the skewness of the size distribution is calculated. It is found that depending on the sign of coupling, interactions may suppress or enhance the size growth, which in turn leads to the decrease or increase of the skewness. The amount of change tends to increase with the coupling strength, rather irrespectively of the details of the model.
