我们研究了热带PSI类的热带重/轻Hassett空间的交集，推广了Kerber-Markwig的结果，热带模空间的有理稳定曲线与不同的标记点。计算结果表明，交集中极大锥的权具有关于其下热带曲线的组合解释，且总是非负的。特别是，我们的结果专门，在顶部维度，热带交叉产品与其经典的对应。
We study the intersection of tropical psi-classes on tropical heavy/light Hassett spaces, generalising a result of Kerber--Markwig for tropical moduli spaces of rational stable curves with distinct marked points. Our computation reveals that the weight of a maximal cone in an intersection has a combinatorial intepretation in terms of the underlying tropical curve and it is always nonnegative. In particular, our result specialises to that, in top dimension, the tropical intersection product coincides with its classical counterpart.
