论文摘要
我们首先得出了莱维随机环境中两种连续分支过程的整数矩的重复。结果表明，该过程的$ n $第三矩是该过程的初始价值的多项式，最多是$ n $度。在某种自然条件下，还证明了该过程的$ f $ the的标准。
We first derive the recurisions for integer moments of two-type continuous-state branching processes in Lévy random environments. Result shows that the $n$th moment of the process is a polynomial of the initial value of the process with at most $n$ degree. Under some natural condition, the criteria for the existence of $f$-moment of the process are also proved.
