Reciprocity and unitarity of non-loss linear networks in zero state

在引入强子化时间的重组合模型中，介子（重子）的产率与夸克密度的2（3）次方成比例，保证了演化过程中系统的幺正性。

For the recom-bination model introducing the hadronization time , the production rates for mesons and baryons are proportional to square and cubic of the quark density , this ensures the unitarity of collision system .
