摘要翻译：
在本系列的三篇论文中，我们开始研究由0属节点曲线组成的叠的有理Chow环，特别是完全确定了由至多3个节点的曲线组成的子叠的有理Chow环。本文首先构造了有理节点曲线的叠层及其节点分层，并证明了从通用曲线到叠层的映射在格式范畴中是不可表示的。

英文摘要：
  In this series of three papers we start to investigate the rational Chow ring of the stack consisting of nodal curves of genus 0, in particular we determine completely the rational Chow ring of the substack consisting of curves with at most 3 nodes. In this first paper we construct the stack of rational nodal curves and its stratification by nodes and show that the map from the universal curve to the stack is not representable in the category of schemes.
