论文摘要
Riccati方程方法用于为两个线性一阶普通微分方程的系统建立新的比较定理。该结果基于“ null-classes”的A，所谓的概念，并且是Sturm比较定理的概括。
The Riccati equation method is used to establish a new comparison theorem for systems of two linear first order ordinary differential equation. This result is based on a, so called, concept of "null-classes", and is a generalization of Sturm's comparison theorem.
