中文摘要：本论文主要研究了微分方程中的一类很重要的方程组——拟线性方程组，它是微分方程的一个重要的课题，常常出现在流体动力学、半导体设置的物理理论、化学反应理论、工程、生物、通信和生态等研究领域中。

We investigate phenomenologically effects of the flavor-dependent quarkonia annihilation on the meson-meson mixing, and find that corrections due to the flavor-dependent quarknoia annihilation can be described by the constituent quark masses in the mixing model which holds for all the meson nonet. We also study the relation between Regge trajectory and meson spectrum, and therefore concluded that the quasi-linear Regge trajectory with the requirements of additivity of intercepts and inverse slopes can describe the meson spectroscopy with good accuracy, and it also holds for the radial excited mesons except for the bbbar mesons.
