Based on the mass relation obtained in the framework of meson-meson mixing, with the help of the assumption that for the almost ideally mixing meson nonets, the corrections deduced by the flavor-dependent quarkonia tranistion can be ignored, and the mass of the isodoublet of the 2~3S_1 meson nonet is predicted to be 1584 ( 16.
借助对于接近理想混合的介子九重态,味道有关的夸克偶素间的湮灭效应可以忽略这样一个假定,利用在介子、介子混合框架下导出的质量关系,预言23S1介子九重态中同位旋二重态的质量大约为1584±16。
The key application of the method of analogy in nuclear physics is discussed from the viewpoint of history of physics and methodology,using the theories of nuclear energy level,β decay and meson as example.

In the framework of the meson-meson mixing and the nonrelativistic constituent quark model, it is found that the K(~3P_1) - K(~P_1) mixing angle is about±59°.
在介子-介子混合以及非相对论组分夸克模型两种不同的理论框架下，我们唯象研究了K(~3P_1)和K(~1P_1)的混合，发现它们的混合角大约为±59°，进一步，我们在~3P_0介子衰变模型下给出了K_1(1270)和K_1(1400)的强子衰变宽度，同时我们也给出了关于这两个物理态在τ衰变中的产生比率，对比我们的理论预言和可得到的关于K_1(1270)和K_1(1400)的实验信息显示，目前的实验信息支持K(~3P_1)和K(~1P_1))的混合角为+59°。
