评述了非相对论量子力学中研究束缚态参数随组分质量和激发能变化的一些方法。这些技术依赖于基本标度参数和半经典（WKB）近似。它们具有普遍的意义，但在这里仅用于研究重夸克和反夸克的束缚系统。夸克间相互作用的性质提取的信息的质量和loptonic宽度的ESTA和Y家庭。它显示了如何一般的方法可以应用到夸克的电荷的测定和预测新的家庭的性质。
Some methods of nonrelativistic quantum mechanics which are particularly useful for studying the variation of bound-state parameters with constituent mass and excitation energy are reviewed. These techniques rely upon elementary scaling arguments and on the semiclassical (WKB) approximation. They are of general interest, but are applied here to the study of bound systems of a heavy quark and antiquark. Properties of the interquark interaction are extracted from information about masses and loptonic widths of the ψ and Y families. It is shown how general methods can be applied to the determination of the electric charge of quarks and to the prediction of properties of new families.
