在普遍的跷跷板机制的上下文中，“在左右对称模型的框架内实现，我们讨论了一个特殊的计划，它允许确定的Kobayashi-Maskawa矩阵元素的夸克质量。通过考虑{ital V}{sub {ital u}{ital s}}和{ital V}{sub {ital c}{ital B}}的实验值，我们得到了对奇异夸克和顶夸克质量的约束.在对规范玻色子部分进行了简要的讨论之后，我们还证明了在模型中出现的改变味道的中性流规范相互作用被安全地抑制，并且不会引起与已知实验极限相冲突的影响。
In the context of the universal seesaw mechanism,'' implemented in the framework of left-right-symmetric models, we discuss a particular scheme which allows the determination of the Kobayashi-Maskawa matrix elements in terms of the quark masses. By taking into account the experimental values of {ital V}{sub {ital u}{ital s}} and {ital V}{sub {ital c}{ital b}}, we obtain constraints on the strange- and the top-quark masses. After a brief discussion of the gauge-boson sector we also show that the flavor-changing neutral-current gauge interactions which arise in the model are safely suppressed and do not give rise to effects in conflict with the known experimental limits.
