It is known that the Kauffman–Murasugi–Thislethwaite type inequality becomes an equality for any (possibly virtual) adequate link diagram. We refine this condition. As an application we obtain a criterion for virtual link diagram with exactly one virtual crossing to represent a properly virtual link.

某些 v-充分虚拟链路的琼斯多项式的跨度

众所周知，Kauffman-Murasugi-Thislethwaite 类型的不等式对于任何（可能是虚拟的）适当链接图都变成了等式。我们细化这个条件。作为一个应用程序，我们获得了一个虚拟链接图的标准，其中只有一个虚拟交叉点来表示一个正确的虚拟链接。
