给出了两桥链路解链数为1的三个等价条件。作为一个推论，它表明，一个unknotting交叉出现在最小图的两桥结或链接。此外，对于所有未链接的第一个双桥链路，计算组件的链接数的绝对值。
Three conditions equivalent to a two-bridge link having unlinking number one are given. As a corollary it is shown that an unknotting crossing appears in the minimal diagram of a two-bridge knot or link. In addition, the absolute value of the linking number of the components is computed for all unlinking number one two-bridge links.
