本文研究了与双桥链路相关的链路的H(2)-解结数。它由三部分组成。在第一部分中，我们考虑了二桥连杆具有H(2)-解结数为1的充分必要条件。第二部分关注与H(2)-解结1的复合链接的显式形式。在最后一部分中，我们提出了一种利用二桥结来研究一类结解的H(2)-解结数的方法。
This paper concerns the H(2)-unknotting numbers of links related to 2-bridge links. It consists of three parts. In the first part, we consider a necessary and sufficient condition for a 2-bridge link to have H(2)-unknotting number one. The second part concerns an explicit form of composite links with H(2)-unknotting number one. In the last part, we develop a method of studying the H(2)-unknotting numbers of some tangle unknotting number one knots via 2-bridge knots.
