Abstract1.根据我们对英仙X的分光光度测量,得到它的星际目视总吸收A_v=1.~m50.把它同3U0352+30X射线观测得到的氢柱密度比较(用经验公式换算到目视总吸收),表明二者离我们的距离大致相同,支持了X Per是3U0352+30的光学对应体的看法.2.同X Per相差22.5角秒处的ADS2859B,星际消光和X Per也基本一致.3.指出ADS 2859B同X Per作为有力学联系的远距双星的存在事实,可能是X射线源3U0352+30起源于一颗大质量星的超新星爆发的证据.联想到离Cyg X-1的9角秒处也有一颗M型星,光度比HD 226868大致弱6~m,因此二者离我们的距离可能也是相同的,也有可能组成一对远距双星,这就更加强我们的看法.
