屈出律是乃蛮部太阳汗之子，他兵败后逃入西辽并篡夺了西辽的 政权。关于屈出律的各方面记载有一定程度不同，需要我们进一步进行对照考 释。首先，屈出律逃入西辽的时间，本文认同1208年而非《蒙古秘史》的1205 年；第二，屈出律政变的时间应在1211年，不是1209和1210等年份，同时 本文认为《辽史》所述“猎场之变”之说法疑似有误；第三，屈出律曾娶直鲁 古之女“浑忽”为妻，对于“浑忽”一词的含义，本文在学界已有的“皇后” 说的基础上提出其他一些可能合理的猜测。对屈出律相关历史事实的考释，对 相关史料的对照研究，有助于我们更加深入、全面和准确的了解西辽末年和大 蒙古国崛起的部分历史细节。

Kuchlug Khan is Naiman Tayangkan’s son, he fled to Qarakhitay and usurp it after defeated by Chingiz Khan. The historic textual differs about Kuchlug, and we need to do textual research. First, as for the time that Kuchlug fled into Qarakhitay, this article holds 1208 instead of 1205 from Mongqolun Tobca’an. Second, Kuchlug couped in 1211, neither 1209 nor 1210, and Liao Shi recorded Hunting Ground Coup’eta wrongly. Third, Kuchlug married Qunqu, who is Zhilugu’s daughter, and Qunqu represents Quncuy instead of Qatun. The textual comparation research helps us understanding Late Qarakhiay and the rise of Yeke Mongol Ulus deeper, more comprehensive and more correct.
