Through repairing the fixed bed calandria reactor during the molten salt leakage test in 2×104 t/a cis-butenedioic anhydride unit in Lanzhou Petroleum and Chemical Corporation,a pack of reasonable,practical and feasible technologic means was found to confirm the leakage points caused by molten salt and to repair it in reactor.

通过对兰州石油化工公司2×104t/a顺酐装置中的固定床列管式反应器熔盐渗漏的返修，摸索出一套实用、合理可行的熔盐渗漏漏点确认以及返修的工艺方法，可为类似反应器的制造提供一定的借鉴。

The first special techniques was the method of tightening slip knot predisposed on atrial septal via veins. The suture with loop was placed on the atrial septum incision which will be closed during the decannulation. The loop was hitched up by the drawn-string via vein and tied with two or three slip knot after inserting left atrial cannulas.

第一种特殊技术是一种经静脉应用心导管将右房内预置的滑结拉紧的方法，其要点是术中在要闭合的房间隔切口处做缝合并留好线套，穿上牵引线经左锁骨下静脉引出，插左房管后打2或3个滑结，拔管后应用这种特殊技术将滑结拉紧，并拆除牵引线。
