[求助] 请教真空管式炉样品放置问题

通常我们使用真空管式炉(气氛炉)时,先把样品放入管内、抽真空、设定程序升温。在加热过程中无法再放进放入样品或移动样品的位置。最近看一篇文献(Electrochemistry Communications 14 (2012) 39–42)时文中这样叙述:

samples were placed at one-side of the quartz tube. When the center part of this quartz tube was heated to 900 °C under vacuum, the sample holders on the side
were quickly inserted into the tube center preheated at 900 °C and kept at this temperature for 2 h.

不知作者怎么移动加热样品的?请知情者告知,谢谢。
