1、第1步，石英管缩颈
抽真空后开始烧结缩颈，缩颈部位烧至凹陷即可
Step 1: Silica tube necking
Frit the necking after the vacuumizing until the necking part gets sunken
2、第2步，装样装石英柱
将样品装入石英管，将石英柱下滑至缩颈处卡住
Step 2: Silica column sample loading
Put the sample into silica tubes and slide the silica column to the necking
for locking
3、第3步，烧结封管
抽真空充气氛后，烧结石英柱的位置进行真空封管
Step 3: Fritting and sealing
Frit the silica column and conduct tube sealing after the vacuumizing and gas atmosphere filling
4、封管成品
封管完成后可以贴上样品标签以便于区分样品
Sealing and completion
Paste the sample label to identify samples after the completion of tube sealing
