小明模拟大自然“雨”的形成做了如图所示的实验:向锥形瓶中注入少量的温水,稍后,取一干燥的表面皿盖在瓶口,在表面皿中放置一些冰块,稍后在瓶内出现朦胧的“白雾”,表面皿底部看到有小水滴,小水滴逐渐变大,最终下落到瓶内。由此实验可知雨滴形成的过程和物态变化。下列说法正确的是:

[ ]

A.水蒸气上升,当遇冷时,水蒸气凝结成水滴;物态变化为液化

B.水蒸气下降,当遇热时,水蒸气凝结成水滴;物态变化为液化

C.水蒸气上升,当遇冷时,水蒸气凝结成水滴;物态变化为汽化

D.水蒸气下降,当遇热时,水蒸气凝结成水滴;物态变化为液化

某城市热力管道工程,施工单位根据设计单位提供的平面控制网点和城市水准网点按照支线、支干线、主干线的次序进行了施工定线测量后,用皮尺丈量定位固定支架、补偿器、阀门等的位置。
在热力管道实施焊接前,根据焊接工艺试验结果编写了焊接工艺方案,并接该工艺方案实施焊接,在焊接过程中,焊接纵向焊缝的端部采用定位焊,焊接温度在-10℃以下焊接时,先进行预热后焊接,焊缝部位的焊渣在焊缝未完全冷却之前经敲打而除去。在焊接质量检验过程中,发现有不合格的焊接部位,经过三次返修后达到质量要求标准。
问题

热力管道焊接质量的检验次序是怎样的
