【多选题】输气管中生成水合物的真实情况The real situation of hydrate formation in gas pipeline：（）
A.
气体在管内高速度流动，不可能在某一点生成水合物，而往往在数十米的管段上形成水合物。The gas flows in the tube at a high speed, so it is impossible to form hydrate at a certain point.
B.
形成水合物会改变压降曲线形状。Hydrate formation changes the shape of the pressure drop curve.
C.
生成水合物时伴随有热效应，要放出热量。熔解水合物时，要吸收热量。水合物的熔解热为335KJ/kg，对管线温降曲线有影响。The formation of hydrate is accompanied by a thermal effect, to release heat. When you melt hydrate, you absorb heat. The melting heat of hydrate is 335KJ/kg, which affects the temperature drop curve of pipeline.
D.
此外，还有不少难以考虑周全的因素，如：局部阻力、气流漩涡、结晶中心等，因而有些书上只标明水合物的可能形成区。In addition, there are many difficult to consider factors, such as: local resistance, airflow vortex, crystallization center, and so on, so some books only indicate the possible formation area of hydrate.
