英语翻译
Thermochromatography involves passing a gas through a column whose temperature decreases continuously with distance from the entrance.Thus,the less volatile species condense on the column walls first with the more volatile species depositing last

答案

电色谱法是气体穿过毛细管,毛细管的温度随进口距离持续降低.因此,不易挥发的物质在管壁上先冷凝,易挥发物质后冷凝
做的是化工里的毛细管实验么.
