A. evaporation B. condensation C. sublimation D. precipitation 相关知识点: 试题来源: 解析 A。本题考查科学术语。evaporation 是“蒸发”,即从液体变为气体的过程;condensation 是“凝结”,从气体变为液体;sublimation 是“升华”,从固体直接变为气体;precipitation 是“降水”。反馈 收藏 ...
试题来源: 解析 A。解析:蒸发(evaporation)是水从液态变为气态的过程,这符合题目描述。选项B,condensation是气态变为液态的凝结过程,与题目要求不符。选项C,precipitation是降水过程,包括雨、雪等形式,不是液态到气态的转变。选项D,infiltration是入渗过程,指水渗入土壤等,和液态到气态的转变无关。
试题来源: 解析 A。本题考查科学概念的英文表述。“evaporation”意思是蒸发,液体变为气体的过程就是蒸发。B 选项“condensation”是凝结,是气体变为液体的过程。C 选项“precipitation”是降水。D 选项“sublimation”是升华,是固体直接变为气体的过程。反馈 收藏 ...
A. condensation B. evaporation C. precipitation D. sublimation 相关知识点: 试题来源: 解析 B。本题考查水循环的过程。水从液态变为气态的过程叫做蒸发。A选项凝结是气态变为液态;C选项降水是水汽凝结后落下的过程;D选项升华是固态直接变为气态。反馈 收藏 ...
A. change B. changes C. changed D. is changing 相关知识点: 试题来源: 解析 B。一般现在时,主语 it 是第三人称单数,谓语动词用 changes。A 选项 change 是原形;C 选项 changed 是一般过去时;D 选项 is changing 是现在进行时,不符合题意。反馈...

Laminar boundary-layer flows of gas and liquid having a wavy phase-changing interface are analytically investigated to predict the features of their disturbance field. The basic field is approximated to be of linear profiles and perturbed with small wavy disturbances. The rate of phase-change at th...
