When a solid changes directly into a gas, it is called ___. A. evaporation B. condensation C. sublimation D. precipitation 相关知识点: 试题来源: 解析 C。sublimation 是固体直接变为气体的过程;evaporation 是液体变为气体;condensation 是气体变为液体;precipitation 是降水。反馈...
A. Sublimation B. Evaporation C. Condensation D. Distillation 相关知识点: 试题来源: 解析 A。固体直接变为气体的过程称为升华(Sublimation)。“Evaporation”是蒸发,指液体变为气体;“Condensation”是冷凝,气体变为液体;“Distillation”是蒸馏。本题描述的是固体到气体,所以是升华,选 A。反馈 收藏 ...

These techniques allow Feast to exploit a significant share of modern processors' peak performance for FE applications while maintaining numerical efficiency, robustness and flexibility. Last year we reported on our efforts solving Poisson problems with Feast on NEC SX-6 and SX-8, JUMP Juelich and ...
urine sample that contains the drugs of interest. The drugs adsorb onto the surface of the wire. The wire can then be eluted with a solvent or introduced directly into the inlet of a gas chromatograph where the heat will remove the drugs and they will then be swept into the gas ...
