The change of a substance from a solid directly to a gas is referred to as {Blank}. The process when a solid changes directly to gas is called [{Blank}]. State the process by which solids change directly to gases and from gases to solids. ...
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 ...
to as “gas-to-wire,” or GTW, technologies); using compressed natural gas (CNG) that avoids the cost of gas liquefaction; converting gas, particularly associated gas, into solids or slurries formed of gas hydrates for storage and transportation (generically referred to as “gas-to-solid,” ...
The gas generated by a solid gas generator serves as primary energy source. For example, gas turbine engine, gas booster accumulator for the Sparrow series; gas turbine driven engine-hydraulic pump for the Aspide. 2. The gas generated by liquid gas generator is used as primary energy source....

whileitimes of specular reflections will lead to an enhancement of 2i + 1 times12. For a certain solid surface that the probability of diffuse reflections isf,itimes of specular reflections occur with a probability off(1 −f)i. Accordingly, Smoluchowski model can be derived and the enh...
and the size of the protrusions ranges from 1.5µm to 6.5µm. The surface of the protrusions is also coated with particles-like nanostructure with the size of a few hundred nanometers (figure3(c)). Such micro/nanoscale hierarchical structures...
Electricity can be used directly as a transportation fuel in battery-powered electric vehicles (EVs); in combination with an onboard engine, electricity can supply the motive power for hybrid electric vehicles (HEVs). Also, electricity can be used to produce H2via electrolysis of water. The ene...
