to a process for the outward transfer of solids from process gases under pressure, followed by conveying the removed solid to a downstream further utilisation, for example combustion, the process being characterised in that outward transfer and conveying of the solid is effected by a process gas....
When a substance changes from a solid to a gas without passing through the liquid state, it is called ___. A. melting B. boiling C. sublimation D. condensation 相关知识点: 试题来源: 解析 C。物质从固态直接变为气态而不经过液态的过程称为升华。选项 A“melting”是熔化;选项 B“boiling...
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 ...
A process for reducing the release of gas from dumped solid refuse comprises injecting into the solid refuse a liquid slurry formed by mixing a solid mixture comprising a) at least one siliceous component which is actually or latently hydraulic, b) at least one alkaline earth component based on...
Phase change from solid to gas is known as ___. What is the phase transition? A) A process that does not involve any energy B) A process that changes the temperature of the system C) A chemical process that changes the chemical nature of the substance D) A ph...
Gas–solid two-phase flow features temporal-spatial multi-scale structures. Calculation of characteristic scales for an air/FCC (fluid-catalytic-cracking particle) flow indicates that the lack of scale separation entails a structure-dependent modeling approach even on the sub-grid level. For solving ...
shown in FigⅠis intended to illustrate the one-step process.图①是说明一步法的流程图。5、增补法 A 增补法表示复数概念词 After a series of experiments important phenomena have been ascertained.B 对表示动作意义的名词进行增补。activation distribution observation preparation resolution C 在英语名词或动...
the other theory is called the disk instability theory.The disk-instability theory holds that gas begins the planet-making process, without a solid core.You see, most of the outer accretion disk would have been gas.We believe solid particles probably made up just one percent of the outer accr...
The United States Green Building Council, a nonprofit industry group that encourages the creation of environmentally conscious buildings, will introduce a bird-safety credit this as part of its environmental certification process。 There are no easy fixes, however. A few researchers are exploring ...
