hydration 中文解釋 wordnet sense Collocation Usage Collins Definition
  1. the process of combining with water; usually reversible
  2. (hydrated) hydrous: containing combined water (especially water of crystallization as in a hydrate)
  3. (Hydrated) Hydrate is a term used in inorganic chemistry and organic chemistry to indicate that a substance contains water. The chemical state of the water varies widely between hydrates, some of which were so labeled before their chemical structure was understood.
  4. (hydrated) Combined chemically with water
  5. (Hydrated) A dry chemical that is combined with water in its crystal structure. Hydrated products are more stable than anhydrous products.
  6. (hydrated) HAVE ENOUGH WATER INSIDE.
  7. (Hydrating) Restoring or maintaining normal proportion of fluid in the body or skin.
  8. (Hydrating) To supply water in order to restore or maintain fluid balance
  9. (Hydrating) adding moisture to the skin.
  10. The chemical combination of water into a substance.
  11. process of take up of water by the fibres through crushing and fibrillation during beating.
  12. The condition of having adequate fluid in the body tissue.
  13. A fluid intake sufficient to yield a daily urinary output of at least two liters in adults and the maintenance of a neutral or, preferably, slightly alkaline urine are desirable.
  14. A chemical reaction, usually in weathering, which adds water or OH to a mineral structure.
  15. The provision or restoration of water to bodily tissue. Death from dehydration is a common killer of children who suffer from severe, prolonged diarrhea.
  16. a process of chemical weathering. Some minerals take up water and form weaker compounds e.g. anhydrite + water = gypsum which more readily dissolves. The expansion can also put physical stress on the rock.
  17. When a molecule has water molecules attached to it.
  18. A term that refers to the capacity of flour to absorb water. Hydration is usually stated as a baker's percent, or ratio, that is equal to the weight of water divided by the weight of flour used in a recipe. ...
  19. In concrete, mortar, grout and plaster, the chemical reaction between hydraulic cement and water in which new compounds with strength-producing properties are formed. The hydration reaction is exothermic, or generates heat. see heat of hydration.
  20. Chemical reaction involving the addition of water. In portland cement, the chemical compound constituents undergo a series of chemical reactions in the presence of water that cause it to harden (or set).
  21. The chemical and/or mechanical treatment of fibers (other than cooking and bleaching) prior to sheet formation. Such treatment increases the ability of the fibers to absorb water and develops the bonding characteristics.
  22. Water molecules are attracted to ions in water solution and coordinate around the ions, forming a sphere of hydration.
  23. The process by which one maintains the correct water ratio in one s body (e.g., by drinking water)
  24. the ratio of liquid ingredients (primarily water) to flour in the dough. A dough with 500g of flour and 340g of water has a hydration of 68% (340/500).
  25. The process of combining quicklime with water to create hydrated lime or calcium hydroxide. CaO + H2O = Ca(OH)2. This process is called 'slaking'. Due to the extremely hydrophilic nature of quicklime hydration is a volatile process which gives off large amounts of heat. ...
