Definition of substrate in English:

substrate

noun ˈsʌbstreɪtˈsəbˌstrāt

1An underlying substance or layer.
Example sentencesExamples
- In these circumstances, erosion of the substrate leads to stripping of laminae and the generation of discontinuities within the tidal mouthbar unit.
- Cameron found Vermiforichnus clarkei in many substrates from Ordovician to Holocene ages.
- Also, special designs of roadbed through wetlands in permafrost terrain are required to protect the thermal regime in the underlying substrates.
- Where volcanic material has been extruded on to a soft substrate, the rate of erosion of the substrate can exceed that of the lava flow.
- The rhyolites and other large-scale blocks of gabbro and schist are interpreted as large landslides from the Caledonian nappes forming the depositional substrate and faulted margins of these basins.
1. 1.1 The surface or material on or from which an organism lives, grows, or obtains its nourishment.
  底土（层）；培养基；基质；基层
  brachiopods attached to the substrate by a stalk
  Example sentencesExamples
  We describe a simple procedure to allow the broad nature of the organic substrates used for planktonic bacterial growth to be determined.
  The premature growth arrest of breast and skin epithelial cells grown on plastic substrates may be due to an inadequate culture environment.
  Many modern basal angiosperms grow on erosional substrates that are unlikely to be preserved in the sedimentological record.
  In the first type, plants grow on a soil substrate that has a relatively high chance of being covered with leaf litter.
  A lichen may absorb certain mineral nutrients from any of these substrates on which it grows, but is generally self-reliant in feeding itself through photosynthesis in the algal cells.
2. 1.2 The substance on which an enzyme acts.
  底物，酶作用物
  Example sentencesExamples
  Additionally, it has also been suggested that polygalacturonase action on the pectin network may enhance the action of other cell wall-degrading enzymes by increasing the accessibility of such enzymes to their substrates.
  Another approach would be to increase the cellular level of enzyme substrates such as ascorbic acid (vitamin C).
  Paired with a matching substrate, an enzyme speeds up a vital chemical reaction.
  Type O is a nonfunctional allele, because it does not recognize the enzyme substrate.
  Enzymes that act on substrates such as polypeptides, nucleic acids, oligosaccharides, or lipid membranes often interact with more than one substrate molecule.
3. 1.3 A material which provides the surface on which something is deposited or inscribed, for example the silicon wafer used to manufacture integrated circuits.
  （供放置或刻的）底面
  optical disk substrates
  Example sentencesExamples
  A liquid-crystal panel comprises a pair of transparent glass substrates each being provided with an electrode.
  A trench is etched in a surface of the integrated circuit substrate such that a tip is formed.
  Fewer loosely bonded fluorine atoms in the seasoning film results in fewer contaminants being incorporated into films deposited over substrates in subsequent processing steps.
  A flat organic insulating layer is formed on a substrate provided with thin film transistors by coating and baking.
  Only on very smooth substrates like polished silicon wafers, can the thickness of deposited wax layers be measured exactly.
