compressible 中文解釋 wordnet sense Collocation Usage Collins Definition
  1. capable of being compressed or made more compact; "compressible packing materials"; "a compressible box"
  2. (compressibility) the property of being able to occupy less space
  3. In thermodynamics and fluid mechanics, compressibility is a measure of the relative volume change of a fluid or solid as a response to a pressure (or mean stress) change.
  4. (Compressibility (computer science)) In algorithmic information theory (a subfield of computer science), the Kolmogorov complexity of an object, such as a piece of text, is a measure of the computational resources needed to specify the object.
  5. (Compressibility) The factor of a gas or a gas mixture that causes it to differ in volume from that of a perfect gas when each is under the same pressure and temperature conditions. Occasionally it is called deviation. It must be determined experimentally.
  6. (Compressibility) A factor expressing the deviation of a gas from the laws of hydraulics.
  7. (Compressibility) The property of exhibiting compression under stress In the case of sheet material, the percent of loss of thickness when subjected to a given load applied by a disc of a given diameter for a specified short time and at a specified temperature as defined according to ASTM F-36 ...
  8. (Compressibility) Property of a soil describing its susceptibility to decrease in volume when subjected to load.
  9. (COMPRESSIBILITY) Minimum length to which one foot of hose can be compressed lengthwise.
  10. (Compressibility) A compound that enhances some property of, or bestows some new property to, the base fluid. In some hydraulic fluid formulations, the additive volume may be as much as 20 percent of the final composition. ...
  11. (Compressibility) All materials are compressible to differing amounts. Highly compressible brake fluids or friction materials require additional input travel and therefore affect pedal feel or response times.
  12. (Compressibility) Forces acting on a rotor blade when its tip speed approaches the speed of sound.
  13. (Compressibility) The relative volume reduction that geological material can undergo when a force is applied or water is removed from the vicinity by pumping.
  14. (Compressibility) USE Mechanical properties
  15. (compressibility) (1) The ability of a powder to be formed into a compact having well-defined contours and structural stability at a given temperature and pressure; a measure of the plasticity of powder particles. (2) A density ratio determined under definite testing conditions. ...
  16. (compressibility) Of water. See under bulk modulus.
  17. A fluid flow is compressible if its density r changes appreciably (typically by a few percent) within the domain of interest. Typically, this will occur when the fluid velocity exceeds Mach 0.3. Hence, low velocity flows (both gas and liquids) behave incompressibly.
  18. capable of being reduced in volume through exertion of external pressure
  19. Excessive decrease in volume of soft soil under load.
