释义	cavitation /ˌkavɪˈteɪʃ(ə)n / noun [mass noun] Physics 1The formation of an empty space within a solid object or body.One would expect elevated tritium levels only when deuterons are present and when sound waves produce cavitation, and that's what the Oak Ridge-RPI-RAS group found.... The role of branch junctions as a feature which enhances segmentation could also depend on the vulnerability to cavitation within the junction, but the present authors are unaware of any studies that have investigated this directly. As a result of cavitation and embolism formation, stem hydraulic conductivity is reduced, which may be critical for a plant under drought stress. 1.1The formation of bubbles in a liquid, typically by the movement of a propeller through it.The formation of such a bubble is called cavitation.... In liquid, these high-frequency waves cause the formation of microscopic bubbles, or cavitation. Cavitation manifests itself in at least two modes; stable cavitation (slow, periodic oscillations of gas bubbles) and transient cavitation.
