Usually the effect of cavitation appears with a lowered pressure of liquid, for example, in water. However, this effect can be observed and at an elevated pressure. This effect was found by my research supervisor G. Askar'yan 50 years ago. I confirmed it experimentally. Without knowing this effect it is difficult to understand up to the end the cavitation phenomenon. These researches are published.
В реальной жидкости содержатся всегда содержатся зародыши - маленькие парогазовые пузырьки. Если давления понижается, то они растут. Это и есть кавитация. Если в жидкость поместить пузырьки с горючей смесью, то при повышении давления смесь в пузырьках может загореться. пузырьки будут расти.
Но можно ли это явление назвать кавитацией?
Это вопрос терминологии, а не науки.
There is extensive literature on the mathematics and physics of cavitation during the past 50 years.
High speed imaging in the study of acoustic cavitation bubbles is covered in chapter 3 and the relationship between sonochemistry and micropit bubble enhanced cavitation are discussed in chapter 6 in

Dear James F Peters, the answer of this question you could find in Sov. Phys. JETP 01/1990; 70(6):997 - 1002.
Dear James F Peters, and Sergey Sukhinin the answer of this question you could find in Sov. Phys. JETP 01/1990; 70(6):997 - 1002.
Dear James F Peters, and Sergey Sukhinin I'll give the answer with all explanations and drawings after one answer another my question.
Dear colleagues, I would like to ask the Bible question connected with numbers. Can seem that this question is far from interests of pure scientists, but my researches showed that all scientists anyway faced this question therefore I couldn't ignore it. For everything two "bad" numbers are known. The first is "13", the unhappy number or "baker's dozen", and the second is "666", this number of an animal or the devil. From here question: "How in old editions of the book of the Bible pages 13 and 666 were numbered?"
Sincerely yours,
Alexander
Dear Alexander,
A lot depends on which edition of the Bible we consider in terms of page numbering.
For example, the 1611 King James Bible (KJB) had no page numbers. To see how the pages of the 1611 folio edition of the KJB were labelled, see p. 54 in

The first English folio edition of the Bible had 1464 pages, so the issue of the 666th page is not considered.
