cavitation phenomenon 中文意思是什麼

cavitation phenomenon 解釋
氣蝕現象
  • cavitation : n. 1. 【航空】氣穴現象；氣渦現象。2. 【物理學】成穴；空化，（超聲波的）空穴作用；【醫學】成洞，成腔。
  • phenomenon : n. 1. （pl. -na ） 【哲學】現象 （opp. noumenon）; 事件。2. （pl. phenomenons） 稀有現象；奇跡；珍奇；珍品；非凡的人。3. 【醫學】癥候。
  1. This is the basis of the phenomenon called cavitation.

    這就是所謂汽蝕現象的根據。
  2. The characteristics of high pressure gyratory sprayed pumping discusses is presented, which is applicable in wide range of scope and ground layers, convenient for construction, long durability, wide source of materials. mechanism for subgrade strengthening : complex foundation of cement solid and earth between piles was formed by pulsant load of flowing pressure and spraying flow, water wallop, cavitation phenomenon, water wedge effect, extrusion force and air flow agitation etc so as to enhance foundation bearing force and reduce settlement and deformation

    高壓旋噴注漿技術具有適用范圍、適用地層較廣，施工方便，耐久性好，材料廣闊等特點；其加固地基機理主要是通過流動壓、噴射流的脈動負荷、水塊的沖擊力、空穴現象、水楔效應、擠壓力、氣流攪動等效應形成水泥固結體與樁間土的復合地基，從而提高地基承載力，減少沉降變形。
  3. Firstly it discusses the value, meaning, background and method of this topic. then it deducts the single - bubble sound pressure, spectrum of sound pressure, power spectrum. according to the real situation of traveling bubble cavitation noise around a schiebe body, the mathematical model of single - bubble collapse is selected, furthermore, the mathematical model of mass traveling bubbles without interference effect is established, and the multi - peaks and rebound phenomenon while bubbles collapse is also analyzed with statistical method

    首先論證了本項研究的意義，價值，背景和方法，然後推出了單空泡輻射噪聲聲壓，聲壓譜和功率譜，針對回轉體流動泡空化噪聲的具體情況，選擇了雙指數模型作為單空泡潰滅的數學模型，進一步建立了無干涉條件下的群泡輻射噪聲的數學模型，並用統計的方法分析了空泡潰滅時的多峰值和反彈現象。
  4. The operation measures for controlling over - filling ( over - emptying ) are feasible ; the hoisting loads of valve and miter gate are less than their design values respectively ; but, there exists cavitation phenomenon needed to pay attention to the first crossover culvert when the value is near and after whole opening

    控制超灌（泄）操作方式可行；閥門、人字門啟閉力均小於設計值；閥門接近全開至全開后，輸水廊道第一分流口有空化現象。
  5. Computer auxiliary study on cavitation and damage in hydraulic valve abstract applicant : li zhibo supervisor : associate professor hu guoqing professor lin qi a phenomenon of cavitation and damage in flow field and the principle of cavitation and damage in hydraulic valve and its influencing factors are studied in the paper

    所以液壓閥內的空蝕空化研究是經濟建設中一個非常重要的課題。本文討論了流場內部的空蝕空化現象的形成機理及影響因素，主要針對液壓閥內空蝕空化現象進行研究。
  6. At same time, author suggests to change cavitation factor to important operation condition during pressure fluctuation test so to avoid producing the phenomenon of cavitation stimulus in the prototype operation

    同時，建議針對水輪機的重要運行工況，增加不同空化系數下的壓力脈動試驗，以避免在真機運行時可能產生「空化自激」現象，確保原型機組的安全運行。
