振動分害 的英文怎麼說
中文拼音 [zhèndòngfēnhài]
振動分害
英文
vibration hazard for citizen-
Our intelligence is not high enough to disconnect these controlling programmes ? iq 100, which is not enough ( saurians are far from being stupid, their iq is 200, despite this they are bad ), but we can make it by increasing of love for ourselves, which means vibrations of our own bodies
我們的智力沒有高到可以分離這些控製程序?智商100 ，準備不夠充分（蜥蜴人是遠非的愚蠢，他們的智商是200 ，不論他們是有害的） ，但是我們能做到用提高我們的愛來好轉，意味著提高我們自己身體的振動。On the basis of analyzing the working circumstance and prosperity of downhole drilling string of the surface dynamic rotating drilling vertical well, the force prosperity and failure forms of downhole drilling string are focused on. and further research has been done on the vibration damage of downhole drilling string as well as the construction and work prosperity of vibrating - proof hydraulic shocker absorber
本文在對地面動力旋轉鉆井直井井下鉆柱的工作環境和特性加以分析的基礎上，著重對鉆柱在井下的受力特性以及損壞形式進行了分析，並對鉆柱在井下的振動危害以及用於防止振動的水力加壓減震器的結構、工作特性等一些規律進行了深入的探索和研究。Chapter three discusses the vibration forms of the surface dynamic rotating drilling downhole drilling string, analyzes the damage of low frequency ancf fongif ucfi ' na / vibration to downhole drilling string, and set up a set of math models of the longitudinal and torsional vibration
第三章分析探討了地面動力旋轉鉆井井下鉆柱的的振動形式，並提出分析了低頻縱振現象對井下鉆柱的損害，以及建立了縱向、扭轉振動的數學模型。Unsteady separated flow, produced during the gate - opening period in the reverse radial gate tunnel of a high - lift shiplock, is characterized by negative pressure and high velocity as well as their intense fluctuations in space and time and could easily result in various harmful phenomena such as cavitation, gate vibration and sonic boom, which have been observed and confirmed by prototype and physical model tests
高水頭船閘輸水反弧閥門開啟過程中，后廊道內發生急變分離流，負壓、高速水流以及壓力與流速的劇烈時空脈動變化容易誘發空化空蝕、門振和聲震等有害現象已被原型觀測和物理模型試驗研究證實。Because these harmful phenomena are closely related to the dynamic process of the flow, it is of great importance, theoretically and practically to the engineering design, to study the flow regime and predict the variations of flow velocity and pressure so that the hydrodynamic mechanism of cavitation and gate vibration could be analysed
由於這類有害現象的發生與水流的流動特性密切相關，探明閥門段水流急變分離的流態、預測流速、壓力時空變化規律，分析空化與振動的水動力學成因，在理論上和工程設計實踐上皆具有重要意義。How to reduce vibrations of the mechanism systems simply and reliably and how to improve precision and fatigue life time of the machine are important in theory and practice of mechanical engineering, so dynamic models and analysis methods of elastic mechanism systems considering damping effects are necessary
如何簡單可靠地消除和抑制機械繫統的有害振動，提高其精度和壽命是機械科學領域一個重要的理論和實踐問題，因此考慮阻尼的彈性連桿機構建模理論與分析方法是目前一個需要迫切研究的領域。Whole - body vibration - guidelines for vibration hazards reduction - part 2 : management measures at the workplace cen tr 15172 - 2 : 2005
