gas cushion 中文意思是什麼
gas cushion
解釋
氣墊-
Air is entrained as water jetting into water cushion pool, the gas - liquid two phase flows field are formed. the every phase velocity field are measured by using piv and ptv ( particle tracking velocimetry ) method in the course of jet angle 75and60 in gas - liquid flows of water cushion pool. image house of two phase flows are set up
西安理工大學碩士學位論文使用數字圖像處理技術中的piv和ptv測速技術就射流入水角75度和60度兩種情況分別測量了水墊塘模型水氣兩相流流場的各相速度場，建立了相應的兩相流流態圖像庫。 -
For the tectonic coal ， the properties of higher porosity and lower permeability make it capable of keeping higher gas pressure ； both of the “ isolating action ” and “ gas - cushion action ” cut down the resistance against outburst ； the specifity of high - defomed - extent makes desorption ， escape and flowing quickly become possible ； the existing of weak - seam or “ thoroughfare - seam ” create suitable conditions for the initial erupting and continued developing of coal and gas outburst. on the whole ， it is the synhesis action of all factors ， which leads to outbursts. the existing of tectonic coal with certain thickess is the essential condition of coal and gas outbursts ， but not the sufficient condition
高空隙率、低透氣性使構造煤能夠保持較高的瓦斯壓力；破碎性、 「隔離」作用及「氣墊」作用，使構造煤抵禦外力作用的能力大大降低；構造煤變形幅度大的特性，為瓦斯的迅速解吸、放散和快速流動創造了條件；構造煤薄弱分層或「通道層」的存在，則為煤與瓦斯突出的初始激發和持續發展奠定了基礎；上述因素的共同作用，影響和制約了煤與瓦斯突出的強度和分佈.盡管如此，一定厚度的構造煤的存在只是發生煤與瓦斯突出的必要條件和有利條件，而非充分條件 -
The total force of mobile gas on the chassis of the air cushion has been calculated by gas dynamic methods. it coincided with the actual result
