中文拼音 [qìshíxiànxiàng]
氣蝕現象
英文
cavitation phenomenon-
In allusion to some types of the functional fibre s performances and characters the paper mainly has this fibres microstructure scanned by electron microscrope. in addition we also discuss their differences of microstructure eroded by the plasm. meanwhile by performing mechanics analysis we get theoretical analysis of their space - conglomerating structure. finally we perform analysis of the ultraviolet radiation and analysis of the caloricr weightlessness. as a result these types of fibre not only keep their own fine traits, but also own good conglomerating structure, crystal limit, calorifics performance and mechanics performance. compared with the ordinary fiber, the neatness of high - contracted polyester fiber increases and it s diameter also increases. there are bubbles in the burning - resisting viscose fiber and it has smooth vertical structure
對應子高收縮的滌綸纖維的平整度有所提高，有較普通纖維變粗的趨勢；在難燃粘膠纖維裏面有氣泡，其具有較明顯的光滑平整縱向結構；滌綸系列棉纖維，在其耐刻蝕方面是比較強的，僅有均勻的小部分刻蝕現象；抗菌衛生級粘膠纖維的刻蝕效果是較差的：難燃的粘膠纖維，刻蝕的效果最好；而抗紫外粘膠纖維刻蝕的效果略有遜色。Fuhong class a inorganic dampproof fireproof board adopt natural minerals, featuring good performance in water, sunshine, acid rain, and frosted condition, its lifespan can last as long as more than 20 years, it keeps room warmer in winter and cooler in summer, damp - resistant, wet - resistant, it is applicable to island climate, and wont generate halogenation like ordinary fireproof board

針對當前黑土利用現狀，本文借鑒眾多學者的研究方法和觀點，在吉林農大黑土區選擇利用方式不同的玉米地、休閑地、果園、草地，在玉米區進行了不同數量的施肥，通過野外試驗，採集一年自然降雨產流及泥沙樣品，同時採集降雨前後的耕層土壤樣品，研究了黑土區地表徑流對氮磷養分特徵及肥力退化的影響，結果表明：土壤侵蝕和氮磷的流失受諸多因素的影響，降雨量、降雨強度是重要因子，而降雨強度是影響農田地表徑流養分流失的最重要的氣象因子，特別是暴雨，暴雨徑流中氮磷濃度較平時高得多；隨作物生長，覆蓋度逐漸增加以及不同利用方式下表現的覆蓋度差異，氮磷流失都表現為顯著的差異。High water saturated vapour pressure leads to the more possible occurrence of cavitation phenomena in water hydraulic pump, and so as in sliding shoes hydraulic supporting without exception
