The infiltration rate in wetting front interface is speeder than that under single trickle source . the wetted soil volume shape becomes a strip which parallel lateral . the soil water content distribution under trickle source wetting front overlapping is more than that of single source 在滴頭流量為5 . 3l h條件下,在相同的入滲時(shí)間內(nèi)大容重土壤的水平入滲距離較低容重的土壤大27 ,而其豎直入滲距離則較小容重土壤小14 。
The movement law that abrasive fluid in centrifugal field is discussed through the analysis of experimental results of high - speed photography , and it is pointed out that in the course of abrasive moving both the moving of layer and the curve changing from front interface to slip are the important factors of influencing processing results 文中通過(guò)對(duì)高速攝影實(shí)驗(yàn)結(jié)果的分析,探討了磨料流在離心場(chǎng)中的運(yùn)動(dòng)規(guī)律,指明磨料流在運(yùn)動(dòng)過(guò)程中,其滑移層的運(yùn)動(dòng)及前沿界面曲線的變化是影響加工效果的重要因素。
