frozen flow 中文意思是什麼
frozen flow
解釋
冰結流-
The phase change of soil moisture and inflation of the frozen moisture c ause the reduction of hydraulic conductivity by reducing the area of flow section and the aperture of soil pore space, increasing the capillary resisting force to soil moisture, and decreasing the water potential gradient because of the increasing of movement distances of soil water
導水率減小是凍結土壤入滲能力減小的根本原因，而土壤中液態水的相變是導水率減小的根源所在。土壤水分的相變及其膨脹通過減小土壤水分過水斷面面積和孔隙孔徑，增大阻力和由於增長運動距離而減小水勢梯度使凍結土壤的導水率降低。 -

本文通過原型觀測、資料分析、理論分析、室內試驗對北引渠道變形的成因和發生機理進行了較為深入的分析研究，給出了造成北引渠道變形的八大原因：流水引起的變形、滲透引起的沖刷、地表徑流引起的沖刷、滑坡變形、乾燥作用、人類和動物活動的影響、風浪引起的沖刷、凍融侵蝕，並著重闡述了凍融侵蝕的機理。 -
In one of the radio phone - in programmes, a caller said the budget proposal he appreciated most was the abolition of estate duty because it would help resolve cash flow problems encountered by small businesses when their assets were frozen during the estate duty assessment period
一位聽眾告訴我，預算案中他最欣賞的就是取消遺產稅的建議，因為這可協助小本經營的市民解?因資產在評核遺產稅期間被凍結，以致資金周轉不靈的困難。 -
In the research, the infiltration characteristics of frozen soils and the characteristics of winter irrigation flow are studied all - sidedly and systematically in order to guide agricultural winter irrigation, but there a lot of work to do on the program for the complexity of the researched problem and the finiteness of research method and means in many aspects the problem has not yet been resolved or the research only stays on a level of qualitative investigation. due to writer ' s poor knowledge, there must be some faults and shortcomings in the paper
本研究以指導農田冬季灌溉為主要出發點，對越冬期間的土壤入滲特性進行了較為全面深入的研究，但由於問題的復雜性和方法手段的有限性，許多方面的問題還未得到解決或者還停留在定性研究的水平上，加之本文作者的能力有限，文中定會存在一些缺點和錯誤，敬請各位學者和專家批評指正。 -
