    2 ）耕作制下紫色土的產流主要機制是： 1 ）當雨前土壤含水量未達到飽和狀態時，表面產流起始時間有明顯滯后現象，這與紫色土的快吸水性和較多非毛管孔隙密切相關；當雨前土壤較乾燥，降雨初期雨強較大時，易形成臨時相對不透水表層，表面產流峰也有明顯滯后現象。 2 ）表面徑流的產流方式主要是超滲產流，當土壤達到飽和狀態后，有四川大學博士學位論文小部分回歸流發生，但主要是飽和超滲產流發生，因為紫色土的相對不透水層和其它透水障礙層不明顯。 3 ）壤中流主要是飽和產流，與降雨過程有明顯的滯后，而且雨停后的壤中流產流歷時與降雨特徵無關。

  5. Recently sanyo, which sold the less than 10, 000 rmb washing drying machine, obtain the market and get the huge profit. but after the flourishing development, the manufacturers should know 2 characteristics : 1 because of the particularity of the products, the enhancement of the market quotient shall not only lay on the price of the products, and the enterprises shall find out the ways those are suitable for themselves to popularize their products. 2 for the lag of the level and intention of the consumption, in short date, it will not change from wave - ring to roller quickly in our country

    但在這種繁榮發展的背後，廠商也應當清醒地認識到市場推廣過程中的兩大誤區：第一由於其產品的特殊性，對於市場份額的提升並不能單純地依託價格手段的拉動，企業必須尋找到合適產品定位的推廣手段和方法，實現漸進式推廣第二由於現階段消費水平和消費觀念較為落後，因此短期內我國洗衣機市場不會迅速實現從波輪機向滾筒機的迅速轉型。
