And we have got the following result : 1. the technique of storing water in soil in gneiss area of tai - hang mountain : the more water in soil before rain is, the less water capability of soil is, the time shorter of water flowing from soil is, the easier the water flows on the ground ; the soil capability of reserving water of different soil thickness is terrace > acacia land > pine land > grass land, so the soil is more thick, the soil capacity which contains water is more large ; the accumulated water that flows on the ground is remarkable related with the logarithms of rain time
太行山片麻巖區土壤蓄水規律:雨前土壤含水量越高,土壤可蓄水量越小,出流所需時間越短,容易形成地表徑流;不同土層厚度的土壤蓄水量為:梯田刺槐林地油松林地草地;累積地表徑流量與降雨時間的對數呈顯著正相關,擬合方程為w = a + blnt ,相關系數均大於0 . 92 ,即在降雨強度一定的前提下,降雨時間越長,累計地表徑流量越多。To fulfill the requirement and characteristics of this track, which include paragraph - based and a relevant document supplied by user before retrieval, the rocchio model and vector model are merged to compute relevance between query and document. then, gradient decrease method is used to train the parameters of rocchio model. then, based on the paragraph - level relevance, the sorted documents are returned
