When soil antecedent condition is dry and the initial rainfall intensity is high, peak surface runoff also considerably lag behind that of rainfall, because of the formation of temporary relative impermeable top layer ; b ) surface runoff is controlled primarily by infiltration - excess runoff mechanism under unsaturated condition ; the major fraction of surface runoff are dominated by saturated infiltration - excess runoff response, only a small fraction by return flow mechanism when soil is saturated ; c ) subsurface flow is dominated by saturated runoff mechanism, and the duration of subsurface post the rainfall end is dependent upon rather the soil properties than the rainfall characteristics ; d ) subsurface flow intensity in cultivated soil layer ( 0 ~ 20cm ) is high up to 35mm / h when rainfall intensity is up to 120mm / h, indicating the existing of macropores and pipe flow in cultivated layer
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。

During wet weather, the flows in the communal drainage system will increase substantially, thereby dispersing and diluting any wastewater therein. after the wastewater has been discharged into the sea, most viruses in the seawater will eventually be killed by the ultraviolet radiation of sunlight and therefore public health should not be affected
在
雨天時,由於排水渠的水流量增加,渠內的污水會被收集到的

紫外線照射一般便會逐漸死亡,所以不會影響公眾健康。
She went upstairs to her bedroom. there she heard the loudspeaker begin to bellow, in an idiotically velveteen - genteel sort of voice, something about a series of street - cries, the very cream of genteel affectation imitating old criers. she pulled on her old violet coloured mackintosh, and slipped out of the house at the side door
她聽見了他的聲音里,含著一種滿足的異的音調,她到樓上寢室里去,在那兒,她聽見放音礬在呼號著一種矯揉造作的嬌媚蠢笨的聲音,這象是一種布廛的囂喧,象是一個人摹舍己為人一個老販的令人嘔吐的聲音,她穿上了她的

In fact, it can be used without painting the bare metal because it does not rust or corrode like steel frames or aluminum exposed to rock salt. this means you never have to worry about your titanium frame falling apart due to exposure to the weather. the ti 3 - 2. 5 tubing is the high strength material used in the most advanced aerospace applications
鈦合金具有極好的抗腐蝕性能,事實上,作為自行車架的使用,它的表面不需要塗漆保護,因為它不會象鐵和鋁車架那樣生銹或腐蝕,並耐酸
雨紫外線潮濕等的侵蝕,所以你不必擔心其金屬表面會因裸露在空氣中形成凹陷銹蝕。

Although it isn t bad to draw inspiration from the others, it is also very important that the filmmaker should be able to transcend and incorporate the materials into his movie, but obviously, the excessively fruitful plot is little beyond the control of new director sam leung s ability
