The effective permeability is stated as some numerical value at some given saturate conditions 有效滲透率用在一定飽和條件下的數(shù)值表示。
Under unsaturated condition , the duration of the transport process was obviously prolonged , peak value of the breakthrough curve raised , the preferential flow was not significant and the curve was gently 在非飽和條件下,硝態(tài)氮運(yùn)移過(guò)程的時(shí)間明顯加長(zhǎng),穿透曲線的峰值增高,優(yōu)先流不明顯,穿透曲線平緩。
The time and the devotion of procreate of three species are both influenced by soil water . it is possible for three year old flourish plant of c . smyrnioide to flowering . it is later more for the plants stressed by drought 3種土壤水分條件下,明黨參和川明參植株一年齡至二年齡的存活率均為85 . 7 ,而峨?yún)⑤^低,飽和條件下最高為71 . 4 ,干旱條件下最低,僅14 . 3 。
The results showed , the breakthrough curve of nitrate vertical transport in saturated condition was more or less non - symmetrical , mainly due to the different proportion of mobile and immobile water in the soil and soil physical properties 結(jié)果表明,在飽和條件下,硝態(tài)氮垂直運(yùn)移過(guò)程的穿透曲線呈現(xiàn)不對(duì)稱形狀和拖尾現(xiàn)象,主要由于土壤中存在著動(dòng)水和不動(dòng)水的比例不同和土壤的物理性質(zhì)所致。
At the same temperature ( 25 ) , soil bulk density ( 1 . 3g / cm3 ) and concentration of applied ions ( 0 . 014g / cm ) , the value of chlorine diffusion coefficient ( dei ) increased linearly with water content , and that of potassium ( dk ) increased exponentially or power - lawly 25c 、非飽和條件下,四種土壤o一、義的擴(kuò)散系數(shù)均隨含水量的增加而增大,前者隨含水量呈線性增加,后者呈指數(shù)函數(shù)增加或冪函數(shù)增加。
