foveolae meaning in English

小凹,小凹的

At the same time , the quality of different - state water was studied . the results show : the soil bulk density of the fir wildwood heightens with the increase of soil depth , specifically 0 . 74 > 0 . 94 andl . 34g / cm3 , the saturated , canaliculus and field moisture contents decrease gradually in layer a , b and c , accordingly the soil total foveola decreases gradually , and the moisture - hold capacity of the soil lessens gradually with the increase of the soil depth ; there is small difference of the soil bulk density between layer a and b in the outer space , which are respectively 0 . 92 and 0 . 99g / cm3 , and the other laws are the same as the in ner in the main ; reverse success often occurs in the low position of the thoroughly - fell trace and plateau marsh is formed
结果表明：冷杉原始森林土壤容重随土层深度的增加而增大，分别为0 . 74 、 0 . 94 、 1 . 34g cm ~ 3 ，饱和持水量、毛管持水量、田间持水量a层、 b层、 c层逐渐减小，十壤总孔隙度也逐渐减小，土壤的持水能力随深度的增加逐渐减弱；林外空地a层、 b层十壤容重相差不人，分别为0 . 92和0 . 99g cm ~ 3 ，其它规律与林内人体相同：皆伐迹地的低洼地段容易发生逆行演替，形成高原沼泽地。
