The stem flow of spruce and larch had acidulation on the soil, but the soil around the bole of spruce didn't present intensive acidity (the lowest pH of water and KCl immersion were 5.13 and 4.79, respectively), so the acidulation of stem flow is not the direct reason of spruce death.

虽然两树种树干径流对土壤均产生了酸化作用，但由于云杉树干周围土壤PH并没有出现较强的酸性（水浸pH下降到5.13，盐浸pH下降到4.79），因此，还不能认为云杉的衰退死亡与树干径流的酸化作用有直接关系。

Results AQP1 is expressed at the apical and basolateral membrane of the microvascular endothelium; AQP3 was detected at basal cells of both the bronchiole epithelium and submucosal gland acinus; AQP4 is present in the basolateral membrane of columnar cells in bronchiole; while AQP5 is expressed in the apical membrane of type Ⅰ pneumocytes, and also at the apical of columnar cells of superficial epithelium and submucosal gland acinar cells.
