微酸性

In 2003,on the whole the soils in Wujiang were little acid, pH from 6.40±0.38 to 5.40±0.55now, and the trend of acid was in Tailake region. The available phosphorous in Paddyfield were significantly lower than. the other five land use patterns. As a result,controlling the phosphorous output form vegetable field mulberry yard and other dryland might be more significant to control the non-point pollution in Tailake region.

吴江市土壤基本上属微酸性土壤，2003年耕地监测中土壤pH值由1982年的6.40+0.38变为5.40±0.55，可见近20年来太湖地区普遍存在的酸化趋势；在稻田、林地、桑园、菜地、果园、旱地六种常见的土地利用方式中，稻田土壤速效磷显著低于其它五种利用方式中；因此，在控制太湖地区磷的面源污染上，控制菜地、桑园和其它旱地土壤磷的输出可能更为迫切。

From the perfusion experiments with isolated rabbit heart and vessels were obtained the follow- ing results:(1)Potassium antimony tartrate produced depression of the isolated rabbit heart,and this depressant action became more marked when the pH of the solution was raised from the original value of 5.4 to that of 7.2;(2)At the same pH levels,the cardiac action of the potassium salt was slightly stronger than that of the corresponding sodium salt;(3)The slight vase-dilator effect of potass- ium anti...

从离体器官的灌注实验得到下列结果：(1)酒石酸锑钾对离体兎心有抑制作用，将其pH 从5.4调整到7.2时，作用亦随以增加。(2)在相同 pH 时，酒石酸锑钾的心臓抑制作用较酒石酸锑钠略强。(3)酒石酸锑钾对离体兎耳血管的轻微扩张作用，系由于该药溶液的微酸性反应，当将药液 pH 调整至7后即无作用。(4)对于离体兎肺血管则不问 pH 为4.8或7，均产生轻微的血管收缩作用。
