Due to its relative high sensitivity to precipitation acidity and environmental humidity, the corrosion rate of zinc at TSP was a little higher than that at GYQ.
而对于锌来说，由于其对降水酸度和环境湿度比较敏感，因此，铁山坪站点的腐蚀速率反而稍微高于城区观音桥站点。
The trend of the wet deposition between 1987 and 2004 in Beijing city was analyzed by using two parameters, e. g. precipitation acidity and wet deposition fluxes.
通过分析降水酸度和沉降量2个酸沉降控制指标，得出北京市近二十年（1987~2004）湿沉降特征变化趋势。
Ion balance study showed that the precipitation acidity was not decided on acid ion concentrations only, but manly decided on basic ion concentrations which neutralized acid ion in Wuhan city proper.
离子平衡分析表明，武汉城区降水的酸度高低，不仅取决于酸性离子浓度，更重要的是取决于对酸性离子起中和作用的碱性离子的浓度。
The acidity of precipitation in equilibrium with atmospheric CO2 and SO2 has been calculated for both clean and polluted areas.
本文计算了降水与大气CO_2和SO_2处于平衡态时，干净地区和污染地区的降水酸度。
No crystallization or precipitation occurred in the product, and the acidity and shelf-life were satisfactory. The drink was featured by dark brown colour, pleasant taste and long after-smell.
实验表明该配方生产的双歧保健醋饮料不会引起结晶、沉淀，也不会影响酸度及保存期，颜色呈深红褐色、质地醇厚、滋味酸甜、气味绵长。
