But the waterproof is in high to low order as: pentaerythritol phosphate> aminated pentaerythritol phosphate> ammonium monoacid phosphate. 耐水阻燃性作用大小为:磷酸季戊四醇缩合物>磷酸季戊四醇缩合物的铵盐>磷酸氢二铵。
In this paper, the mathematical model of the reltion between water saturation vapor pressure and saturated temperature is established in the form of monoacidic polynomials. 提出了一元多项式形式的水蒸气饱和压力与饱和温度关系的数学模型，进行了牛肉冻结过程的计算机模拟，在此基础上进行了牛肉冻结过程中干耗量的数值计算。
The flame-retardant efficiency of pentaerythritol phosphate,aminated pentaerythritol phosphate and ammonium monoacid phosphate in the liner board was compared. 比较了3种含磷阻燃剂(磷酸季戊四醇缩合物、磷酸季戊四醇缩合物的铵盐、磷酸氢二铵)对箱纸板的阻燃作用。
A series of inhibitors were made from different organic carboxylic acids as monoacid and binary acid to prevent the corrosion of cast aluminum in neutral cooling water. 为了提高中性冷却水系统中铸铝的耐腐蚀性能,通过极化电阻、稳态极化曲线和交流阻抗等电化学方法研究了不同比例一元、二元有机羧酸混合溶液对铸铝的缓蚀性能。
The PH value of a mixed solution of a strong acid solution with a weak monoacid, the two solutions that their PH values and volumes are equal, isn't changed. PH值相等的强酸、一元弱酸溶液等体积混合,只要二者不发生反应,混合溶液的PH值保持不变。
