Hydrogen adsorption of mwnts increased not only after doped in kno3 solution but also with the increase of solution concentration in certain extent Peg是一种长链分子,对于氧化锌的一维生长可以起到诱导作用。
The characteristic absorbances and film thicknesses of the films increased with the number of bilayers and also with the deposition solution concentrations 复合膜的特征吸光度和膜厚度随着双层数的增加而线性增长,而且也随所使用的沉积浓度的增加而增加。
At last , the influences of the rate of energy storage , solution concentration differences and the temperature of cooling water to economic indicators are discussed 另外,本文还详细计算了蓄冷率、溶液浓度差和冷却水温度对潜能储存系统各项经济指标的影响情况。
The relationships between the energy storage density , cop , the rate of crystallization and the solution concentration difference , the temperature of cooling water are also discussed in the paper 此外还分析了系统蓄能密度、 cop及结晶率随溶液浓度差和冷却水温度的变化情况。
The factors , such as feed solution concentration , stirring speed , strip solution concentration and the ph value of feed solution , have been discussed when the membrane phase only contained membrane solvent 当膜相中不含载体时,分别考察了搅拌速度、料液相浓度、反萃取液浓度和料液相ph值等因素对渗透系数的影响。
3 when fnj l is used in solution , if the crystal appears because of low temperature , we should make the crystal dissolving by reducing the solution concentration or heating before using . drying mixing is available to avoid unevenly mixing 本产品是由多种材料复合而成的复合型混凝土外加剂,主要由膨胀减水防冻早强缓凝和阻锈等组份组成。
