| 8. | In comparison with sol - gel system catalyzed by potassium carbonate and sodium carbonate , the gel time was markedly shortened and the densities of the prepared carbon aerogels were obviously reduced
相对以k _ 2co _ 3和na _ 2co _ 3为催化剂的凝胶体系，凝胶化时间大大缩短，所得气凝胶密度降低。 |
| 9. | Taking the lest total internal losing exergy for target function , the distribute of difference in temperature among the three - effect is also acquired . an experimental device for three - effect falling - film evaporation was designed and constructed . the experiments of potassium carbonate solution was finished under different temperature of vapor and different input material liquid volume
建立了三效降膜蒸发的实验装置，以碳酸钾溶液为原料进行了不同加热蒸汽温度、不同进料量的实验研究，得到了实验设备的(火用)损分布，并研究了各部分损失的(火用)及有效利用的(火用)值与加热生蒸汽温度与进料量的关系。 |
