解釋
選擇性溶劑過程-
A new process of extraction distillation with salt was developed for the triple azeotropic system of methyl acetate - ethanol - water and the selective method of the solvent and salt were studied
本文針對乙酸甲酯?乙醇?水三元共沸體系,提出了加鹽萃取精餾的工藝過程,並對鹽的選擇和萃取劑的選擇方法進行了研究。 -
Theoretical analysis and experimental results show that the mentioned methods above can simplify the process condition, improve the etched effect, shorten the etching time and obtain more even etched surface. 2 ) laser - assisted wet sequencially - selective - etching method has been developed this method can be applied when the corrosion solution is mixed solvent
2 )提出了激光化學誘導液相次序選擇腐蝕法該方法適用於腐蝕液為混合溶劑的情況,例如, h2so4 - h2o2對gaas基片進行腐蝕時,先採用h2o2對基片進行氧化腐蝕處理,再利用h2so4進行激光化學腐蝕。
