Porosity increases along with the increasing of coagulation bath temperature, and doesn't have relation to pre-evaporation.
孔隙率随着凝固浴温度的上升而上升，而与预蒸发时间的长短没有关系；
2
The retention rates of Albumin bovine decreases when coagulation bath temperature increases, and first decreases, then increases when pre-evaporation time prolongs.
对牛血清白蛋白的截留率随着凝固浴温度的上升而下降，随着预蒸发时间的延长先略有下降然后上升。
3
The conditions of pre process such as extraction, evaporation, and column separation of sediment samples are optimized.
