在临床和药剂工作中,等渗(iso-osmia)和等张(isotonia)是为人熟悉的两个概念。等渗溶液或等张溶液的制备和应用极为普遍。但是,对于这二者的理解和认识并非一致及完善,继续这一方面的理论研究和实验仍有必要。一、等渗和等张的含义与应用如果两种不同浓度的溶液被一理想的半透膜隔开,这种半透膜只透过溶剂而不透过溶质,则出现溶剂从低浓度溶液移动到高浓度溶液中的渗透现象。这种移动溶剂的力就是渗透压。当两种渗透压相同的溶液被
In clinical and pharmacy work, iso-osmia and isotonia are two familiar concepts. Preparation and application of isotonic solution or isotonic solution is extremely common. However, understanding and understanding of the two are not consistent and perfect, and it is still necessary to continue theoretical research and experiments in this respect. First, the meaning and application of isotonic and isotonic If the two different concentrations of the solution is separated by an ideal semi-permeable membrane, the semi-permeable membrane through the solvent and not through the solute, the solvent appears from the low concentration Penetration into a highly concentrated solution. The force of this mobile solvent is the osmotic pressure. When both osmotic pressure of the same solution is
