摘　　要：本文测定了LiCI、NaCl、KCl、KBr、K_2SO_4和Na2SO_4在PEG水溶液中20℃和30℃的粘度B系数,计算出了单个离子的B值。发现Li^+和Na^+起结构促进作用,而其它离子起破坏作用。并讨论了离子-溶剂的相互作用。The viscosity B cocfficents of LiCl,NaCl,KCl,KBr,KI,K_2SO_4 and Na_2SO_4in aqueous PEG solution at zo℃ and 30℃ were measured,the B cocfficents of single ions were caculated.It was found that Li^+ and Na^+ wer structure-maker and others were stucture-breakers.The ion-Solventinteraction was discussed.
