摘　　要：作者考察了H_(3)BO_(3)-MgSO_(4)-MgCl_(2)-H_(2)O四元体系在273.15±0.05K温度下的溶解度等温线。四元体系共饱和点的液相组成为33.44%(重量)MgCl_(3),1.77%MgSO_(4)和0.65%H_(3)B0_(3)。The quaternary system of H_(3)BO_(3)-MgSO_(4)-MgCl_(2)-H_(2)O has been investigated at 273.15+0.05K by means of the isothermal method.This system is composed of three simple ternary systems:H_(3)BO_(3)-MgCl_(2)-H_(2)O(Ⅰ),H_(3)BO_(3)-MgSO_(4)-H_(2)O(Ⅱ)and MgCl_(3)-MgSO_(4)-H_(2)O(Ⅲ).The solid phases identified are.(Ⅰ)H_(3)BO_(3)+MgCl_(2)·6H_(3)O;(Ⅱ)H_(3)BO_(3)+MgSO_(4)·7H3O and(Ⅲ)MgCl_(2)·6H_(2)O+MgSO_(4)·7H_(3)O.There are three regions of the solid phases:H_(3)BO_(3),MgCl2·6H_(2)O and MgSO_(4)·7H_(2)O in the central projection diagram.The eutectic point is at 33.44 Wt%MgCl_(2),1.77%MgSO_(4) and 0.65%H_(3)BO_(3).
