用最大气泡压力法,采用三因子一次回归正交设计,研究了Na_3AlF_6-LiF-RE_2O_3体系的表面张力,得出表面张力(Y)与RE_2O_3含量(c_1)、LiF含量(c_2)及溶体温度(t)的回归方程如下:Y=260.78+4.088c_1+0.073c_2+0.557c_1c_2-0.136t-0.00483c_1t-0.00050c_2t。
The maximum surface pressure (Y) and RE_2O_3 content (c_1), LiF content (c_2) and the temperature of the solution (C 2) were obtained by using the maximum bubble pressure method and the three-factor one-time regression orthogonal design to study the surface tension of Na_3AlF_6-LiF-RE_2O_3 system The regression equation of t) is as follows: Y = 260.78 + 4.088c_1 + 0.073c_2 + 0.557c_1c_2-0.136t-0.00483c_1t-0.00050c_2t.
