用连续滴定量热法测定了四元体系Li_2B_4O_7—Li_2SO_4—LiCl—H_2O及其次级体系Li_2B_4O_7—Li_2SO_4—H_2O和Li_2B_4O_7—LiCl—H_2O 298.15K时的稀释热,并结合Debye-Hückel热焓极限公式研究了该体系的平均表观摩尔热焓。
Dilution heat of tetragonal system Li_2B_4O_7-Li_2SO_4-LiCl-H_2O and its secondary system Li_2B_4O_7-Li_2SO_4-H_2O and Li_2B_4O_7-LiCl-H_2O 298.15K were determined by continuous titration calorimetry. The heat of enthalpies of Debye-Hückel The average apparent molar enthalpy of the system.
