On the basis of analytical orbit theory, the state transition matrix from mean to transient orbit errors was put forward.

在解析轨道理论基础上，给出了平均轨道要素偏差到瞬时轨道要素偏差的状态转移矩阵。

Based on the pseudobinary method and solute aggregation model of aqueous solution, a pseudobinary solute aggregation model for correlating the viscosity of water-organic solvent-salt solution is established. The model has been tested for ternary aqueous solutions saturated or unsaturated with salt. The average relative deviation is about 1.0%. The results are better than the pseudobinary local composition model presented early by authors.

结合水溶液粘度的溶质聚集模型和拟二元方法，作者提出了一个适用于水-有机溶剂-盐三元溶液粘度关联的拟二元溶质聚集模型，能够成功地应用于以盐饱和与不饱和水溶液粘度的关联，平均相对偏差约1.0%，比作者早先提出的拟二元局部组成模型(平均相对偏差为2～5%)有较大的改善。
