测量并比较了溶解在不同极性液晶溶剂中的不同溶质的有序参数。结果表明，有序参数都可以合理化，并假设存在两种独立的有序机制。用这种方法可以使实验的阶次参数拟合得优于5%。这为准确预测有序液体中的有序参数提供了可能。
The order parameters of a number of different solutes dissolved in a number of different nematic liquid-crystal solvents are measured and compared. It is shown that the order parameters can all be rationalized with the ansatz that there exist two independent ordering mechanisms operating in the liquid crystals employed. With this ansatz it is possible to fit the experimental order parameters to better than 5%. This opens the possibility of the accurate prediction of order parameters in ordered liquids.
