The factors relevant to the running buffer and their effects on separation were investigated. The buffer solution composed of 30 mmol/L sodium borate and 2.4 mmol/L β-CD was found to be the most suitable electrolyte for separation. The second order dissociation constant range of honokiol was estimated. The content range of honokiol in Cortex Magnoliae Officinalis and was 3.42-5.98 mg/g, while the mean content of honokiol in its preparation 0.021 mg/mL.

Without such detailed information, raking comes as a rescue since it requires only the knowledge of marginal distributions of selected variables. Popular as it may be, raking takes no account of associations among post-stratifying variables. Furthermore, it relies heavily on Chi-squared tests and a pre-selected p-value (usually 0.5) as the stopping rule of iteration, an ad hoc rule justified only by convenience.
因此,目前最常采用的是「反覆多重加权」的方式,但「反覆多重加权」实际执行时,最大的问题在於其检定方式是透过卡方检定,通常只要其检定P值大於0.5,就认定样本与母群一致,而未考虑一个最佳化的加权值。

This thesis analyzes the types and art trait of solar-assisted heat pump water heater, the development trend of direct expansion solar-assisted heat pump water heater, makes a summary of these research results from six aspects. On the basis of these works and from the point of view of receiving optimum solar radiation , the thesis develops a novel design model of direct expansion solar-assisted heat pump water heater with a truncated cone collector/evaporator, theoretically analyzes the heat that the system can absorb, compares its ability with other two types of cylinder and flat plate ones, and calculates COP and EER with computer aids. The results show that a truncated cone direct expansion solar-assisted heat pump water heater can absorb not only more solar energy but heat energy in air. It takes on favorable thermal performance. Under the average day in February which is of the worst weather throughout the year in Kunming, the COP is about 4. 2, EER is about 2.9 . The heat absorbed by the system are more than those of the other systems. The system is very great in terms of saving
