Methods: The single factor experiments, systematically study the extraction of temperature, pressure extraction, the extraction time, an attachment ratio (Cosolvent velocity: carbon dioxide flow) and samples of the particles Cynomorium rate of flavonoids extracted.

通过单因素实验，比较系统地研究了萃取温度、萃取压力、萃取时间、夹带比（夹带剂流速：二氧化碳流速）及样品颗粒度对锁阳黄酮提取率的影响。

Results showed that extraction abilities depends on the hydrophobic of solutes which pK〓 values are similar, e. g. acetic, propionic, butyric and valeric acids, while pK〓 values affect dominantly the extraction abilities of acids with similar hydrophobic, e. g. formic, acetic, chloroacetic, dichloroacetic, and trichloroacetic acids. Meanwhile, diluents and TOA concentration also affect the extraction equilibria of acids through the specific basicity of TOA .

TOA对酸性差别很小的一元羧酸如乙酸、丙酸、丁酸、戊酸的萃取能力主要取决于羧酸的疏水性参数logP；TOA对疏水性参数差别较小的羧酸如甲酸、乙酸、一氯乙酸、二氯乙酸、三氯乙酸的萃取能力主要取决于羧酸的电性参数；稀释剂的种类、TOA的浓度都会影响TOA的表观碱度pH〓，并通过TOA的表观碱度影响羧酸的萃取平衡。

In order to simply the method, we further propose using magnetic stirring with weighted ring in stead of argon sparging; using air-circulated incubator in stead of water bath for better observation and sample collection; using centrifuging in stead of filtration for extract pretreatment; using one phase of simplified bioaccessibility extraction method instead of the two-phase method for a better estimate to the in-vivo method.

爲进一步简化试验方法，建议将开放式反应槽改为密闭式；使用可调速磁力搅拌及具载重环磁石，取代昂贵之氩气搅拌；将水浴温控改为气控式，以利试验观察与采样。此外，小肠相萃取不使用吸附剂，萃取液前处理利用高速离心取代压阻较高之过滤方式。本研究二阶段试验之生物有效性皆低估动物试验RBF，建议可将二阶段胃肠体外试验方法改为单相一阶段生物有效性萃取(simplified bioaccessibility extraction， SBET)试验方法。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
