We also investigated the effect of mechanical force on the rate constant of 〓 permeability .

引起阳离子通透提高的影响因子是膜张力而不是膜的变形性。

Results show that treating the pear juice with FPC-21 resin can reduced pH value, formol index and browning index. Reduction of pH value enhence the decolor ability of XAD-16 resin on pear juice. Reduction of pH value and formol index can control the browning rate of PJC during storage.

结果显示，阳离子树脂处理可降低酥梨汁的pH值、氨基态氮和褐变指数；降低pH值可提高吸附树脂对酥梨汁的脱色能力；降低pH值、氨基态氮可控制70 °Brix浓缩酥梨汁贮存中褐变速度。

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.
