It was shown that not only pore surface chemistry but also the pore structure of samples activated by air were different from those by traditional steam, carbon dioxide and potassium hydroxide activation.

研究结果表明，所制备的样品不仅具有特殊的表面结构，同时其孔隙结构也与其它方法所制备的ACF有较大差异；样品对低浓度下的极性分子如水蒸气有较好的吸附选择性。

Membrane affinity quantified by IAM and liposome/buffer systems was a more efficient predicator of α values than hydrophobicity from n-octanol/buffer system. Consequently, not only hydrophobic force but also attractive polar extra-interactions involved in the binding to IAM and liposomal membranes but not in an n-octanol phase, ascribed to the binding process within AM. The binding to ordered lipid membrane in the larger part determined drugs'binding to AM intracellular compositions, and the ordered phospholipid plasma membrane was a potential site for drugs'binding in AM.

脂质体／水系统和磷脂膜色谱所测定的膜亲和性比正辛醇／水系统的疏水性更好的预测巨噬细胞内药物的α值，因此包含在磷脂膜色谱中但并不体现在正辛醇／水系统中药物与磷脂膜之间的额外吸引性极性作用力对药物在细胞内结合有着重要贡献；药物与有序磷脂膜的结合在很大程度上决定着药物与巨噬细胞内成分的结合，有序磷脂分子膜可能是巨噬细胞内部潜在的结合部位。

Both the primary coil and secondary coil are encapsulated in the plastic shell by epoxy.

The most critical events appeared to be the establishment of apical-basal patterns of symmetry,formation of apical meristems,and differentiation and axial change of procambium during the development of cotton somatic embryos.

棉花体细胞胚发育过程中最关键的事件似乎是极性的建立、顶端分生组织的形成以及前形成层的分化和生长轴变化。

The fern spore, the original cell of the gametophyte, carries out asymmetrical mitosis to produce a large cell and a small cell. The small cell geminates to a rhizoid by tip growth, and the large cell further divides and develops to become a prothallus.

蕨类植物孢子作为配子体的原始细胞，通过不对称的有丝分裂产生一大一小两个细胞，小细胞萌发出极性生长的假根，大细胞继续分裂发育为原叶体。

The effect of various polar fractions from Psoralea corylifolia L. ethanol extract on cell proliferation and differentiation were further examined and its ethyl acetate fraction were found to be active fraction.

对补骨脂不同极性萃取物进一步进行成骨样细胞增殖和分化活性测试，发现补骨脂乙酸乙酯萃取物为补骨脂中的主要活性部分。

Pore diameter has purificatory function and micro-pores are in favor of increasing content of flavonal glycosides.

本研究结果表明，银杏黄酮普在树脂上的吸附是与树脂的极性、比表面积和孔径密切相关。
