On the other hand, the synergetic effect could be found during BS-UC adding to mixed alkanes culture. Furthermore, BS-UC could increase the hydrophobicity of cell surface and thus enhanced the ability of cell attachment to alkane. Adding BS-UC also increased the Zeta-potential of cell and medium surfaces significantly, i. e. BS-UC could decreased the negative electric charge density of their surface, so the repulsive tension between cell and medium would be weakened and the adsorption of them would be easier. The results of the test with sand filled column for investigating the cell adsorption in pore-medium showed that the residual amount of cell in the column increased with increase of adding BS-UC concentration.

此外，在以混合烃类为底物时会产生一定的协同促进效应；添加生物表面活性剂BS-UC，可以显著提高细胞表面疏水性，使得其与烃类及其它疏水表面接触能力增强；BS-UC还可以明显提高细胞及介质表面的ζ电位，使所带负电荷密度降低，从而使得两者间斥力减小而便于吸附；通过沙填充柱洗脱实验，对BS-UC增强细胞在填充介质中吸附能力进行了考察发现，随BS-UC浓度的增加，细胞在填充介质中的保留量也随之增加。

As to the higher Landau levels, we conducted systematically calculations for the various possible ground states, such as the Laughlin liquid, the composite fermion liquid, the Wigner crystal, and the charge density wave . We find that when the Landau level index N≥2, the fractional quantum Hall states are ruled out and the CDW and Wigner crystal dominate. An exception occurs at around v=4+1/6, where the composite fermion liquid may be more energetically preferable than the CDW and the Wigner crystal states. This result provides a new explanation to the so-called re-entrant integral quantum Hall effect. In fact, the feature of isotropically metallic property at this filling is discerned from the experiment.

对于高朗道能级，我们对各种可能的基态，比如量子霍耳态，复合费米子流体，Wigner晶体，电荷密度波等，做了系统的计算，我们发现，当朗道能级N≥2时，分数量子霍耳态不再出现，Wigner晶体和电荷密度波将占主导地位，一个例外就是在ν=4+1/6附近，复合费米子流体可能出现在从Wigner晶体到电荷密度波晶体之间，该结果为上述的重进入整数量子霍耳效应现象提出了一种新的解释。
