The equilibrium geometry,force constants and vibronic frequencies of the SiO2 molecule with linear structure have been optimized by using the Gaussian03 with B3P86/cc-PVTZ; The total internal partition sums were calculated for silicon dioxide with the product approximation. For rotational partition sums Qrot, the centrifugal distortion corrections are under consideration.

应用Gaussian03程序，在B3P86/cc-PVTZ水平上，对二氧化硅分子线性结构进行优化计算，得出其平衡几何构型、力常数和谐振频率等性质参数；采用乘积近似法构建模型计算了二氧化硅分子从20-6000K的总配分函数，其中转动配分函数考虑了离心扭曲修正，振动配分函数采用谐振子近似。

The results indicated that immobilized E2 protein remarkably raises the level of phosphorate-tyrosine in Raji cells , but the soluble E2 protein hasn't obvious impact to phosphorylation of tyrosine of Raji cell. It was presumed that immobilized E2 protein was resembled to natural viron enveloped E2 protein and may more efficiently interact with CD81 molecule.

这可能是因为固相化的E2蛋白类似天然的病毒颗粒，在构象上要更接近于天然的病毒颗粒表面E2蛋白，而且固相化后的E2蛋白在单位体积的密度要高于可溶性的E2蛋白单位体积的密度，使其能够更充分的与细胞表面的CD81分子相互接触作用。

The active conformation of protoporphyrinogen IX (substrate of protoporphyrinogen oxidase) has been established using the Distance Comparisons method. In this paper, four different conformational molecules of Protogen IX and crystal molecule of diphenylethers are analyzed by comparing their geometry parameters. The results show the lower energy active conformation from the DISCO model is more reasonable.
