MS計算孔隙率
|
|
請問有誰用MS 計算孔隙率? 或者可以理解下面文獻內(nèi)容? 求具步驟Sample TextSample Text After creating the zeolite structure, we computed the total accessible volume using the so-called “Connolly surface”[25] , which is the area traced out by the contact surface of the probe molecule as it freely rolls over the framework. This is also known as the solvent accessible area. We use water as the probe molecule, which is assumed to be spherical and to have a vander Waals radius of 1.4˚A. We obtained the occupied volume and free volume of 7275.50 and 3454.98˚A3 , respectively. Sothe total porous volume is 1727.49˚A3/unit cell (0.181 cm3/g), this corresponds to a porosity of 32.2%. This computed porosityis in fair agreement with Fleys’s value of 32%(Analyzing adsorption and diffusion behaviors of ethanol/water through silicalite membranes by molecular simulation Jin Zhi Yang, Qing Lin Liu ∗ , Hai Tao Wang Department of Chemical and Biochemical Engineering, College of Chemistry & Chemical Engineering, Xiamen University, Xiamen 361005, China Received 30 September 2006; received in revised form 4 November 2006; accepted 11 December 2006 Available online 22 December 2006) 我有幾個疑問 1 構(gòu)建模型時,probe molecule H2O要加入體系中嗎? 2 軟件中 TOOL- ATOM VOLUME AND SURFACE--SETUP 中 connolly surface 中的幾個參數(shù) ,grid resolution , grid interval , vdw scale factor ,connolly radius 該如何設(shè)置,有什么講究嗎? |
