1.能量
表面能单位换算:
1ev = 23.0605 Kcal/mol = 1.602176634e-19 J = 1.602176634e-16 mJ
1ev/A2 = 23.0605 ev/A2 = 16021.76634 mj/m2
1Kcal/mol = 6.947695e-21 J = 6.947695e-18 mJ
1Kcal/mol/A2 = 694.7695 mJ/m2,so 23.061 ev/A2 = 16021.7321 mJ/m2 (因为没有用十分精确的数值来计算,结果有点误差,影响不大)
2.力
3.时间
4.压强
5.密度
6. VDW参数
7.扩散系数单位换算:
1m = 10E10 A;1 m2 = 10E20 A2; 1 s = 10E9 ns = 10E12 ps = 10E15 fs;
1 m2/s = 10E11A2/ns = 10E5 A2/fs
1*10e-10 = 10 A2/ns = 1 * 10 E-5 A2/fs
