Structures of Na~+-AD ion-complexes with 1 or 2 H2O molecules were obtained. It was found that H2O can bond with Na~+ in the structure of Na~+-AD to form Na-O van der Waals bond. H2O molecule can also bond with N or O atoms in AD moiety to form H-bonds as N-H…Ow or O…Hw-Ow. The former process takes place more easily. The most stable structures of Na~+-AD ion-complexes with 1 and 2 H2O molecules are W-C7AB and 2W-C7AB, respectively.αB conformer of Na~+-AD can not exist in the presence of 2 H2O molecules.

研究发现水分子可以结合在Na~+-AD络合离子中的Na~+附近形成Na-OW范德华键，也可以与Na~+-AD络合离子骨架结构中电负性较强的N或O原子结合形成N-H…OW或O…HW-OW氢键，相对而言，水分子更容易结合在Na~+-AD络合离子中的Na~+位置，Na~+-AD最稳定的带1个或2个水分子的结构分别为W-C7AB和2W-C7AB，Na~+-AD络合离子的αB构象在2分子水存在的情况下完全消失。

In addition, the energy of s and p orbits of F2 or F3 ion is lower in the ferroelectric phase than in the cented symmetry phase and the covalence character of F1 ion whose contribution to the displacement is largest almost lose, which stabilize the structure of the ferroelectric system.

铁电相F2(F3)离子的能量低于中心对称相，最大位移贡献者F1的化学键性由弱共价作用到离子键的变化也是最大的，这均有利于体系的稳定。

We stopped by the old fashion ice cream parlor Manhattan Beach Creamery for some refreshment. The "No Shoes, No Shirt, No Problem" sign on the wall epitomizes the beach lifestyle.

我们去商店区的一家老式冰淇淋店坐坐，墙上挂著「没鞋，没上衣，没问题」的牌子完全捕捉了海滩生活的随性及风格。

"If therefore", argues Bellarmine we can offer our prayers and our satisfactions in behalf of those detained in purgatory, because we are members of the great body of Christ, why may not the Vicar of Christ apply to the same souls the superabundant satisfaction of Christ and his saints--of which he is the dispenser?

" "因此，如果"，认为贝拉明（德indulgentiis ，十四）"我们可以提供我们的祈祷和我们满意的代表那些被拘留在炼狱，因为我们是成员的伟大基督的奥体，为什麼可能不是牧师基督适用於同样的灵魂满意的过剩是耶稣和他的圣人-他是在配药？
