Porcelain container is not water molecules, and no one correcting the other end of the negative elements, so the electric field of microwave ovens can not make molecular motion, it will not be heated.

瓷容器不是水分子，也没有人纠正的负面因素的另一端，所以微波炉的电场不能分子运动，它不会被加热。

The method for measuring the velocity distribution graph is established when the photosynthate transports along .

把速率范围均匀等分成若干个速率区间，以此为横坐标；测量并计算各速率区间对应运输的同化物或水分的相对百分比 Pi，以此为纵坐标，可得液流中同化物分子和水分子运输的速率分布曲线。

The DFT (B3LYP/6-31 + G) method was used to study the relative stabilities and probable proton transfer in isolated and monohydrated 2,4-dithiothymine molecules in gas phase. The effects of water on relative stabilities and the rate of the proton transfer were analysed. The results indicate that only one tautomer for 2,4-dithiothymine can exist in gas phase.

Via comprehensive computations, the possibilities of vinylidene and allene intermediates were excluded, and the reaction mechanism was found to contain the following three steps:(1) gold-catalyzed cyclization to give the cyclic intermediate,(2) the cyclic intermediate undergoing a 1,3-H migration to give a more stable intermediate, with the assistance of water-cluster,(3) finially, the 1,2-H or 1,2-silyl migration occuring for generation of the observed product.

通过对各种可能的反应路径的进行计算和比较，排除了亚甲基卡宾和连二烯中间体的可能性，并确定该异构化反应机理包含以下三个步骤：（1）炔丙基吡啶反应在金催化条件下发生分子内的成环得到环状中间体；（2）环状中间体在水分子簇的协助下优先发生1，3-氢迁移反应，异构化得到更为稳定的中间体；（3）最后再进行1，2-氢迁移或是1，2-硅烷基团迁移即得到实验中所观察到的环异构化产物。

In the 〓 cluster, the angle formed by the pyridazine plane and the water plane is a main factor that affects the cluster's stableness.

在团簇〓中，哒嗪分子和水分子两平面之间的二面角是影响其稳定性的主要参数。

The copper atom is in a planar coordination site of [N_2O_2] and it devites from the mean plane by only 0.80 pm. Byπ-πstacking interactions, a alabastrine structure was obtained.(2)Schiff-base complex [Cu(H_2O)]·H_2O, where H3GS is the 3-carboxyl -salicylidene glycine, was synthesized and characterized by elemental analysis, IR spectra and single-crystal analysis. The crystal belongs to monoclinic system, space group P2(1)/c, a=848.46(3)pm, b=681.54(3)pm, c=1967.16(8)pm,β=95.8210(10)°, Z=4, R_1=0.0279, wR_2=0.0724.
