在冲击靶板上，整个冲击区域呈现出中心温度最低的近似圆形的对称性分布，对流换热系数曲线呈现出中心对称的波峰分布形状，表明自耦合射流驻点区换热最强。

According to calculated results, isoelectronic density graphs of all molecules were plotted, then population analysis were carried out, so the properties of molecules and reaction mechanism were illuminated at microcosmic aspect.

同时得到了各驻点分子的等电子密度三维示意图，进行了布居数分析，从微观上阐明了反应中各分子的性质以及反应的机理。

Furthermore, single-point energy calculations were refined at the QCISD level of theory with the same basis set (6-311++G**). As a result, the singlet reaction of silylene with isothiocyanic acid contain S-atom abstraction channel, N—H inserted channel, and NH abstraction channel, respectively.

又用QCISD/6-311＋＋G**//B3LYP/6-311＋＋G**方法计算了各个驻点的单点能，计算结果表明单重态的硅烯与异硫氰酸的反应有抽提硫、插入、抽提亚氨基的路径。

The flow-field around a hemisphere and a flat-nosed cylinder in the shock tube is simulated numerically by using non-equilibrium Navier-Stokes equations with an air chemical model of 5 species 17 reactions, and the catalytic rate constant of surface materials such as Pt, SIC:, Ni and a flight vehicle materials is determined by using the heat transfer rate of testing in the shock tube and the distribution of heat transfer rate along with the catalytic rate constants.

Her determination to staff more outposts in countries that have little U.S.

她下决心要在目前美国影响力甚微的国家多设几个外交人员常驻点，也令人叫绝。

At the B3PW91/6-31+G level of DFT, the geometries of all species (reactants, transition states, and products) were optimized and the vibration frequencies and zero point vibrational energies were calculated.

在B3PW91/6-31+G水平优化了12个不同反应通道上各驻点(反应物、中间体、过渡态和产物)的几何构型，并计算了它们的振动频率和零点振动能。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
