"Sulfa drug: Common term for sulfonamide drug, any member of a class of synthetic antibacterial drugs with a particular chemical structure including Both sulfur and nitrogen atoms."

磺胺药：任何同时含有硫和氮原子的特殊化学结构的合成抗菌药物。

The influence of end alkoxy group, configuration and complexation of the compound on the liquid crystalline behavior has been invested.

中间体、配体和配合物的化学结构经元素分析、IR、UV-vis、~1H NMR、荧光和原子吸收等方法确证。

A newly developed three-dimensional holographic vector of atomic interaction field（3D-HoVAIF）was used to describe the chemical structure of 200 aromatic compounds with toxic effect on Tetrahymena pyriformis.

采用新型的的三维原子场全息作用矢量（3D-HoVAIF）研究了200种芳香化合物的化学结构与其生物毒性的定量构效关系。

Our model is obviously superior to Rinker'smodel. because Rinker's model potential is a combination of Thomas-Fermi-Dirac potential and Hartree-Fock-Slater potential for the isolated ion.

我们的模型明显优越于Rinker的模型在于： Rinker的模型采用的是Thomas-Fermi-Dirac势和自由原子的Hartree-Fock-Slater势的迭加形式，而我们的模型中除离子的结构因子外，电子散射势、化学势及电离度等量都是通过自洽迭代方法计算的。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
