At the prefecture scale,the relationship became complicated between chemical components and leaf quality,and more chemical components were needed to evaluate leaf quality.For example,significant correlation in Zunyi prefecture was found between smoking total scores and total nitrogen,nitrogen to nicotine ratio and nicotine,and between offensive odor and total nitrogen and chloride.

在地级尺度，烟叶化学成分与品质的关系复杂化，需用较少的化学成分(碳水化合物、含氮化合物)反映烟叶的主要品质特征，并需用更多的化学成分(K2O、P等矿质成分)才能反映烟叶品质的特有差别。

Chemistry material is the matter of chemistry movement , also the matter object of chemistry science research.

摘 要：化学物质是化学运动的物质承担者，也是化学科学研究的物质客体。

The current research begins with the developing research of the teaching skills presented by the initial chemistry teachers(beginning chemistry teachers and quasi teachers ), then on the based of the literature researching, according to the produces of microteaching skills and the characteristic of chemistry discipline combined the new requirements for teaching skills of teacher under the new curriculum ideas.

本研究以新手型化学教师的教学技能发展现状为切入点，在对文献进行梳理的基础上，依据课堂教学环节的一般程序和化学学科的特点、结合新课程理念下对化学教师教学技能提出的新要求，提出了所要研究的具体教学技能。

By using CP-TOSS NMR method to suppress the spinning sidebands, 13C isotropic chemical shift of the above complexes was thus obtained. While in the 2D-PASS NMR spectra, spinning sidebands related to chemical shift anisotropy remain and are well-separated according to their orders. The principal components of the 13C chemical shift tensors were then extracted by fitting the experimental intensities of 13C spinning sidebands with Mathematic programs.

利用边带完全压制的CP-TOSS谱图我们得到了样品中各不等价13C位的各向同性化学位移；利用边带完全分离的2D-PASS谱图(其中包含了各不等价位的化学位移各向异性信息)，并通过Mathematic程序包对2D-PASS谱图中完全分离的旋转边带强度进行拟合，得到了各不等价13C位的化学位移张量的主值分量。
