After mainenervations being drawn out and being dried for 4 hours at 60℃,1156 samples of tobacco leaves from different tobacco producing-area were made into powder (≤0.13 mm). Reducing sugar, total sugar, nicotine, nitrogen, potassium and chlorine of more than 1000 samples from different tobacco producing-area were determined with classical chemical or instrumental methods. By scanning these samples with Fourier transform Near Infrared spectrometer (MARIXT-I produced by Bucker) we obtained their spectrograms, pretreated the spectrograms with a chemometrics software (OPUS 5.5) to debase the noises influence on spectrum information, and built a chemometrics model by means of Partial Least2Squares. The chemometric model was optimized some times and validated with some other samples.

选取全国不同烟草生产地区的1156余烟叶样品，采用相同的预处理条件(去处主脉，60℃烘干4小时)，处理成40目待测粉末样品，采用行业经典的化学分析方法或准确可靠仪器方法测定其常规成分含量，在条件一致(20℃～24℃，环境湿度≤40 RH%)的实验室环境中，使用市场上主流的傅立叶变换红外光谱仪(德国BRUKER公司生产的MARIXT-I)上进行图谱扫描，采用OPUS5.5化学计量学软件，对光谱进行适当的预处理，减弱以至于消除各种噪声对光谱信息的影响，用偏最小二乘回归法建立常规成分预测模型，并进行了反复优化和未知样品模型外验证。

When compared with the cellulose acetate butyrate sensor,however,the temperature dependence of PMMA is less.

Platinum and rhodium catalyst are applied largely and widely, because these two kinds of catalysts are so efficient for hydrosilylation that they were researched since a long time ago. Very recently, N-heterocyclic carbene Pt and N-heterocyclic carbene Rh complexes were used as catalysts in hydrosilylation.

最近，铂和铑的卡宾金属配合物作为催化剂应用于各种不饱和化合物的硅氢加成反应，表现出非常优良的催化性能和稳定的物理化学性质，受到了化学工作者们广泛的关注。

Reducing afterblowing and using the carburant with low nitrogen content are important measure. The kinetics of nitrogen removal from liquid steel under vacuum with reaction between carbon and oxygen was studied on the multi-function induction furnace. The following conclusions were obtained by experiments: The nitrogen removal was obtained by the nitrogen transfer through the liquid steel diffusion layer at 67Pa and 110Pa pressure, and by the gas-liquid surface chemical reaction at 2000P.

结果表明：真空度对脱氮机理有影响，67Pa～110Pa时脱氮为一级反应，2000Pa时脱氮为二级反应，1340Pa时为混合控制；即使在。1％的条件下，碳氧反应亦可显著提高脱氮速度常数促进深脱氮，在RH内通过加强碳氧反应来提高脱氮率理论上是可行的；当钢液内存在内生或外来固态粒子时，有利于钢液中CO及N〓气泡的形成及排除，这时气泡内p〓≈0，有可能使钢液中氮含量低干与系统真空度平衡的氮含量。
