光谱分析法

The method is terser and more effective than other traditional methods. It proved that wavelet analysis is a more perfect method of spectral feature extraction.

光谱微分法是一种比较成熟的光谱分析方法，它可用来减弱信号中大气散射和吸收对目标光谱特征的影响，但它对噪音

The paper introduces the application of infrared spectroscopy in the process of testing fire-retardant materials.

介绍了红外光谱法在表征阻燃材料与防火涂料结构及研究其阻燃性能方面的应用，讨论了红外光谱分析技术在材料阻燃分析中的应用前景。

The different part of corn seed was examined by Raman and IR spectra.

采用傅立叶红外光谱法及拉曼光谱分析了玉米种子不同部位的成分。

SF and collagen films were treated by negative corona discharge, homothermal surface potential decay was tested to detect the charge stability. Result showed circums- tance humidity influenced severely the surface charge stability. There were polar groups on the surface after corona discharge, and hydrogen bonds existed between these groups. On the other hand, ATR-FTIR analysis indicated the conformation transition of SF was induced by strong electric field and a part of random coil conformation was converted into β-sheet structure.

采用自制的负电晕极化装置对丝素、胶原膜进行了表面处理，等温表面电位衰减法测试材料在不同环境中表面电位的变化，发现环境湿度对材料表面电荷稳定性的影响较大；XPS光谱分析表明材料表面有极性基团产生，这些基团之间有可能会形成氢键，同时ATR-FTIR分析表明丝素的构象在强电场的作用下发生了变化，由无规线团转变为β折叠结构。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。
