文章探讨了高分辨傅里叶变换光谱方法研究气体样品吸收线型的基本原理，并通过实验测量以及程序拟合谱线线型，得到了磷烷分子在1950~2480cm-1波段的5个吸收带以及3280~3580cm-1波段的4个吸收带中的1760条谱线线强度，经分析其结果误差在±6%左右。

Therefore, the energy of π(superscript *) orbit decreases, the probability of optical absorption increases, the n→π(superscript *) electronic transition enhances, and the absorption band broadens and shows red-shift. The above phenomenon will result in the degradation of optical properties of ZnO/silicone white paint under proton exposure.

同时Si-O-Si链内氧原子未成键的孤对电子与邻近硅原子的3d空轨道配位，降低了π轨道的能量，提高了对光吸收的几率，增强了n→π电子跃迁，使吸收带红移，从而导致ZnO/silicone白漆光学性能退化。

摘要根据微穿孔板吸声理论，采用理论分析和仿真的方法，着重讨论微穿孔板在温度梯度下的声阻抗、共振频率和吸声系数等声学特性，分析其受温度影响变化的机理。

The modification occurred in crystal lattice and the restoration effect of annealing are discussed by analyzing the intensity, width and angle of the X-ray diffraction peaks. The H〓 concentration and related structural information are deduced by the evolution of OH〓 absorption spectra with annealing, which offers the experimental proof for further discussion on annealing. The disappearance of the OH〓 absorption peak at 3300cm〓 after annealing indicates that some H〓 of high concentration diffused further into the substrate and the crystal phase changes accordingly.

根据质子交换波导退火前后在OH〓吸收峰特征的变化，推断波导层H〓浓度及相关的结构信息，并对进一步分析退火机制提供了实验依据；由于3300cm〓〓处的吸收峰代表的是立方钙钛矿的HNbO〓结构成分，因此退火后该峰的消失确实说明高浓度区域的H〓继续向波导深度迁移的事实，同时波导区的晶相成分也发生变化。

The interaction ways between Tb3＋and horse radish peroxidase were investigated for the first time using UV-Vis absorption spectroscopy, fluorescence spectroscopy, atomic absorption spectroscopy and enzyme separation technique.

考察了大鼠在体结肠对胸腺肽α1(1)及其在各吸收促进剂或酶抑制剂(去氧胆酸钠、卡波姆940、水溶性壳聚糖和杆菌肽)作用下的吸收情况。

Aim To study the absorption characteristics of berberine and its influence on glucose absorption.

目的 研究小檗碱的吸收特性和对肠道葡萄糖吸收的影响，探索小檗碱抗糖尿病作用机制。

Because the fish drying Shrinkage small Shrinkage crack surfaces, more in Water, so the bibulous rate of early (see figure 4) soon, absorbing ability, 1.2 m in bibulous rate (Water absorption Measurement can reach 1 36), In the early EHD water are slower, bibulous rate in 30 m in later, when the water absorption speed enough time to also can achieve higher bibulous rate and natural drying EHD with dry bibulous rate basic same, in addition, natural drying and EHD dry fish good water resistance, 120 m in water can still keep complete shape after drying fish, but by 120 m in pieces after absorbing began.

由于热风干燥鱼的收缩率较小、表面有较多缝隙，所以在吸水初期的吸水速度很快(见图4)，吸水能力很强， 120 m in 吸水率可达到1。 36； EHD在吸水初期的吸水速度均较慢，在30 m in以后吸水速度加快，当吸水时间足够时也能达到较高的吸水率，自然干燥与EHD干燥的吸水率基本相同，另外，自然干燥和EHD干燥鱼的耐水性好， 120 m in 吸水后仍能保持完整形状，而热风干燥鱼经120 m in 吸水后即开始溃散。
