In order to explore the relationship between the Artemisia frigida Wild. and the intake mass, this reaserch took sheep as reaserch object, using mixture of pasture containing A. frigida in different scales to feed sheep, to analyse the intake mass of the sheep, intake behavior and diet selection strategy, combined with Thermal-desorption Cold Trap/Gas Chromatography/Mass Spectrum to analyse the VOCs from the overground part of A. frigida in July and to identify the compoments; and its major components cineole,α-terpinol ,α-pinene andβ-pinene were added to the sheep feed, to analyse the effects of different monomers of VOCs from A.

为了探讨冷蒿与家畜采食量的关系，本实验以绵羊为研究对象，用含有不同比例冷蒿的混合牧草饲喂绵羊，分析了绵羊的采食量、采食行为及食性选择策略，结合热脱附―气相色谱―质谱联用技术对冷蒿地上部分7月份释放气体进行了组分分析和鉴定；并将其主要成分桉树脑、α-萜品醇、α-蒎烯和β-蒎烯添加到绵羊的饲料里，进一步分析了不同冷蒿挥发物单体对绵羊采食量、采食行为及食性选择策略的影响。

Vibrational circular dichroism is a useful technology to measure the circular dichroism of chiral molecules in the IR region, which remarkably expands the application of circular dichroism to the determination of AC.

振动圆二色谱是在红外波长区域测定分子圆二色性的一种新方法，极大地扩展了圆二色谱的应用范围。

Lattice dynamics simulation of ice Hi and clathrate hydrates has been carried out to study the corresponding structural and dynamic properties. Comparisons in PDOS of them were performed and it was found that the spectra resembled each other in both translational and librational regions, which seems to contradict the substantially different lattice structures.

论文用晶格动力学的方法模拟了六角冰和笼型水合物的结构和动力学性质，通过比较其声子振动谱密度得出两者的振动谱在平动区和摆动区都有很强的相似性，这与两者差异巨大的晶格结构很不相称。

AVO analysis is suggested for solving to solve the difficulty in identification of thin alternating layers in exploration of oilfields. It can improve the current method that has no thickness variable in the formula of reflective and is limited by sampling rates in calculation of the coefficient in the time of domain. Using the relationship of stress and displacement on two interfaces, this paper derives the spectrum of reflective coefficient for any incidence angle and thiekness of thim layer based on the equation of seismic wave propagation in the frequency domain.

针对油气田开发中薄互层认识难的问题，提出从AVO分析解决困难，克服现有方法在反射系数公式中无厚度变量、时间域计算反射系数谱受采样率限制的不足，运用两个界面间位移与应力关系，从频率域地震波传播方程推导了任意入射角和薄层厚度下的反射系数谱。

However, this polynomial regression model suffered from thecolor metameric problem. Herewith, to minimize the metamerism, a model was developed based on the principal component analysis and back-propagation artificial neural network for scanner spectral characterization, which could reconstruct more accurate spectrum in comparison with the related international experimental results.

但是，扫描仪的多项式回归色度特征化模型存在同色异谱问题，因此本文提出了基于主元分析法和神经网络技术实现扫描仪颜色光谱特征化的算法模型，解决了同色异谱的问题，并且获得了比国际上同类研究更高的图像光谱重构精度。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
