composition of sample meaning in Chinese

样本的构成

The composition of sample was identified by means of x - ray diffractometer ( xrd ) . magnetic properties were measured by vibrating sample magnetometer ( vsm ) . the combustion behavior and crystallization process of the gel were studied by means of differential thermal analysis - thermogravimetric analysis ( dta - tg )
利用x射线衍射仪( xrd )确定样品物相，振动样品磁强计( vsm )进行磁性测量，综合热分析仪研究凝胶的燃烧和析晶过程，扫描电子显微镜( sem )和透射电子显微镜( tem )观察粉末的形貌与粒度。
Absorption - band parameters such as the position , depth , width , and asymmetry of the feature have been used to quantitatively estimate composition of samples from hyperspectral data . so spectral absorptions are very important feature bands in use of hyperspectral classification and targets identify , this paper extracts absorption features of actual hyperspectral image by continuum removed method which is very useful . then tested both of them by
吸收峰波段参数例如波长位置、深度、宽度、斜率、对称度、面积等常常被用来定量的估计高光谱样本的组成,因此光谱的吸收峰是高光谱识别分类应用中很重要的特征波段,论文通过包络线去除这种很有效的光谱分析工具提取出了实际的高光谱图像的地物光谱的吸收峰参数。
