粉末状态

When the molten copper temperature at 1200 and the content of Alin mixed-powder more than 16.5%, the microstructure and properties of the Cu-Al2O3 composites were more satisfying.

熔液温度为1200℃且混合粉末中Al含量大于16.5％时，材料组织性能较好；Al含量小于16.5％时，Cu_2O与Al在铜熔液中的反应受物质的微观运动状态影响较大，反应进行得不均匀。

The thermal behavior of silver behenate has been studied by infrared spectroscopy, X-ray diffraction, combined thermogravimetry-differential thermal analysis-mass spectrometry. The results indicated that complicated phase transitions took place while heating silver behenate,but there were two distinct thermal transitions. During the first transition at 138°C, the alkyl chains of silver behenate were transformed from an ordered into disordered state.

通过采用粉末X射线衍射、红外光谱、热重-差热分析与质谱联用技术，对山嵛酸银纳米晶体的热行为研究发现，山嵛酸银受热发生了一系列相转变，它有两个明显的突变：即在138℃左右，山嵛酸银的烷基链从高度有序转变为无序状态；在231℃左右，山嵛酸银发生了热分解，其主要分解产物为银纳米粒子和山嵛酸。

ABSTRACT The content of constituents in YongAn middlings and Zhongliang shan middlings has been calculated in light of the results of ultimate analysis and X-ray diffraction, and the structure of middlings has been studied by means of polarizing microscope.

本文以高灰低硫的永安中煤（Ad=51.11%，St=0.35%）和低灰高硫的中梁山中煤（Ad=32.29%，St=3.02%）为研究对象，首先利用中煤灰成分化学元素分析和X射线粉末晶体衍射的矿物成分分析结果，通过计算求出了中煤中各组成成分的含量，并借助偏光显微镜对中煤矿物质的赋存状态进行了研究。

It also has steadying air pressure and storing air function that can ensure pneumatic parts steady and reliable performance.
