  化学差异的
     The parameters obtained by light hydrocarbon analysis can be used not only to explain the genesis and evolution of oil and natural gas in order to study oil-gas-source rock correlation,as well as to distinguish the small chemical difference of the homologous set because of water washing,thermal alteration, or biodegradation, so as to show the preservation condition.
     利用轻烃分析技术获得的指纹特征参数,不仅可以反映油气的成因类型、演化程度,用于气—油—源岩的对比,而且还可用于同源油气形成后经水洗、生物降解、热蚀变等的影响而造成的细微化学差异的判别,反映油气的保存条件。

It has been shown that the characteristics of mica can be used as an criterion to distinguish the two genetic series of granites and as an indicator of their petrogeno-mineralization evolution. Series I is characterized by the assemblage Fe-biotite+muscovite+ilmenite+Al-rich silicates and series Ⅱ by Mg-biotite+hornblende+magnetite+Al-poor silicates. The ratio of Mg/(Mg+Fe~(2+)+Mn), another reliable criterion, is less than 0.45 in series Ⅰ and greater than 0.45 in series Ⅱ. The difference in mica chemistry in...

It has been shown that the characteristics of mica can be used as an criterion to distinguish the two genetic series of granites and as an indicator of their petrogeno-mineralization evolution. Series I is characterized by the assemblage Fe-biotite+muscovite+ilmenite+Al-rich silicates and series Ⅱ by Mg-biotite+hornblende+magnetite+Al-poor silicates. The ratio of Mg/(Mg+Fe~(2+)+Mn), another reliable criterion, is less than 0.45 in series Ⅰ and greater than 0.45 in series Ⅱ. The difference in mica chemistry in terms of MgO, FeO Al_2Q_3, TiO_2, Li_2O, F, etc. between the two series is considered to be a reflection of the chemical difference between their source regions. Apparent differences can also be noticed in DTA and infrared data between micas of the two series. Petrogeno-mineralization evolution can be demonstrated on a triangle of Li-Mg-Fe~(2+). Mg-biotite is found mainly in the coastal area of FujianZhejlang, Ninwu and along the deep faults in Nanling. In contrast, Fe-biotire and siderophyllite mostly occur in the Nanling area.

研究表明,云母特征可作为两个不同成因系列花岗岩的判别标志和成岩成矿演化的示踪。系列Ⅰ中特征矿物组合为铁质黑云母+白云母+钛铁矿+富铝硅酸盐;系列Ⅱ为镁质黑云母+角闪石+磁铁矿+贫铝硅酸盐。M(M=Mg/Mg+Fe~(2+)+Mn)是一个可靠的判据。系列Ⅰ:M<0.45,系列Ⅱ:M>0.45。两个系列云母的化学组成的明显差别主要受控于物源成分的差异。两个系列云母的差热曲线和红外光谱特征也明显不同。用Li-Mg-Fe~(2+)+Mn三角图可以反映成岩成矿演化趋势。

On the basis of the data of the chemical analyses of whole rocks (844 analyses) and minerals (49 analyses) obtained using the electron microprobe methods, the following conclusions may be drawn. 1. The chemical differences between the late Paleozoic, Mesozoic and Cenozoic basalts in eastern China can be recognized. The late Paleozoic basalts in the Southwestern Yangtze platform and the Paleogene basalts in North China and Northeast China belong to continental tholeiite. The former have higher TiO_2...

On the basis of the data of the chemical analyses of whole rocks (844 analyses) and minerals (49 analyses) obtained using the electron microprobe methods, the following conclusions may be drawn. 1. The chemical differences between the late Paleozoic, Mesozoic and Cenozoic basalts in eastern China can be recognized. The late Paleozoic basalts in the Southwestern Yangtze platform and the Paleogene basalts in North China and Northeast China belong to continental tholeiite. The former have higher TiO_2 and F_2O contents and a lower MgO content, as compared with the latter or other basalts. Most of the Mesozoic basalts are high-alumina or calc-alkaline, which have higher SiO_2 and Al_2O_3 contents and a lower TiO_2 content. The Neo- gene and Quaternary basalts are continental alkaline or per-alkaline, which are characterized by higher contents of magnesium and alkali. 2. The late Paleozoic tholeiites and the clinopyroxenes therein have abnor- mal chemical compositions, which contain more than 3. 2% of TiO_2. So it is considered that the depth of the magma generation is greater, and the upper mantle of the Upper Yangtze platform has higher TiO_2 and FeO contents and a lower MgO content than that of North China and Northeast China

本文主要探索贺兰山、龙门山和哀牢山以东地区分布的晚古生代、中生代和新生代玄武岩类在化学成分上的差异原因及其地质意义。

The morphological structures of polyimide films were studied by laser light scattering, X-ray diffraction, electron microscopy, infrared spectroscopy, cone light beam method and so on. There are obvious differences in orientation, nodules, chain-nodules, surface situation and spherulites for the PI films but no chemical differences. So various mechanical properties result from the different morphology. In addition, Azimuth Ωd can be used as a reference parameter to evaluate the orientation of the...

以小角激光光散射、偏光显微镜、X光衍射、电子显微镜、力学性能测定及红外光谱等方法研究了几种聚酰亚胺薄膜的聚集态结构。结果表明,它们在取向状态、球粒和链球结构、表面状况及球晶结构等方面有明显差异,而化学组成相同,因此认为聚集状态的这些差异是导致力学性能不同的主要原因.文中还提出方位角Q_d可作为检测PI薄膜取向状况的参照指标.
