IR and fluorescence microscopy in addition to the measurement of their homogenization temperatures (T\-h). Two populations of organic inclusions were recognized, the primary and the secondary organic inclusions. The primary organic inclusions contain organic materials with relatively long alkyl chains (the carbon atom number is 15 to 17), whereas the secondary organic inclusions contain a certain amount of H\-2S besides organic materials which have relatively short alkyl chains with the carbon atom number of 5 to 6. The T\-h values of the primary organic inclusions are within the range of 87-91℃, lower than those of the secondary organic inclusions (T\-h=98-105℃), suggesting that the primary organic inclusions experienced a lower degree of thermal evolution than the secondary inclusions. This inference is consistent with the fluorescence spectroscopic characteristics and parameters (T\-\{max\}, Q values) of the organic inclusions. Data from the organic inclusions together with the petroleum geology setting revealed that the primary inclusions resulted from the migration of hydrocarbons generated within the strata they are hosted, whereas the secondary organic inclusions were trapped in the process of secondary hydrocarbons expelled out of the source rocks to the locations where they were accumulated. The thermal properties of the organic inclusions are consistent with the maturation of the oil generated from the Shahejie Formation. The abundance of the organic inclusions and their characteristics indicate that the member Es3 of the Shahejie Formation is highly potential for oil accumulation. The results could provide essential clues to petroleum exploration in the Bohai Gulf Basin.展开更多

The coal-bearing series of Carbonifer ous-Permian in the hasin distributes extensively. The micro-FT-IR analysis of the chief macerals shows that the cutinite and resinite are rich in CH3 and CH2, but the sporinite is deficient in that. The desmocollinites in the C-P coals are all rich in CH2, however, the same parameters (ICH3,ICH2,,IA) of coals in Taiyuan Formation (C2t ) are greater than that in Shanxi Formation (P1s), which revealedthat the coals in Taiyuan Formation is more abundant in Hydrogen.展开更多

In this paper, we focus on how to investigate the micro-motion dynamic characteristics of the ballistic targets from the signals based on infrared (IR) detection, which is mainly achieved by analyzing the periodic fluctuation characteristics of the target IR irradiance intensity signatures. Simulation experiments demonstrate that the periodic characteristics of IR signatures can be used to distinguish different micro motion types and estimate related parameters. Consequently, this is possible to determine the micro-motion dynamics of ballistic targets based on IR detection.展开更多

The metal nano layer will attract the micro-poisons from any measured aqueous sample increasing the concentration of the micro-poison in the vicinity of the surface and significantly improves the sensitivity of the spectroscopic measurement. The demonstration was carried out using Fourier Transform Infra-Red (FTIR) operating in the MIR 400 cm-1 - 4000 cm-1 and 5 nm Gold layer which was grown on silicon oxide substrate. In the experimental demonstration Malathion organophosphate pesticide was used as micro-poison. The spectroscopic measurement proves that Malathion was attracted to the metal nano layer. Furthermore, the absorption lines of Malathion were detected and recognized. This proof of principle can be applied to any Internal Reflection Elements (IRE) and it can be used to purify any aqueous solutions and atmosphere from micro-poisons which will be attracted to the metal Nano layer.展开更多
