Terahertz time-domain spectroscopy (THz-TDS) has been used to probe the evolutionary paths of kerogen in selected black mudstone. The evolutionary regime of kerogens (for instance, the immaturity, early maturity, middle maturity, late maturity, and catagenesis stages) can be indicated by the absorption coefficient in the THz region. The present study of identification based on THz-TDS was in good agreement with programmed pyrolysis experiments and suggests that THz technology can act as a nondestructive, contact-free tool for probing the ability to generate hydrocarbons from kerogens.

The application of terahertz（THz） technique in many fields like petroleum industry requires the high resolution and multifunction to realize the precise detection of different materials. In this study water vapor in atmosphere was scanned with shortand long-path THz spectrometers with different scan ranges. The full width at half maximum of the THz characteristic lines in long-path system reached less than 7 GHz and that in short achieved -5.5 GHz, indicating that the THz spectroscopy of water vapor can be used to calibrate THz devices. THz systems with right scan ranges could be a promising selection for the identification of solid, liquid and gaseous materials with very similar structures due to the high resolution. The research demonstrates that the multifunctional THz test can be realized through the balance of resolution and sampling space in many fields, such as oil-gas industry.

Haze or smog episodes, which are characterized by the presence of particulate matter at diameters less than 2.5 μm （PM2.5）, have attracted increasing attention during the past few decades [ 1 ]. PM2.5 has adverse effects on human respiratory health as well as on air visibility [2,3]. In the Beijing-Tianjin-Hebei （BTH） region of China, haze has become especially serious in recent years because of industrial expansion and traffic-related emissions [4,5] （http：//***/english/2016-01/07/c_***; http：// ***/html/2016-01/07/content_***）. To protect public health, the first-ever red alert for smog in China was issued by the Beijing municipal environmental protection bureau （MEPB）,

Gas hydrates are crystalline clathrate compounds comprised of hydrogen-bonded water cavities, consisting of guest molecules trapped in a lattice of polyhedral water cages under elevated pressures and low temperatures [1]. The structures of the gas hydrates are closely related to the types and sizes of the guest species, and three distinct structures, including cubic structure-I （sI）, hexagonal structure-H （sH）, are cubic structure-II （sII）, and known to form [2].

Dear Editors, The merit of coal has been recognized by average people, whereas the value of oil shale has not been realized even by some experts in energy field. Compared to coal, oil shale also has dark looks and giant reserves while the content of ash in oil shale is higher. Owing to organic matter it con- tains, a sort of fuel named shale oil can be extracted via pyrolysis, which resembles crude oil in composition and can be further processed to obtain gas and diesel .

使用太赫兹时域光谱技术对生物饲料添加剂中的地衣芽孢杆菌、枯草芽孢杆菌、凝结芽孢杆菌三种益生菌进行了室温、充氮环境下太赫兹时域光谱测试。得到了样品在0.2~1.6 THz波段的太赫兹吸收光谱和折射率谱。实验结果表明,随着频率增加三种益生菌的THz波段的吸收系数是增加的,并且有不同的吸收趋势及明显的特征吸收峰,这意味着三种样品的分子及官能团的构成和存在状态是不同的。三种样品明显不同的平均折射率(分别是1.71,1.67,1.64)说明太赫兹光通过样品时所产生的色散和吸收是不同的,这更有力地揭示三种样品的确具有不同的生物成分组成和结构。为了更好地比较和说明太赫兹波识别鉴定益生菌的优势,还进行了同条件下的红外测试。通过对比发现菌制剂在太赫兹波段比在中红外波段更具有吸收活性,更能体现其结构差别,是红外光谱测试的有效辅助手段,同时,文中还依据益生菌的生物结构特征首次给出了机理上的解释和探讨。这项研究表明太赫兹时域光谱技术能够填补益生菌检测手段的匮乏,为益生菌的检测乃至为其它生物饲料添加剂检测提供了一种行之有效的方法。
