变质程度煤样中相对含量的变化较小，而在高变质程度煤样中的相对含量明显减少；酚中C —O 的相对含量 呈先增后减趋势，芳基瞇与烷基醞的相对含量逐渐增加，并成为无烟煤中的主要含氧官能团。在芳香疑结构 方面，苯环取代以三取代为主，结构参数冗与DOC 逐渐变大，说明煤中芳香体系增大，芳香结构缩合程度 逐渐...
不同煤阶煤表面改性的FTIR谱研究
Heavy Ion Implanter (IMP, Lanzhou) to the dose ranging from 2.0×10^17C/cm^2 to 8.6×10^17C/cm^2,The irradiation was performed at CARIL-GANIL,Caen,France to the fluence ranging from 5.0×10^11Pb/cm^2 to 3.8×10^12Pb/cm^2.Some parameters were given in Table 1(TRIM 96 calculation...

The composted OWP had in general lower percentages of mineralisable carbon (Cm3-91) as well as lower C/N ratios than the non-composted ones due to the organic matter degradation that took place during the composting phase before soil incubation (Table 1). Meanwhile, a higher mineralisable ...

Ratios are calcite:aragonite. Table 1. Intensity values and normalized heights for calcite and aragonite in mixed polymorph samples (C: calcite; A: aragonite; N: normalized). The quantification of archaeological samples (C:A ratio) is based on XRD. ...
Table 1 shows the variation in the cell parameters, volume, density, and APF against the Fe3+ concentrations. From Table 1, since the ionic radius of Fe3+ is larger than that of Co2+, the cell parameters (𝑎a and c) of the co-doped samples increase as the dopant concentration ...
