Research on the Removal of Thiophene-type Sulphide by Gamma Rays Radiation Assisted with Carbon Tetrachloride 四氯化碳协同γ射线辐射去除噻吩型含硫化合物的研究
In this thesis, a novel approach is presented for bulk uniform graft-modification of vinyl monomers to pre-existing polymeric materials by combining gamma(γ)-ray pre-irradiation-induced graft copolymerization and supercritical carbon dioxide ( SC-CO_2)-swelling polymerization techniques. 本论文提出一种结合超临界二氧化碳溶胀聚合技术和γ-射线预辐射接枝技术的优势,实现对已成型聚合物材料进行整体均匀接枝改性的新方法。
Carbon/ oxygen spectrum technique uses the ratio of characteristic gamma ray of carbon versus oxygen when fast neutron and formation have non-elastic dispersion to determine oil saturation. It is used in logging industry for many years. 碳氧比能谱技术主要是利用快中子与地层发生非弹性散射时产生的碳和氧的特征伽马射线的比值来确定套后含油饱和度,在测井行业已成功地使用了多年。
Coal samples are radiated by~ ( 241) Am-Be neutron source. The induced prompt gamma rays by neutron are measured. We determined the contents of carbon and hydrogen in coal samples by characteristic gamma rays. 用~(241)Am-Be中子源照射煤样,测量中子感生的瞬发γ射线能谱,由特征γ射线的强度来确定C、H含量。
