Abstract : as a hydrogen abstracting photoinitiator, sulfo - benzophenonehas low volatility, high sensitivity and broad photoresponse range. the binary photoinitiating system composed of sulfo - benzophenone and tertiary amine has even higher photoinitiating efficiency. three sulfo - benzophenone compounds and a new aliphatic tertiary amine were synthesized. the photographic sensitivities of binary photoinitiating systems composed ofsulfo - benzophenone and tertiary amine synthesized were measured

Fouriertransformation infro - red microspectroscopy micro - ftir technique was used to investigate the chemical compositions and structures of cutinite, vitrinite and fusinite from jurassic coals in tarim basin at different temperatures. the results show that the chemical structure of cutinite is mainly composed of long aliphatic - side chain with minor amounts of aromatic compounds. vitrinite is mostly composed of aromatic compounds, in addition to large amount of short aliphatic - side chain compounds. whereas fusinite are dominant by aromatic structure. the study indicates that cutinite is one of the best oil source - rocks, with the higher hydrocarbon - generation potential ; vitrinite is one of better gas source - rocks, and has medium hydrocarbon - generating potential ; fusinite has little hydrocarbon - generating potential. in addition, the components of aliphatic structures of cutinite, vitrinite and fusinite decrease, the aromatics are enriched and condensation of aromatic structure increases with increasing the temperature, and along with the rise of temperatures, the intensity of aliphatic structure and heteroatomic compounds decrease obviously, however the aromatic structure changes a little
應用顯微紅外光譜技術，對塔里木盆地侏羅紀煤中有代表性的3種組分角質體鏡質體絲質體在不同熱模擬溫度下的結構組成變化特徵進行了研究，結果表明：角質體結構組成中含有較豐富的長鏈脂族結構，而芳香結構和含氧官能團的含量則相對較少與此相反，絲質體結構組成中芳香烴占絕對優勢，而脂族結構含量則很少鏡質體結構組成介於角質體和絲質體之間，含有較多的短鏈脂族結構和芳香結構。 -
The expression vector prep9 was employed for the effective expression of ugt1a9 in chinese hamster lung cells ( chl ). the cell lines established were used for the study of glucuronidation in vitro, and the drug metabolism characteristics were summarized. as has been indicated that ugt1a9 mainly glucuronide hydroxyl, compounds that have aliphatic or phenol hydroxyl were selected for substrates of ugt1a9
由於botiag主要催化羥基的們醛釀綴合反應，本實驗選擇具有不同結構類型的含羥基化合物作為底物，一類是羥基處于芳環的異丙酚和撲熱息痛，其中異丙酚是gylag的專屬性底物，可以作為活性比較的參照，另一類是羥基處于脂鏈的普莢訖爾和普羅帕酮 -
