聯苯丁酸 的英文怎麼說
中文拼音 [liánběndīngsuān]-
The present work indicates the organic nf membranes and the inorganic nf membranes all have shortages, so develop composite nf membranes that have low cost, mechanically strong and thermally / chemically - resistant, easy to cleanout and good performances is a very important task. in this paper, the preparation of inorganic - organic composite nf membranes were presented. this composite comprise a porous sio2 / al2o3 support substrate, the pore diameters of which ranging from 10 to 15 nm, this inorganic support substrate having a polymer membrane which comprises an polyvinyl alcohol ( pva ) or polyamide ( pa ) densely deposited on at least one of the face surfaces thereof, the structural porosity of such pva and pa membrane ranging from 3 to 5 nm
本論文以開發無機?有機復合納濾膜為出發點，首先在al _ 2o _ 3多孔微濾膜上利用溶膠?凝膠法制備sio _ 2 al _ 2o _ 3無機復合超濾膜作為無機?有機復合納濾膜的基膜；選用聚乙烯醇和聚酰胺為表面功能層材料，分別探討了以羥基丁二酸和磺基水楊酸為混合交聯劑，採用浸塗法制備了聚乙烯醇sio _ 2 ? al _ 2o _ 3復合納濾膜；以均苯二甲酰氯、哌嗪和二胺為單體，採用界面聚合法制備了聚酰胺sio _ 2 ? al _ 2o _ 3復合納濾膜，並對影響膜性能的諸多因素進行系統研究。Several polysubstituted biphenyl compounds containing four skeletons were firstsynthesized from ellagic acid via a reduction with dibal - h. the cytotoxicity activities of these compounds were evaluated against human tumor cells in vitro
以鞣花酸為原料經關鍵的二異丁基氫化鋁還原首次合成了數個擁有4個骨架的多取代聯苯化合物，並對其人類腫瘤細胞毒活性進行了體外測試。( iso ) thiocyanate method is also called schlack - kumpf degradation. we spend much time on the derivatizing reagent which is extremely crucial to this method. four derivatizing reagents that seemed theoretically practical have been introduced, after thoroughly invest igation of them, two of which are practical and can derivatizing the amino acids to their corresponding thiohydantoins : ( 1 ) tributylsilyl isothiocyanate ( tbus - itc ) ; ( 2 ) triphenylgermanium isothiocyanate ( tpge - itc )
（異）硫氰酸法又稱為schlack - kumpf降解，本文在關鍵的偶聯試劑方面進行了不懈的努力，先後對理論上有可能成為偶聯試劑的四種化學試劑進行了摸索，最後確定了其中兩種是可行的： （ 1 ）三丁基硅異硫氰酸酯（ tbus - itc ） ； （ 2 ）三苯基鍺異硫氰酸酯（ tpge - itc ） 。
