鄰甲氧基苯酚偶聯光度法測定水中亞硝酸鈉Based on the liquid crystal polymer theory, two kinds of polyacrylates were synthesized by choosing biphenyl group as rigid nucleus of mesophase group and six methylene chain as flexible spacing group. an important chiral additive was synthesized by choosing l ( - ) ~ 2 - octanol as chiral group. mixture was made of the additive and liquid crystalline polymer, which structure was identified by ftit, " ii nmr, dsc and pom
本論文根據液晶分子結構理論，選擇聯苯基作為介晶基元的剛性核、柔性的六亞甲基脂肪鏈為柔性間隔基，與丙烯酸反應，合成了兩種丙烯酸酯型聚合物；以拆分的l （ - ） 2 -辛醇為手性基團合成了一種液晶手性添加劑，並將所合成的手性添加劑與液晶聚合物共混，採用ftit 、 ~ 1h - nmr 、 dsc 、 pom等手段對合成的化合物、共混物進行了表徵。Synthesis, characterization and property of poly aryl ether amides from 2 - 4 - aminophenyl - 4 - 3 - methyl - 4 - aminophenoxy - 2, 3 - phthala zinone
二甲基二氮雜萘酮聯苯結構聚醚酰亞胺的合成與性能It is significant for reducing the product cost and improving the comprehensive property of the superabsorbent composite. using ammonium eerie nitrate and n, n ' - methylene - bis - acrylamide as an initiator and crosslink agent respectively, a superabsorbent composite is prepared by graft polymerization of acrylamide on starch at the presence of clay suspension, followed by hydrolyzing, washing, drying, grounding and filtering
本文以硝酸鈰銨為引發劑， n ， n -亞甲基雙丙烯酰胺為交聯劑，使澱粉、粘土接枝共聚丙烯酰胺，經過水解，洗滌，乾燥，粉碎制得粘土-澱粉接枝共聚丙烯酰胺的超吸水性復合材料。Methods the 54th generation of transformed human embryonic tendon cells and artificial composite materials of carbon fibers ( cf ) and polyglycolic ( pga ) were co - cultured in vitro to construct tet. lt was frozen in liquid nitrogen with four kinds of cpa for 2 months. post - thawed quickly and transplanted into hind limbs of nude mice, and repaired the defects of achilles tendon. after 2, 4, 6, 8, 12 weeks, the morphological, histological, ultrastructure, short tandem repeat loci and immunohistochemistry examination were detected, and biomechanical strength of tet were examined. result tendon cell survived and could secret type i collagen after 12 weeks to transplanted into nude mice. in the group of dmso + raffmose + kh2o4, vacuole in mitochondrion degraded i tendon cell ranged in order, abundant collagen fibers were found and linked each other and the biomechanical strength was increased as time elapsed. c onclusion dmso + raffmose + kh2o4 could protect tet in deep low temperature
組織工程肌腱制備完成後在四種抗凍劑保護下液氮凍存2月；快速復溫后植入裸鼠以修復跟腱缺損， 2 、 4 、 6 、 8 、 12周后取出，觀察形態學、組織學、電鏡和免疫組織化學變化，短串聯重復位點檢測和生物力學變化。結果實驗組組織工程肌腱體內植入12周后仍有肌腱細胞存活並分泌型膠原；隨著時間延長， 10二甲基亞碸（ dmso ） +棉子糖（ 30mmol l ） + kh _ 2po _ 4 （ 25mmol l ）組線粒體空泡減少，肌腱細胞排列整齊，膠原纖維增粗並連接，抗拉強度增高。分享友人
