查询词典 poly

Poly lactic acid is a biodegradable and processable high polymer, which is widely used in chemical engineering, agriculture and pharmaceutical industry. D-LA is hence going to form a huge potential market. Fermentative production of D-LA by microorganisms is the primary method in industry, which is applied by several factories abroad.

聚乳酸因具有优良的生物可降解性和加工性能，应用于化工、农业和医药等方面，因而D-乳酸市场潜力巨大。D-乳酸的工业生产主要应用微生物发酵法，国外已有2~3家D-乳酸生产企业，而我国目前尚无D-乳酸制备研究或工业化生产的报导，该技术亟待发展。

E. OCB mode LCD elements . Then,we added bi-functional powder and LC E7 in the bulk copolymer of Poly Acrylic Acid and EOPO,then poured the LC solution,and exposed it with 5V voltages under ultraviolet radiation. Finally,we observed the changing phenomena of the planar display of OCB cell with additional external voltage under polarized microscopy . It can be observe obviously the polymer wall in OCB cell when NO.4 LC solution having concentration of 3％ wt . At the same time,the polymer which didn't sheltered by mask will polymerize,then,lead LC into high inclined angle alignment. And it formed discontinuous structure along mask affected LC which surrounded the wall. The results measured by photoelectric instruments showed the discontinuous structure not only keeps the inner LC structure at twist mode,but also promotes the originated respond-velocity of OCB.

然后利用聚丙烯酸与EOPO之团聚共聚合物，添加双官能基粉体及液晶E7，制备成液晶溶液再注入液晶盒里，放置光罩并给予固定外加5V电压在UV下进行曝光，然后在偏光显微镜下外加电压观察液晶盒的平面显示变化现象，发现四号高分子的液晶溶液在3%时，可以明显观察未被光罩遮蔽的高分子将会聚合形成高分子格子结构，并造成液晶成高倾角排列，顺著光罩形成不连续的结构藉以影响墙周围的液晶，从光电量测结果显示，利用此种不连续结构不仅可将内部液晶结构维持在twist的状态，也成功提升OCB原有的响应速度。

HE STARTED out as Richard A. Gekoski, a gawky American high-schooler focused only on discovering sex, and morphed into R.A. Gekoski, a fully fledged, if miserable, academic teaching English literature at a provincial British university. Only in his mid-50s, having abandoned academe and an unhappy marriage, and high-tailed it to London, did he discover who he really was: Rick Gekoski, a roly-poly book dealer with an appetite for all things big and a passion for Groucho Marx's motto:" Outside of a dog, a book is a man's best friend. Inside of a dog, it's too dark to read."

开始，他叫做理查德·A·杰柯斯基，那时他还是个上高中的傻小子，专注于探寻鱼水之乐；之后，他蜕变为R·A·杰柯斯基，一位羽翼已丰的英文文学教员，就职于一所英国地方性大学；而直到他五十五岁左右之时，在放弃了他的学术和一桩并不愉快的婚姻然并奔向伦敦后，他方才找出真正的自我——里克·杰柯斯基，一位胖滚滚的书商，对所有大块物件都有个好胃口，并痴狂于葛洛丘·马克思的名言：&书于犬外，人之挚友；书于犬内，暗不能阅。&

The liquefied Japanese cedar was blended with PMDI (poly-4, 4'-diphenylmethane diisocyanate), and adding water as a blowing agent, organosiloxane as a surfactant and dibutyl tin dilaurate as a catalyst to prepare the polyurethane foams. The effects of the kind and dosage of surfactant and the molar ratio of NCO/ for PMDI to liquefied Japanese cedar on the properties of PU foams were investigated.
