Using fluid dynamics FEM (two dimensional, three dimensional andaxisymmetric) and three dimensional acoustic FEM in meticulous analysis ofexpansion muffler structure, this paper studies the influences of each mufflercomponents' position, dimension, form and quantity on the fluid dynamic andacoustic performances;therefore the paper indicates that the end of the intruding tubeis the linchpin of the fluid dynamic performance of the whole muffler structure, thespringhead of muffler fluid dynamic performance is the smoothness of air current, themain factor which affects the acoustic attenuation value of expansion chamber muffleris the grade of saltation of the section of air conducting access, and the attenuationvalue of specific frequency can be dramatically enhanced by carefully designing thelength of expansion chamber.

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。
