轉變雙晶 的英文怎麼說
中文拼音 [zhuǎnbiànshuāngjīng]
轉變雙晶
英文
transformation twinning-
When we applied electric field, the the oritation of liquid crystal molecule axis reset. it induced the roate of optic axis. at last, the birefringence will change. this is the voltage - dependent birefringence of liquid
例如當對液晶施加電場時，液晶分子軸的排列會變化，從而引起液晶光軸的轉動，最終導致了液晶雙折射率的變化，這就是我們所說的液晶電控雙折射特性。The tunable performance is obtained by rotating the grating. the disadvantages of the mechanical tunable filter are high control voltage, slow response time and big volume. the electro - optic tunable filters are obtained by the alteration of the birefringence of the electro - optic material applied voltage
電子光學濾光片則是通過施加電壓使各種電子光學材料的雙折射率發生變化來實現透射波長的調諧，也可以利用電光晶體在電場中的旋轉來實現波長的調諧。The second stage is stage of the matter transfers the activated matter, that is to say, minerals build up their surface area after passing though physical weathering, maifan stone form a lot of clay mineral, oxide, oxhydroxide and collide mineral after passing though chemical weathering. it makes nutrition elements transform from crystal state to adsorption state and it expands the activation of mineral, in the latter stage, it makes maifan stone have many special physicochemical adjusting character, for example, ph and foi bi - directional absorptive and ion exchange character, so these characters expand maifan stone ' s uses
第二階段為物質轉變的活性階段，即通過物理風化增大表面積、通過化學風化形成大量粘土礦物、氧化物和氫氧化物及膠體礦物，使營養元素由結晶態轉變為吸附態，從而大大增加了其活性。在後一過程中麥飯石還形成了許多特殊的物理化學性質，如ph值和f _ （ o2 ）的雙向調節性，吸附性和離子交換性等，從而擴大了其用途。This paper make a study of controller on permanent magnetsyn - chronous motor. the permanent magnetsyn - chronous motor has many virtue such as simply structure and simle solidity etc. with this excellence. it has more and more uses in industry and agriculture. the idea of this paper is to control permanent magnetsyn - chronous motor system through vector control. to solve the problem of pid regulator, we use the fuzzy control and self adaptive pid
本文設計的思路是採用轉子磁通定向的矢量控制技術，主電路採用spwm和交-直-交電壓型逆變器，其中spwm採用sa4828晶元直接產生，在控制器的實現方面，採用了tms320lf2407型dsp晶元作為主控板cpu ，實現了電流、轉速雙閉環的控制系統。The property of freedericksz transition and the bistable state for nematic liquid crystal ( nlc ) cell in the surface physics of liquid crystal ( lc ) have been one hot point of current lc science
