The most achievement is that we firstly obtain the analytic accurate solution of the modal fields of the waveguide structure and find some available character : ( 1 ) the different uniaxial crystal materials have the different propagation properties ; ( 2 ) when the optical axis of the crystal is on the plane that is made up of the normal direction of the waveguide plane and the propagation, there are te mode and tm mode in this special waveguide, but the principal mode is different of the character of the uniaxial crystal, the principal mode is the principal mode of te mode for the negative uniaxial crystal, but the one of tm mode for the positive uniaxial crystal ; ( 3 ) when the crystal optical - axis parallel to the waveguide plane, for the positive uniaxial crystal material, the principal mode of the waveguide is a te wave, which can be excited by the light at any frequency ; when the light frequency satisfies a single mode propagation condition, there will be only the principal mode propagating in the waveguide, otherwise some of the higher order modes can be excited, which are neither te modes, nor tm modes, but the hybrid guided modes
本文就是在此背景下，利用金屬波導和單軸晶體的一些特性，結合麥克斯韋方程組和波導的邊界條件，從三種不同的情況研究了光在對稱平面單軸晶體金屬波導（波導層是單軸晶體，兩個波導界面均為金屬）內的傳輸特性，其主要貢獻為，首次解析地得到了這種波導結構下模式場的精確解，並發現了一些有用的特性： （ 1 ）模式場的性質因單軸晶體的性質不同而異； （ 2 ）當單軸晶體光軸位於波導界面法方向與傳輸方向構成的平面內時，波導中傳輸te波和tm波，只不過其主模因單軸晶體的性質不同而異，當波導層介質為負單軸晶體時，波導主模是te波主模，而波導層介質為正單軸晶體時波導主模是tm波主模。 （ 3 ）當單軸晶體光軸位於波導面內時，對于正單軸晶體，波導的主模是橫電波te _ 0模，任何頻率的光波均可激勵該模式；當光波波長滿足一定條件時，波導內傳輸單模，否則，將激勵起高階模式，高階模即匪te波，也匪tm波，而是兩者耦合而成的混合模。 -
Based on the different direction of view and water and relation of water and land, the author divided lake landscapes into vertical single - water landscape, parallel poly - water landscape, vertical poly - water landscape, parallel single - water landscape and bird ' s - eye view landscape. addition to, the author discussed the effect of distance between a given vantage point and opposite shore to plant landscape ' s visual character, then give the key point of plant designing in different lake landscape mode and researched the effect to visual landscape caused by all kinds of plant design method from the plant on land and water

Due to its character of microscopic scale motion, a very simple position kinematic equation is achieved. based on the equation obtained, the workspace of the serial - parallel micromanipulator is described, and the effect of different structural parameters on the workspace is also discussed. in order to evaluate the output errors caused by the structural errors and actuator errors, accuracy analysis is then conducted for this serial - parallel micromanipulator, and an approach based on software programming is presented for error compensation
由於所研究的微操作機器人運動范圍很微小，機構結構誤差及驅動誤差都可能造成機器人的操作精度嚴重降低，為評價這些機構誤差對運動精度的影響，本論文以矢量法對該機器人機構進行了誤差分析，並討論了誤差補償的軟體法；此外，論文還進一步研究了遺傳演算法在並聯機器人機構學研究中的應用，為並聯機器人位置正解問題求解提出一種新思路。 -
Usually we linearize them approximately in industrial process, but in some cases this ca n ' t satisfy the request of automatic control which makes us consider the nonlinear factors in the industrial process. in practical process of power plants the typical structure nonlinear case is dead - zone and the latter case is the nonlinear variance of objects ' parametres with the changes of working condition. the nonlinear research is parallel with the linearity and adaptive method can be used to deal with nonlinear cases. in this paper two adaptive control methods are used to solve the problems brought by the dead - zone of boiler negative pressure system and the nonlinear changes of the milling system ' s character parameters, which achieved good results
在生產中通常對非線性作近似線性化處理；但在某些情況下線性近似達不到自動控制的要求，必須對生產過程中的非線性情況進行考慮。在火電廠的實際生產中，典型的結構非線性之一是死區；參數非線性多發生在控制對象特性隨工況變化而變化，表徵其特徵參數變化呈非線性。非線性控制的研究與線性控制的研究是并行的，針對非線性情況，可以採用自適應的控制方法。 -
Special attention is paid to the consequences of methanol crossover in cathode reaction and cathode over - potential. good agreement is found between simulations and experiments in regard to the v - i character of dmfcs. based on the theory of parallel electrode reaction, it becomes possible to obtain quantitatively the value of over - potential caused by methanol crossover, which is either implicit or not included in the overall cathode over - potential in previous models
