利用超巨磁電阻材料製作工作于室溫的高性能測輻射熱儀是國際上cmr應用研究的一個重要方向，而能否制備具有室溫轉變點的薄膜材料是其中的一個決定因素。Nonlinear directional coupler ( nldc ) is a switch used in optical network. w. s. man had studied transmission controlling with ground state soliton through nldc, it is obviously not available to used in superhigh speed network ; and mary j. potasek had studied the self - coupling with ultrashort solitons in nldc, self - coupling is difficult to control the signal transmitting. i has studied the transmission controlling with ultrashort solitons ( < 100fs ) in nldc, similarly i use a controlling pulse to control the signal pulse, it is the intensity of controlling pulse to decide the signal change its direction or not
非線性定向耦合器（ nldc ）是用在光網路中的光開關器件，它主要用在全光網路中， w . s . man等研究過基態孤子在nldc中的傳輸控制，便於對全光網路中數據的正確傳輸，由於目前研究集中在100fs的超短脈沖傳輸特性上，顯然基態孤子的特點不再適用於超高速網路； maryj . potasek等就超短脈沖在nldc中的自耦合做了研究，在光網路中自耦合任意性太大，不利於控制脈沖的傳輸。This strategy has many advantages : solving the problems that the system is unsteady under super - synchronization ; improving power factor of stator ( it is unity relative to that of rotor ) ; no rotor position sensor and no initial position measurement, easily building up doubly fed speed adjustment system with speed sensorless because adjusting speed is taken in the rotor coordinate and rotor current vector fixing is implemented
該方案由於引入了定子電流勵磁分量的閉環控制，使系統同時具有轉速和勵磁調節兩個調節通道，具有如下優點：一、解決了超同步工作工況不穩定的問題；二、提高了定子側的功率因數（與轉子側功率因數為1相比） 。三、由於速度調節在轉子坐標系下進行，並以轉子電流矢量定向，所以無須轉子位置傳感器，也不用檢測初始位置，易於組成無速度傳感器雙饋調速系統。For example, the large friction loss of prestressed tendons, complex anchorage bearing joint, the problem of cracks in large area structure, axial compress of long span continuous beam under prestress. all those hinder its use in long span structure. until now days, the cognition about the behavior of such structure under loads is not enough for the realm of prestressed concrete of all the world
