逆偏移 的英文怎麼說
中文拼音 [nìpiānyí]
逆偏移
英文
reverse migration-
The modulating signals of firing delay angle at the rectifier and firing lead angle at the inverter, and the excitation voltage are chosen to be control variables. the offset of the current of dc line and the extinction angle and the power angle of generator are chosen to be control outputs. then a nonlinear controller is designed for the system under study according to direct feedback linearization theory
以整流側觸發延遲角的調節信號、逆變側觸發超前角的調節信號以及發電機勵磁電壓作為控制變量，以直流線路電流、逆變側關斷角以及發電機功角的偏移量作為目標輸出，用直接反饋線性化方法設計了系統的非線性控制器。The frontal structure of longmenshan in the west of sichuan is very complex, showing intense structure deformation in overthrust belt, high structure amplitude, steep stratigraphic dip, developed fault blocks, complex seismic wave field, frequent change of lateral velocity, and poor image of post - stack time migration processing
摘要川西龍門山前緣構造非常復雜，逆掩推覆構造帶構造形變強烈，構造幅度大，地層傾角陡，斷塊發育，地震波場復雜，速度橫向變化大，常規疊后時間偏移處理成像效果較差。Prestack migration is performed by reverse - time migration method based on maxwell ' s equations using time - domain finite - difference method
疊前偏移用時間域有限差分求解麥克斯韋方程組的逆時偏移方法實現。Prestack migration method, based on wave motion equation, is also developed for receiver function, and compared with ray method. both p - to - s conversion wave and direct p phase contained in receiver function are migrated and imaged by reverse - time migration for data gather including all receiver functions recorded in all seismological stations for one event, and imaging profile is finally obtained by stacking for all events
本文還在接收函數射線反投影疊加成像的基礎上，提出了一種基於波動方程的接收函數疊前偏移成像方法，將同一事件接收函數中的轉換波和直達p波震相以各自的速度向深度方向逆時延拓成像，並通過不同慢度接收函數的疊加，得到最終的偏移成像結果。Any factor, among communicator, media, information, and social context, may result in false cognition during the process of communication. these factors can stimulate audience all sorts of psychological reactions, such as empathizing, perspective expectation, thought formulation, and so on. through analyzing psychological reactions of audience, i ' ll categorize false cognitions and explore the reason why false cognitions happen
傳者、媒介、訊息、社會語境（包括社會文化、民俗習慣、價值觀念、社會心態、宗教信仰等）幾個要素中，任何一種失誤都會使受眾產生各種各樣的心理反應，如：受眾的移情心理、受眾的逆反心理、受眾對傳者的角色期待心理、受眾的期待視野、思維定勢等，筆者從受眾的這些心理反應對受眾的認知偏差進行了分類，並分析其產生原因。分享友人
