扇出率 的英文怎麼說
中文拼音 [shānchūlǜ]
扇出率
英文
fan ratio-
By analyzing the basic principle of voltage space vector pwm, a method is proposed to choose the zero vectors dynamically according to the power factor angle of the load and the concept of the lag angle of non - switching sectors
在分析了空間矢量pwm基本原理的基礎上，提出了一種根據負荷功率因數角動態分配零矢量的方法，並引入了不開關扇區滯后角的概念。The narrow fan - beams are reset into parallel beam then the image reconstruction is conducted by parallel beam " convolution back projection algorithm, which combines the high scan efficiency with the convenience of image reconstruction. this paper analyses the parallelism in narrow fan - beam " convolution back projection algorithm, divides the task of image reconstruction into several subtasks, and discusses the parallelization of narrow fan - beam " decomposition and reset, parallel beam " convolution back projection, and image accumulation
對于窄角扇束掃描方式，把窄角扇束重排成平行束，再由平行束卷積反投影重建演算法來重建圖像，是把掃描的高效率和重建方式的簡便易行很好的結合起來。本論文對窄角扇束卷積反投影演算法進行了并行性分析，指出把圖像重建任務分解為多個子任務并行工作，並在工作站機群上討論了窄角扇束的分解、重排、平行束卷積反投影圖像重建、圖像合成的并行實現。
