常見例句雙語例句The relief structure of diffraction optical element can be written precisely but very slowly with the raster scan mode bye-beam.用電子束逐行掃描方法刻蝕衍射光學元件的浮雕結(jié)搆精度高而速度低。Display systems must"look" for this negative going edge in order to identify the moment intime when to re-sync the raster scan process.顯示系統(tǒng)必須“找到”這個負極性的下降沿,以便確定重新同步光柵掃描進程的時刻。The issue of polar coordinate-orthogonal coordinate conversion, which is a key factor of the system, may be encountered inevitably as simulating traditional PPI radar indicator on raster scan display.在光柵掃描顯示器上模擬傳統(tǒng)PPI雷達顯示器,不可避免地會遇到直角坐標與極坐標轉(zhuǎn)換的問題,而雷達廻波信號從極坐標到直角坐標的變換是決定系統(tǒng)性能的關(guān)鍵。 返回 raster scan
