I took this picture with a red filter. 這張照片我是用紅色濾光鏡拍攝的。
A filter designed to capture plaque and other debris freed from the arterial walls during the procedure was also used during stent implantation. 一種濾光鏡設計用來尋找斑塊和其他從動脈壁上遊離的碎片，同時它也在安放支架時候使用。
A filter for a display apparatus, a method of manufacturing the same, and a plasma display apparatus are disclosed. 本發明公開了一種用於顯示設備的濾光器及其製造方法，和等離子體顯示設備。
The filter funnels the signals received from many directions into separate photodetectors and improves reception by combining the energies of the beams. 濾光器把來自許多方向的訊號導入個別的感光器，並將光束能量合併以改善接收品質。
