Op : appear when the sensing line and sensing head is broken or the sensing ispulled out Op :為感測(cè)線及感測(cè)頭斷線或者感測(cè)拉開(kāi)時(shí)會(huì)出現(xiàn)。
Then we introduced the manufacture process of of fiber - optic fabry - perot sensing head in detail 接著對(duì)光纖fp傳感頭的制作過(guò)程作了具體介紹。
Secondly , we discussed key technics of manufacture of fiber - optic fabry - perot sensing head 其次,討論了光纖fp傳感頭的制作工藝中的一些關(guān)鍵問(wèn)題。
However , the report about the method of measuring the inner linear birefringence of optical glass sensing head is rarely to seen 然而對(duì)光學(xué)玻璃傳感頭內(nèi)雙折射的測(cè)量方法,目前還鮮見(jiàn)報(bào)道。
The characters are visually readable through the use of magnetic sensing heads in various type of magnetic - ink recognition equipment 字符可以通過(guò)各種磁墨識(shí)別設(shè)備上的磁感應(yīng)頭變成視覺(jué)可讀的。
