錳銅壓力計 的英文怎麼說
中文拼音 [měngtóngyālìjì]
錳銅壓力計
英文
manganin gauges-
Manganin gauge is a kind of special sensor which is mainly used to measure the ultra - high pressures generated by shock waves
錳銅計是一種特種傳感器,主要用於測量沖擊波產生的超高壓力。The main conclusions and original results are summarized as follows. the manganin ultra - high pressure sensors for gas gun were made by two - step thin film techniques, namely, manganin thin films were first deposited by magnetron sputtering on fused silica substrates, and then covered by a layer of sio2 thin films by electron beam evaporation. consequently, the manganin sensing elements were " cleanly " encapsulated in inorganic solid matrix and the high - pressure shunt effect was eliminated radically
上述技術的主要優點在於可以採用高壓絕緣性能更好的無機物作為絕緣封裝材料,如本研究中所採用的sio2 ,而代替在箔式錳銅計中所使用的ptfe ;並可實現敏感元件「清潔」地無機固態封裝,即將整個敏感元件是包封在無機物中,而不與高壓力下絕緣性能相對較差的有機物,如粘接劑、樹脂等直接接觸,從而在根本上消除了高壓旁路效應。Although the highest pressure in copper target was 107 gpa and that in alumina packaging was in the vicinity of 70 gpa, the gauge records showed a good plateau of about 1 um in duration and absence of shunt
實驗中銅靶板上的最大壓力達到了107gpa ,氧化鋁封裝中的壓力也達70gpa以上,薄膜式錳銅計輸出的信號波形完整,壓阻信號的平臺持續時間長,無明顯的旁路存在。
