manganin n.錳銅;錳鎳銅齊。

manganite

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于可以采用高壓絕緣性能更好的無機物作為絕緣封裝材料,如本研究中所采用的sio2 ,而代替在箔式錳銅計中所使用的ptfe ;并可實現敏感元件“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。

In the early stage of experiment , an in - material thin film manganin gauge was studied . this in situ gauge was manufactured by single - step thin film processing , namely , manganin piezoresistance element was prepared on inorganic substrates such as ceramic , microcrystalline glass , etc by sputtering 在實驗的初期,本文還研究了“在位式”的錳銅薄膜傳感器,即首先在陶瓷或微晶玻璃基板上沉積錳銅敏感元件,然后用粘貼ptfe薄膜的方法完成傳感器的封裝。

5 . manganin thin films with low temperature coefficient of resistance were prepared by magnetron sputtering . the changes of tcr under difference deposition and heat treatment conditions were studied 首次采用磁控濺射法沉積了低電阻溫度系數的錳銅薄膜,研究了在不同電子科技大學博士學位論文沉積及熱處理條件下薄膜tcr的變化。

Then , a thin layer of ptfe film is glued on the surface of the manganin film to package the sensing element . the response time of this gauge was found to ralated to the mounting mode of the transducer 實驗發現該傳感器的響應時間與安裝方式有關,當基板正對飛片時,響應慢;而ptfe薄膜正對飛片時,響應快。

Based on impedance match method , the measurement range of the gauges can be extended to 100 gpa and above . this range is about 1 time higher than that of exiting manganin gauges 根據阻抗匹配原則,首次使“后置式”傳感器的有效量程達到了100gpa以上,比現有傳感器的量程上限提高了1倍多。
