The piston moves up and down in the piston chamber primarily in response to changes in intake manifold vacuum.
活塞主要因进气歧管真空度的变化而在活塞腔内上下移动。

Vacuum sputter coating has better stability than smearing film while smearing film has better response electric characteristics than vacuum sputter coating.
真空镀膜稳定性比涂膜好，涂膜的响应、导电性比真空镀膜好。
