如何在大概0.1pa的真空室用BNC將導(dǎo)線引出來？
本人看的文獻上說用的是焊接，但會有發(fā)裂（hairline crack），這樣會破壞真空，需要用檢漏裝置探測發(fā)裂（原文：The valve and BNC connectors were welded onto the flanges nu -wQr
and we think it likely that a hairline crack is responsible for the bad performance of the vacuum.）。請問專業(yè)人士如何在不破壞真空的情況下將導(dǎo)線引出。 PHx No) "t`e68{Ls
本人是新手，希望能詳細解答。謝謝!
