The addendum of the . vearc Roots rotor prises . vesmoothly connected circular arcs, while the dedendum portion consists of conjugate curves. The top land of the. vearc Roots rotor is wider than the traditional Roots rotor. 結(jié)果2:略實例二:檢索課題:真空泵網(wǎng)站:Springer Link網(wǎng)址:檢索方式:“Advanced Search”中的“Articles by text”檢索字段:title檢索詞:vacuum pump邏輯關(guān)系:all word結(jié)果1:論文題名:Advanced performance of small diaphragm vacuum pumps through the use of mechatronics作 者:R.
