1，tightened是什么意思

tightened v. 收緊( tighten的過去式和過去分詞 );（使）變緊;（使）繃緊;加緊[例句]Last year the obama administration tightened them further.去年奧巴馬當(dāng)局進(jìn)一步收緊了這項政策。

有將snug-tightened翻譯為“適當(dāng)擰緊”，我認(rèn)為“密貼擰緊”更合理，為了不引起異議，國內(nèi)通常翻譯為“密貼初擰”。是指高強螺栓安裝的第一步，國內(nèi)稱為初擰，目的是使接點板疊的摩擦面緊密接觸，形成“密貼”狀態(tài)。也就是將螺栓擰緊到將鋼結(jié)構(gòu)接點板疊之間緊密貼合，此時，螺栓剛剛被拉緊，并產(chǎn)生輕微的彈性變形，將板疊壓緊在一起。
