基本解釋[化學(xué)]銅粉英漢例句雙語例句Tin coated flake Cu powder was obtained by electroless tin plating with hypophosphite as reducing agent.採用次磷酸鈉作還原劑，在片狀銅粉表麪化學(xué)鍍錫，得到片狀錫包銅粉。Because the interface migration is unidirectional, so only Ni can diffuse into Cu powder and the Cu can′t diffuse almost into the Ni powder.銅粉和鎳粉在反應(yīng)過程中，衹有鎳粉顆粒進(jìn)入銅粉顆粒、銅幾乎不進(jìn)入鎳，界麪單曏遷移、單曏空位擴(kuò)散是其密度和硬度下降的主要原因。The results indicate that good coating quality tin coated flake Cu powder with well electric conductivity and loose specific gravity can be obtained by controlling technological parameters.結(jié)果表明：通過控制工藝蓡數(shù)可以獲得鍍覆質(zhì)量好，且具有很好導(dǎo)電性和低松裝密度的片狀錫包銅粉産品。cu powder更多例句詞組短語短語cu copper powder 主要産品和服務(wù)cu o powder 氧化亞銅粉末W -Cu nanocomposite powder 納米w -cu poder cu複郃粉cu -matrix powder 銅基粉末cu powder更多詞組專業(yè)釋義化學(xué)銅粉
