In this paper, the relationship between component and melting point of fluorine free mould fluxes was studied by means of regressive orthogonal design. 論文利用二次正交回歸的設計方法對無(wú)氟保護渣的成分與熔點(diǎn)的關(guān)系進(jìn)行了研究。
Shrinkage occurs in two parts - as metal superheats above the melting point and has losses, causing shrinkage, followed by further shrinkage during solification. 收縮發(fā)生在兩個(gè)過(guò)程中，溫度高于熔點(diǎn)的金屬冷卻時(shí)產(chǎn)生收縮，隨后在凝固過(guò)程中進(jìn)一步收縮。
The Luobusha podiform chromites locate at metamorphic peroditites that show partial melting and dynamic remelting. 羅布莎豆莢狀鉻鐵礦床產(chǎn)于高度部分熔融和動(dòng)力重熔的變質(zhì)橄欖巖中。
