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氟保護渣的成分與熔點的關係進行了研究。
Shrinkage occurs in two parts - as metal superheats above the melting point and has losses, causing shrinkage, followed by further shrinkage during solification. 收縮發生在兩個過程中，溫度高於熔點的金屬冷卻時產生收縮，隨後在凝固過程中進一步收縮。
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於高度部分熔融和動力重熔的變質橄欖岩中。
