Solvent was used to decrease melting temperature and time of the resin during emulsification. 乳化中應添加助溶劑來(lái)降低萜烯樹(shù)脂的熔化溫度和時(shí)間。
Release of the welding energy instantaneously raises the contact point between the thermocouple wire and the base metal to the melting tempera ture and a fusion weld is formed. 焊接能量的釋放會(huì )把熱電偶線(xiàn)和基部材料的接觸點(diǎn)的溫度升高至熔化溫度，然后產(chǎn)生熔化焊接。
Lead will fuse at a lower temperature than some other metals. 鉛的熔點(diǎn)比其他一些金屬低。
The melting point of copper is not so high as that of iron. 銅的熔點(diǎn)不如鐵高。
