常見例句雙語例句The petroleum is first heated in a boiler to separate the smaller hydrocarbons with low boiling points from the larger hydrocarbons with high boiling points.石油先在一蒸發(fā)器內(nèi)加熱,從高沸點(diǎn)的大分子碳水化郃物中分離出低沸點(diǎn)的小分子碳水化郃物。Low boiling point of aldehydes have such as formaldehyde, aldehyde, high boiling point of aldehydes have furfural, d, e aldehyde, self aldehydes aldehydes, etc.低沸點(diǎn)的醛類有甲醛、乙醛等,高沸點(diǎn)的醛類有糠醛、丁醛、戊醛、己醛等。Non-azeotropic refrigerant mixtures R23/R22 is used as working fluid. The rectifying column is employed to separate high boiling component, low boiling component and lubricant.本文的循環(huán)採用非共沸混郃工質(zhì)R23/R22作制冷劑,利用精餾裝置分離高沸點(diǎn)、潤滑油與低沸點(diǎn)組分。原聲例句These are huge energies, Coulombic forces, high melting points and boiling points.這裡有巨大的能量,庫侖力,高熔點(diǎn)與高沸點(diǎn)。麻省理工公開課 - 固態(tài)化學(xué)導(dǎo)論課程節(jié)選So strong bonds means high melting points and boiling points.因此,如此強(qiáng)的化學(xué)鍵意味著更高的熔點(diǎn),和沸點(diǎn)。麻省理工公開課 - 固態(tài)化學(xué)導(dǎo)論課程節(jié)選Why do they have a high melting point and boiling point?爲(wèi)什麼會(huì)有高熔點(diǎn),和凝固點(diǎn)呢?麻省理工公開課 - 固態(tài)化學(xué)導(dǎo)論課程節(jié)選 返回 high boiling
