求翻译：淬火油的功能是将赤热的钢铁弹簧的热量迅速带走，使之降至马氏体转变温度以下，获得高硬度的马氏体组织和硬化层深度，同时亦要兼顾减少弹簧的变形和防止开裂。因此，淬火油的基本特性就是“冷却特性”，其特点就是高温阶段的冷却速度较快；而在低温阶段冷却速度较慢，这一特性很适合弹簧制品的淬火要求。是什么意思？

The function of the quenching oil will take away the heat of red hot steel spring quickly dropped below the martensitic transformation temperature, high hardness of martensite and hardening layer depth, but also to take into account to reduce the deformation of the spring and to prevent cracking.

The quenching oil function is carries off rapidly the red hot steel and iron spring quantity of heat, causes it to fall to the martensite transition temperature below, obtains the high degree of hardness the martensite organization and the hardened level depth, simultaneously also must give dual att
