The carbon content of steel will determine its quality. The purity of drugs will determine their efficacy.
钢铁中碳的含量决定其质量，药物的纯度决定其疗效。
The non equilibrium carbon potential is defined as the carbon content of steel when the net carbon production rate at surface of steel vanishes.
非平衡气氛的碳势定义为：当渗碳反应在钢表面净产生的碳为零时碳钢表面的含碳量。
Therefore need for low thermal conductivity of ladle lining developed a method of refractory materials, the material is heat preservation and not to increase the carbon content of steel.
