本文在加热炉内钢坯加热过程数学模型的基础上，首次提出了一种以钢坯焓增过程积分值为目标函数求取加热炉最优炉温制度的方法。

In this paper, a new method to get the optimal furnace temperature of reheating furnace is brought up for the first time on the basis of the mathematical model of continuous reheating furnace.

我们发现自由焓的变化,为负92千焦，negative，92，kiloJoules。,熵增dS是负198焦耳每开尔文。

Well, here we get, we find that delta H is dH Delta S is negative 198 joules per Kelvin.

结果表明，增韧剂的加入使尼龙1212更容易结晶，结晶速度增大，结晶温度提高，熔融热焓降低；

Results indicate that crystallization of nylon 1212 become easy and crystalline velocity and degree increase, and the heat enthalpy decreases after the addition of the toughening agent.
