基本解释

Slow cooling mold can effectively reduce the unevenness of initially solidified shell of hypoperitectic steel;
缓冷结晶器可有效地改善低碳钢初期凝固坯壳的不均一性；
Specimens prepared by polishing and etching in a weak solution of nitric acid and alcohol reveal the lamellar structure of alternating plates that forms on slow cooling.
通过打磨并在弱硝酸酒精溶液中蚀刻制备的样本显示出由缓慢冷却形成的交互层状的薄片结构。
The results show that both the slow cooling rate to control ferrite transformation and the rapid cooling rate to control bainite transformation affect the microstructure of TRIP steel obviously.
结果表明，热变形后控制铁素体相变的慢速冷却的速度及控制贝氏体相变的快速冷却的速度对最终组织的组成影响较大；

In general, there was a slow cooling of 0.6 degrees Celsius over the earlier period.
