3) concrete at early ages
早期混凝土
1.
Because early ages of concrete setting and hardening are critical stages of concrete influencing and even controlling cracking resistance and other performances of concrete at later ages, emphases are put on those research situations about the shrinkage and cracking of concrete at early ages, .
由于混凝土凝结硬化的早期是影响并控制混凝土抗裂性和后期性能的关键阶段,因此重点介绍了早期混凝土收缩、强度、弹性模量、徐变等的动态发展过程及这一过程对混凝土开裂趋势和抗裂性能的影响等方面的研究情况。
5) initial solidification
初期凝固
1.
The initial solidification phenomena of low carbon steel,which solidifies with a hypoperitectic reaction in the continuous casting,have been modeled.
为了模拟连铸过程中具有亚包晶反应的低碳钢的初期凝固现象,利用浸渍实验,测量了铸坯的二次树枝晶间距;利用有限元的一维传热汁算,求得冷却速度与二次树枝晶间距的关系式;探讨了传热阻力等参数对铸坯的冷却速度、凝固不均一度的影响。
2.
The temperature fields and stress fields of initial solidification shell in the mould of smooth and groove were calculated,the difference between the tWo condition was analyzed and effect to dritial solidiflcation process caused by model of grooves was stUdied .
以初期凝固坯壳为研究对象，在结晶器内壁纵向划分沟槽，建立数学模型，计算划分沟槽与不划分沟槽结晶器内铸坯的温度场和应力场，研究沟槽内壁结晶器对铸坯初期凝固过程的影响。
6) premature set
先期凝固
补充资料：早期凝固
分子式：
CAS号：
性质：指胶乳在进厂加工前由于保存措施不力已发生的鲜胶乳凝固现象。通常需采取强化保存措施以防止胶乳的早期凝固。
