The temperature flied distribution and deformation in the mould of thin slab were calculated, moreover, the regularity of shell growth and shrinkage was obtained.

计算出薄板坯在结晶器内温度场分布和变形，在此基础上得到了坯壳生长、收缩的规律。

The change of the components leads to high temperature stress, as well as remarkable shrinkage and deformation; also, its characteristics induce friability and fissility of concrete.

现代混凝土组分的变化导致了温度应力高、收缩变形大，早强和高强也引发了混凝土的早裂和高脆性。
