In the end the relationship of steel grades, mould length, drawing speed and sectional dimensions of the billet with mould taper and solidification and contraction coefficient has been discussed.
最后分别讨论了钢种、结晶器长度、拉坯速度、铸坯断面尺寸与结晶器锥度、凝固收缩系数的关系。
Temperature contraction coefficient is a parameter for material expansion and contract property when temperature becomes high ot low.
温度收缩系数是反映材料热胀冷缩特性的参数,贫砼基层材料的温缩特性又直接影响到温度应力。
Because of the always-outdated statistical data in the calculation of GDP contraction coefficient currently, we still adopt CPI indicators to measure the degree of inflation.
由于GDP紧缩系数的计算还存在统计数据滞后的问题,因此,我国通货膨胀的衡量目前仍采用CPI指标。
Last, the temperature contraction coefficient and dry shrinkage coefficient of porous concrete are advanced.
