contraction coefficient

基本解释

Last, the temperature contraction coefficient and dry shrinkage coefficient of porous concrete are advanced.
得出多孔混凝土的温缩系数和干缩系数。
With increasing of the valve opening the range of the recirculation zone length and the contraction coefficient was reduced continuously;
回流区变化幅度与收缩系数变化幅度随开度的增大不断缩小；
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。
