contraction coefficient

基本解释

Last, the temperature contraction coefficient and dry shrinkage coefficient of porous concrete are advanced.
得出多孔混凝土的溫縮系數和乾縮系數。
With increasing of the valve opening the range of the recirculation zone length and the contraction coefficient was reduced continuously;
廻流區變化幅度與收縮系數變化幅度隨開度的增大不斷縮小；
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.
最後分別討論了鋼種、結晶器長度、拉坯速度、鑄坯斷麪尺寸與結晶器錐度、凝固收縮系數的關系。
