比水量(specific water flow) 连铸|轧钢机二冷区单位时间内消耗的总水量与单位时间内通过二冷区铸坯质量的比值，以L/kg为单位。它是连铸|轧钢二次冷却喷水强度的指标。比水量大小会影响铸坯在二冷区表面温度分布、铸坯裂纹和偏析。此值主要决定于钢种，一般为0．5～1．5L/kg。低碳钢或裂纹不敏感的钢种取高值；高碳钢、高锰钢、合金钢或对裂纹敏感的钢取低值。

回归分析表明偏析指数与二冷比水量的相关性最大，而与钢水过热度的相关性不强。
Regressive analysis shows segregation index has maximal relationship with water ratio in secondary cooling, and has low relationship with superheat degree of steel.
研究了不同拉速、过热度及二冷比水量对铸坯表面中心和角部温度及铸坯凝固终点位置的影响。

注意“净值”这一词：测量地下水渗入并且渗出湖水的实际水量比仅仅推断出它们的差异要复杂得多。
Note the word "net" measuring the actual amounts of groundwater seepage into the lake and out of the lake is a much more complicated matter than merely inferring their difference.
