So two main problems was taken out in the process of production, which are measuring the mass of aluminum in one bath accurately and controlling the precision exactly.
因此对于铝电解出铝操作而言有两个问题亟待解决，单槽出铝量的准确计量和单槽出铝精度的自动控制。

Process conditions, various color fastness, production cycle, as well as the cost were compared between the one bathtwo step process and twobathtwo step process.
对涤棉一浴二步法和二浴二步法工艺条件、染色牢度、生产时间及成本等进行了比较。
