Solubility of dye commodities is the reason for restricting the dye-uptake enhancement and the low bath ratio process popularization. 染料商品化中的染料溶解性一直制约着上染率的提高和小浴比染色新工艺的推广。
Meanwhile, the gas-liquid ratio for foam drilling or gas-filled underbalanced drilling in normal pressure formations is analyzed. 同时分析了在常压地层进行泡沫或充气欠平衡压力钻井时所需的气液比。
