竞争离子 competing ions
离子竞争反应 competitive reaction of ions
在碱性下阳离子竞争趋势因膜污染严重而不再明显。此外，操作压差过大不仅分离效率下降而且膜污染加剧。温度升高有利于脱盐而不利于纯化。
Moreover, the over high pressure not only reduce operation efficiency, but also cause the membrane fouling serious. The high temperature is favorable to desalination and unfavorable to purification.
液晶显示器与等离子板之间的竞争也没有结束。
Nor does the rivalry between LCD and plasma panels end there.
击败市场竞争者的同时，也给已经败在液晶显示技术之下的等离子技术带来一点转机。
Beating rivals to the market could also provide a boost for its plasma technology, which has been losing out to liquid-crystal displays.
