ecf怎么记

forasmuch, the higher the intensity of hot water pre-extraction, the lower the negative effect of unit saccharides yield in extracts on subsequent kraft pulping and ecf bleaching.

所以，热水预抽提的强度更高，单位糖组分得率对后续KP法制浆和ECF漂白所造成的不利影响越低。

The results indicate that the hydrolysis is a pseudo-first order reaction with faster rate, good selectivity in removing HexA and could be used for ECF and TCF bleaching sequences.

结果表明该水解反应为一反应速度较快的拟一级反应。此外，该水解反应的选择性较高，可望应用在无元素氯（ECF）和全无氯（TCF）漂白技术中。

ECF bleaching of the modified kraft pulp ( MK) and conventional kraft pulp ( CK) of Pinus elliottii was carried out in this study.

对南方湿地松改良硫酸盐法浆（MK浆）和常规硫酸盐法浆（CK浆）进行了ECF漂白的研究。
