edta-na 中文意思是什麼

edta-na 解釋

The enzyme activity could be completely inhibited by pmsf and dfp, and partially inhibited by pepstatin a, edta and egta. leupeptin, benzamidine and hydrochloride aprotin had no influence on the dhap activity. ca2 *, mg2 + and na * could slightly increase, but cu2 + and zn2 + slightly inhibited protease activity

此結果表明， dhap為一種絲氨酸蛋白酶，其酶活性的發揮需要某些金屬離子的參與，如na + ， c擴+ ， m擴+等金屬離子能提高dhap的活性，但c了+與z矛十能抑制dhap的部分活性。
Integrating the dissolving experiments of na2edta and na4edta and the orthogonal experiments, we can conclude that the dissolving property of na ^ edta is relatively more stable and higher than that of na2edta in this experiment. and, the conclusion can be made that for the caso4 scale in membrane na4edta has the best cleaning effect and the optimum condition is ph = 11, operating pressure = 0. 1mpa and concentration = 4 % wt

在綜合考慮乙二胺四乙酸二鈉和乙二胺四乙酸四鈉對硫酸鈣的溶解性實驗及正交實驗，和最後對污染膜清洗的正交實驗可以看出，盡管最優工程選擇中nazedta清洗后膜的相對恢復率略高於na4ed飛』 a ，但其要求條件相對苛刻，從溶解性實驗也可看出， na4edrla對硫酸鈣的溶解相對穩定，溶解率高。
