1.In this stage sampling areas and frequency decreased as compared to prior phases. 2. Phase III represents the water system exhibits dependable under Manage attainment above these kinds of quite a while period & Phase III usually runs for a single year after the satisfactory completion of stage II.

使用pH试纸，pH试纸有广泛试纸和精密试纸，用玻棒沾一点待测溶液到试纸上，然后根据试纸颜色对照比色卡也可以得到溶液的pH。上方表格就相当于比色卡。Adverse physiologic effects of saved blood is negligible within the absence of a past compromise with the Pt's–recipient's positionpH試紙及pH指示劑難以測試有顏色的溶液，因為溶液的顏色會干擾結果的顏色，所以不能使用pH試紙及pH指示劑測試有顏色的溶液。The pH is
