pH scale

同根派生

Despite this diversity and the fact that certain organisms can grow at extremes of the pH scale, generalities can be made.
縱然有差異而事實上有些生物是可以在極端的酸堿度范圍上生長，仍可以得到一些歸納結果。
A measure of the acidity or alkalinity of a solution, numerically equal to7for neutral solutions, increasing with increasing alkalinity and decreasing with increasing acidity.The pH scale commonly in use ranges from0to14.
酸堿度溶液酸性或堿性的度量，數(shù)值等于7的為中性溶液，數(shù)值增大表示堿性增大，數(shù)值減小表示酸性的增大。ph值范圍一般在0到14之間

That word is spelt with a PH, not an F.
那個字里的f音拼作PH而不是F。
The next year the work went ahead on a large scale.
第二年這項工作就大規(guī)模進行了。
