The lower the pH, the higher the acidity; highly acidic foods and beverages include diet sodas (2.9 to 3.7), strawberries (3.5) and barbecue sauce (3.7).
pH值越低，酸性越高；无糖苏打饮料（pH2.9-3.7）、草莓（pH3.5）以及烧烤调味酱（pH3.7）等食物饮料均属高酸食品。
The plants and animals that have evolved over time to thrive in slightly alkaline surface waters-their pH is around 8.3-are now having to adapt to a 30% increase in the acidity of their surroundings.
在漫长的进化过程中，海洋动植物已经习惯了海面的弱碱性——PH值大约为8.3，但现在它们不得不去适应所处环境酸度30%的下降。
The results show a bleak future for Marine life as ocean acidity rises, and suggest that similar lowering of ocean pH levels may have been responsible for massive extinctions in the past.
结果表明，由于海洋酸度上升，海洋生物的未来暗淡，认为类似持续降低的海洋pH值可能导致了过去大规模物种的灭绝。
Measurements of the pH of the Coke before and after the experiments showed that its acidity did not change, ruling out the idea that a simple acid-base reaction drives the fountains.
经过测量反应前和反应后实验前后的可乐pH值发现前后酸性没有发生变化，排除了简单的碳酸反应导致这喷泉影响的想法。
Test the gastric acid secretion, PH, total gastric acidity value, total pepsin activity of change after irrigation.
测定给药后大鼠胃液分泌量、胃酸ph、胃液总酸度值、胃蛋白酶活性的变化。
The magnitude of the thermal process is a function of product PH or acidity.
产品的pH值或酸度是热处理强度的函数。
The pH scale, the standard measurement of acidity, was developed in Carlsberg's laboratories in 1909.
1909年，嘉士伯啤酒的酸碱值、酸度都在嘉士伯的实验室中得以测量。
The degree of acidity or alkalinity of any solution, then, can be most conveniently expressed by the PH system.
因此 ，任何溶液的酸碱度都可以用PH体系来表示。采用这种方法极为方便。
Production in the rising trend, with ph dilute sulphuric acid adjust ph value and to fully mix, prevent local high acidity and cause brightener exhalation.
生产中pH朝上升趋势，用稀硫酸调pH值并要充分搅拌，防止局部酸度高而导致光亮剂析出。
Production in the rising trend, with ph dilute sulphuric acid adjust ph value and to fully mix, prevent local high acidity and cause brightener exhalation.
生产中pH朝上升趋势，用稀硫酸调pH值并要充分搅拌，防止局部酸度高而导致光亮剂析出。
