  • [Mechanism] ph
Examples:
1. 许多生物化学过程只能在人体内部存在的天然缓冲溶液--例如血液、眼泪和精液--所维持的特定酸碱值下进行。
"Biological fluids such as Blood, tears, and semen have natural Buffers to maintain them at the pH required for their proper function. See also law of mass action. "
2. 缓冲溶液 化学术语。通常指含有一种微酸和与之结合的一种微碱或盐,并能维持酸碱值基本恒定的溶液。
"Buffer Solution usually containing a weak acid and its conjugate weak Base, or a salt, of such a composition that the pH is held constant within a certain range."
3. 加入酸或碱会使它们的浓度发生相应的改变,但它们的比值以及酸碱值仍接近原有数值。不同的缓冲溶液可制得不同的酸碱值。一般常用的缓冲溶液有磷酸、柠檬酸或硼酸以及它们的盐。
"Relatively small additions of acid or base will change the concentration of the two species, but their ratio, and hence the pH, will not change much. Different buffers are useful in different pH ranges; they include phosphoric acid, citric acid, and boric acid, each with their salts."
4. 人血浆为草黄色,其功能有作为血液运输的介质、帮助维持血压、分配身体热能和保持血液和身体的酸碱值平衡。
"This straw-coloured fluid serves as the Blood's transport medium, helps maintain Blood pressure, distributes Body heat, and maintains the pH Balance in the Bloodstream and Body."
5. 酸碱值: 溶液中酸(和碱)的强度的定量量度,其定义为用克分子/升表示的氢离子(H+)浓度的自然对数的负数:pH = -log10〔H+〕。
"pH Quantitative measure of the strength of the acidity or alkalinity (see acid, Base) of a solution. It is defined as the negative common logarithm of the concentration of hydrogen ions [H+] in moles/litre: pH = -log10 [H+]."
6. 水溶性酸碱值
Acid alkali soluble in water
7. 用酸碱度计量度水样本的酸碱值。用氯化钠折光仪量度样本的氯化钠含量。
Measure pH of the seawater by a pH meter. Measure salinity by a refractometer.
8. 正常酸碱值幅度
Normal pH range
9. 酸碱值〔水质指标〕
PH [water quality objective]
10. 酸碱值调正
PH value correction
