The acidity or acid/ alkaline balance of the blood is measured by pH, the potential of Hydrogen, see ( http:// en. wikipedia. org/ wiki/ PH) and is a very important marker for good health. 人体血液的酸碱度由PH决定,酸碱度是衡量健康水平的一个重要指标。
A good level of acidity is essential for balance, the refreshing taste of crisp whites, and ageing potential in all wines. 良好水准的酸度对平衡以及白葡萄酒中爽脆的口感至关重要,还有影响到所有葡萄酒的陈酿潜力。
The acidity constant ( pATa) of a metabolic uncoupler highly influenced its effectiveness in sludge reduction, i.e. metabolic uncoupler with a lower pKa value has a higher potential to reduce sludge production which confirmed the theoretical analysis that uncoupler weaken the proton motive potential producing ATP. 各种代谢解偶联剂效果的差异与其酸性大小有关,pKα值越低,污泥的减量化效果越好,这证实了解偶联剂所造成的产生ATP质子动力势(pmf)弱化的理论分析。
The influence on inner cell calcium, the acidity in cell plasma and the mitochondrial membrane potential after long term activation of opioid receptor; 阿片受体长期激活对细胞内钙离子、细胞浆酸碱度以及线粒体膜电势的影响;
The behaviour of alloy 13 prefilmed specimen in NP preoxidation solution is different from 18-8 S. S. and Incoloy 800. In the low acidity, the corrosion potential moves toward positive direction as the acidity becomes high. 试验中发现新13号合金预生膜试样在NP氧化预处理剂中不同于一般合金材料(如18-8不锈钢,Incoloy800合金),在低酸度区,腐蚀电位随酸度升高向正方向移动的特性。
Because of the high acidity, low nutrients content, aluminum toxicity and potential heavy metals pollution, oil shale waste slag has negative effects on the normal growth of plants. 油页岩废渣因酸度高,养分含量低,并存在一定程度的铝毒和重金属污染等,使得植物很难在其中正常生长发育。
The acidity constant ( pK_a) of a metabolic uncoupler highly influenced its effectiveness in sludge production, i.e. metabolic uncoupler with a lower pK_a value has a higher potential to reduce sludge production. 解偶联剂的酸性常数pKa很大程度上影响了其在减少污泥产率方面的效果,即pKa值越低的解偶联剂对减少污泥产率的效果越好。
There are three forms of acidity in acid sulfate soils: water-soluble acidity, retained acidity and sulfide-derived potential acidity. 酸性硫酸盐土的酸度可分为水溶性酸度、吸持性酸度和金属硫化物起源潜在酸度等3种类型。
The character of nitric's molecular structure determines that it can separate completely in solution, so the nitric has strong acidity; according to its standard potential electrode, the teacher and students can judge it can be oxidized. 硝酸的分子结构特征,决定了硝酸在水溶液中能完全电离,所以硝酸具有强酸性,根据硝酸的标准电极电势,师生可推断出硝酸又具有氧化性。
The effects of the acidity and concentration of electrolytes, accumulation potential, accumulation time and scan rate on peak current of cobalt were studied to acquire optimum conditions. 研究了介质的PH值、介质的浓度、富集电位、富集时间及扫描速度等因素对峰电流的影响,获得较为优化的测试条件。
