A numerical measure of the acidity or alkalinity of a solution, usually measured on a scale of 0 to 14. Neutral solutions have a pH of 7, acidic solutions have a pH lower than 7, and alkaline solutions have a pH higher than 7. ...
The pH scale is a measure of acidity/alkalinity and provides information about how substances tend to act in aqueous solutions. All living processes occur in an ideal pH range. Buffers act together to keep the pH within a certain range, based off the release or absorption of hydrogen ions.Ch...
The pH of a third buffer solution of intermediate pH read off on the scale must not differ by more than 0.05 pH unit from the value corresponding to this solution. pH值为上述两个缓冲液之间的第三个缓冲液pH读数不得超过相应pH值的0.05个单位。 Immerse the electrodes in the solution to be exa...

Nitrous oxide (N2O) is a climate-active gas with emissions predicted to increase due to agricultural intensification. Microbial reduction of N2O to dinitrogen (N2) is the major consumption process but microbial N2O reduction under acidic conditions is co
An assessment of the spatial scale of local adaptation in brown trout (Salmo trutta L.): footprints of selection at microsatellite DNA loci. Local adaptation is considered a paradigm in studies of salmonid fish populations. Yet, little is known about the geographical scale of local adaptation. ...

Studies on the decomposition/oxidation of nitrite at differentpH values and aeration flow rates were investigated using abench-scale batch reactor. The conditions were pH 2.85, 3.50,5.80, 7.0, and 16, and with or without aeration at airflowrates of 50, 2.25, and 3.25 L min<sup>-1</sup>...
4.2. Large scale reactors Compound parabolic collectors (CPC) consist of transparent tubes that can be made from a number of materials but typically borosilicate glass [230] that will be filled with the water to be treated. The tubes sit over a series of mirrors that are used to concentrate...
[5] utilized the graph attention network and MHA to update the feature representations of nodes. Zhao et al. [6] proposed a GCN-based ABSC model, effectively capturing the sentiment dependencies among multiple aspects in a sentence. Since the emergence of large-scale, pre-trained models, such...
