At pH 1.61 (the lowest pH of the influent liquor used in the case) the concentrations of free protons and HSO4- were calculated to be 25 and 14 mM respectively, i.e. sufficient for the reduction of ~20 mM sulfate.
In the case of the synthetic raffinate, sulfate concentrations in mine water at the site itself are well in excess of those used in the current experiments, so synthetic water used in the experiment was always acidified with sulfuric, rather than hydrochloric, acid, Data (Fig 2) show that more sulfate (up to 35 mM in total) was removed than with the synthetic Nochten water, though the efficiency of this in terms of electron donor usage was far lower.

The method in spatial is getting the information of the original image, a denoising algorithm based on pixel gray value of direct data operation, to obtain the desired results.Transform domain denoising is a kind of transformation to transform a class of information of image in spatial domain, then the transformed information processing, finally the processed information through the inverse transform backinto the spatial, the image space domain to achieve the purpose of removing noise.
In the spatial domain filtering algorithm in the past, the direct use of variance of noise image gray median or mean value as a threshold, smoothing the details of the image, reduction image quality.

However, SiO2 in slag would suppress reduction of MgO, CaO in slag by [Al]s in steel, which is not beneficial for transformation of the product of Al-deoxidation.

The Au/P25 catalysts were prepared by deposition-precipitation with DBD plasma reduction method (denoted as Au/P25-P) and a conventional thermal impregnation method (denoted as Au/P25-H), respectively.
All data were acquired after 30 min reaction time to allow the attainment of steady state.

Introduction
The negative ions in the air has a positive effect on the growth of the body and preventing disease: (1)Aoion can improve the lung organ function and respiratory villi cleaning efficiency; (2)Aoion can reduce blood pressure and enhance myocardial function; (3)Strong oxidation-reduction.
In a certain volume test chamber, the number of negative air ion which are excited in the unit volume of space is tested when the sample are mutual rubbed which is under the specified conditions of GB/T6529, and then the negative air ion passed through the automatic inlet of test equipment, and at last the data is readed by computer.

The instrumented falling weight impact (IFWI) tests have been performed on a Ceast Fractovis
IFWI tester equipped with a Ceast DAS 8000 data acquisition system according to EN ISO 6603-2.
With increasing irradiation doses, the ILSS of the composite has increased by 11% to the dose of 50 kGy, after that a slight decrease could be observed, which can lead to the assumption, that between 50 and 100 kGy the dominance of the beneficial effect of the increase in crosslinking density has been changed to the negative effect of the reduction of chain segment lengths of the epoxy matrix.
