Results The mean concentration of 226 Ra, natural uranium,natural thorium, 40 K,and radon in mineral water were 68 6 mBq·L -1 ,2 14 μg·L -1 、0 65 μg·L -1 ,0 199 Bq·L -1 and 209 8 Bq·L -1 , respectively.
A fuzzy neural network for identifying 11 kinds of mineral waters is developed based on an entropy based clustering method Partitioning fuzzy input space and extracting fuzzy IF THEN rules are implemented employing the clustering method and the Gradient Descent algorithm is used for optimizing system parameters, so that the system has good interpretability and learning capability Experimental results show that the system is feasible and effective for identifying 11 kinds of mineral waters by its taste signals
Isotopic ages of mineral waters in Shiqian area are calculated by 8methods, based on 14C, 13C and tritium isotopic values and chemical analysis of relative comPOsitions.
Objective To determine the geological characteristics, the distribution characteristics and the development of mineral springs in Lintong sanatorium district as well as the main physical and chemical properties and types of various mineral water and to provide the scientific base for the further development of the resources of the mineral springs in this sanatorium district.
Methods The overall data of the resources of the mineral springs for medical use were summarized with the investigation of the resources of the mineral springs in Lintong sanatorium district and with the results of the water quality monitoring for past years.
The natural mineral springs are obviously controlled by fault, fold and structural alteration zone and the water circulates along deep fracture zone and moves along interlayer faults or tectonic fissures, finally, wells out under an artesian condition.
The mineral springs are outcroppedalong the regional deep fault zones and its adjacent area,the intersection area of faults or thesecond-order faults near the main one,the weak zone of the conjugated parts of uplift and de-pression of Ⅳ order structural unit and the contact zone of magmatic rocks and their wallrocks.
The mineral water in Xinzhai is a calcium sodium bicarbonate kind of radon bearing mineral water with low sodium and degree of mineralization, which is from deeper, structural feasures in granite.
Based on theoretical analysis, using the “Sinoiodine iodine bearing mineral water” as an example, the paper discusses the content limit stiputated in the National Standards of drinking natural mineral water.
Gas-phase pyrolytic synthesis of carbon to give multilayer carbon nanotubes on Ni catalysts supported by NaCl and K2SO4 mineral water-soluble substrates was studied.
The operation of the device showed that the device ensures the sufficient functional possibilities and the accuracy necessary for hydrodynamic investigations of mineral water wells.
Nonsulfur photosynthetic purple bacteria isolated from the Dzhermuk mineral springs (Armenia) were grown on sugar-containing media and found to be capable of synthesizing L(+)-lactic acid.
When using the MFE method for prospecting, the relationship between the ascending mineral springs and the four directions of structural faults was discovered.
The deerite-bearing mineral association includes (1) deerite + riebeckite + stilpnomelane + ilvaite + magnetite + quartz and (2) deerite + stilpnomelane + magnetite +quartz based on the investigation under microscope.
Microanalytical studies of basement rocks below the Athabasca sandstone basin indicate that monazite is the dominant uranium-bearing mineral in the study area.
Chonghua Yuntal mountain mineral spring is located in the Jiulibu garden and it comes from deep underground water. The spring has a flow of 300 tons a day. Its composition, flow rate and temperature are very stable even in different seasons and weathers. The main components of the spring water are radon and carbonates. It also contains 16 trace elements (Fe, F, Zn, Br, Cu, V,Se,I, Ag, Al,Ni,Mo, Cr, Li, Mn, Co ) and 12 rare earth elements (Th, La, Yb, Dy, Ce, Nb, Ta, Zr, Ba, Sr, Sm, Nd ) , which are necessar...
The article describes the rehabilitative effects of AS patients treated by medical exercise under mineral water once a day. These cases were treated 37 times on an average. The therapeutic effect was remarkable; cured 81.6% (408 cases), alleviated, 15% (75 cases). The total effective rate was 96.6%. The functional disturbances of spine and extremities were obviously improved, including the flex and extension in cervical, thoracic or lumbar, knee down, raised arms, vital capacity, respiration difference and ...
The west rocky spring mineral water produced byDabu mineral water Co., Guangdong was examined by mean's of salmonella muiagenic?city test. Results indicated that the mneral water tested was not mutagenic. The revertants induced by 3, 4-benzo(a) pyrene (with TA100), 4-nitroquinoline?N-oxide (with TA98, TA100), mitomycinc (with TA102) and ultraviolet ray (with TA102) were significantly decreased when the mineral water was added to the medium.
