Experiments show that if NaCl is put into distilled water, its salinity is up to 80 000 mg/kg, increments of density and water cut are 0. 044 g/cm3 and 2.4%,respectively.
According to the sampling tests, the total degree of mineralization of the river water varies from (256.12mg/L) to (413.74mg/L), the total hardness varies from (3.37me/L) to (7.16me/L), and the total alkalinity varies from (2.62me/L) to (4.25me/L).
As a whole, the degree of mineralization had a ascend trend, there was a biggish value in 1988, then the trend changed to smooth, and now the value is some bigger.
However, from upper stream to downstream, the degree of mineralization and the total rigidity also the main ions contained increase gradually, thus the water quality becomes badly gradually, and all of this reflects the chemistry characteristics which are dominated by the evaporation and concentration.
degree of mineralization is an important index in the groundwater analysis In environmental monitoring,the conventional method to determine the degree of mineralization for groundwater is weighting method Through determining the Luoyang groundwater conductivity,analyzing the relationships between conductivity and mineralization rate,and establishing the quantitative relations between conductivity and mineralization rate by using regression equations We find out the indirect method for determining mineralization rate by conductivity method The advantages for conductivity method are speedy,economical and accurate
daily runoff. The water quality of Daquan River belongs to weak alkaline slight saline water and hard water; pH is 7.3~8.1, the mineralization degree is 1500mg/L~2300mg/L, the total rigidity degree is 25 ~33H°, and the annual change of the water quality is not very obvious.
The factors of rainwater and tide can make Cl-content, mineralization degree and hardness of groundwater change, which reflects influence of groundwater.
As uncovered by geothermal drilling, temperature of geothermal water is 57℃, hydrochemical type is SO_4Ca, and mineralization degree is 3~6g/L. It is geothermal mineral water with medical value.
euphratica leaves exhibited a higher capacity to exclude salt in a longer period of increasing salinity, thus limited salt-induced lipid peroxide and MP, which contributed to membrane integrity maintenance and salt tolerance of P.
The results of seed germination under various environmental stresses and investigation of soil conditions indicate that well-aerated, slightly acidic soils with low salinity are suitable for the growth of S.
The decomposition study showed that A450 exhibited significantly higher decomposition rate, mineralization rates of N, P and K as well as much shorter N and P net immobilization periods.
Bone quality includes parameters such as trabecular and cortical microarchitecture, morphology, bone turnover, degree of mineralization of the bone matrix, and significantly, the amount of microdamage present in the bone.
In the course of water resources transformation and utilization, the chemical composition and degree of mineralization are influenced by both geographic conditions and human activities.
In this paper the semivariogram of geostatistics, in combination with GIS, was used to quantitatively study the spatial variation characteristics of groundwater table depth and mineralization degree and their relation to the landuse changes.
F test of the used spherical model reached a very significant level, and the theoretical model can well reflect the spatial structural characteristics of groundwater table depth and mineralization degree and achieve an ideal result.
