The equilibrium equation were established through to experimental data, the equilibrium line of crystallization is: X_ cc=exp[(T_c+1 753.8)/402.68], and the mother liquid equilibrium line is: X_m=exp[(T_c+690.0)/172.2].
Mass balance at SDS section in 1991/1992 was a weak positive balance year with a mass balance difference of 163 mm,altitude of equilibrium line was 140m,which was 20m lower than that of dynamic equilibrium line.
The authors recommend two analytical calculation methods: sectional calculation and curve fitness numerical integration for lower concentration absorbing system of which the phase equilibrium line is curve.
There is a complete stability region for liquid phase and no equilibrium line between Fe~(3+) and Fe~(2+) because of the simultaneous equilibrium between all metallic ions and solid species.
2. State equations along the vapor-liquid equilibrium line of ~3HeThermodynamic properties including vapor pressure, orthobaric density, latent heat, specific heat, enthalpy and entropy were extensively investigated along the vapor-liquid equilibrium line.
Mass balance at SDS section in 1991/1992 was a weak positive balance year with a mass balance difference of 163 mm,altitude of equilibrium line was 140m,which was 20m lower than that of dynamic equilibrium line.
Recently, a general concept that mass balance and its components versus altitude curves are stable have been widely accepted, so that the authors suggest, based on observations on many glaciers, that mass balance and its components at the steady state equilibrium line altitude ( ELA 0) equal their average values on a glacier respectively.
In this paper, the possible values of AAR of valley glaciers with various shapes in the steady state are estimated They are mainly governed by the altitudinal distribution of mass balance, shape factor and variation of surface slope of a glacier The relation between the altitudinal distribution of mass balance, shape factor of a glacial plan view and AAR of a valley glacier in the steady state is acquired The method of AAR for determining an ancient equilibrium line altitude is appropriate for a valley glacier
Based on field measured data of mass balance from small dome of Collins Ice Cap in 1991-1992 and meterological data of summer mean temperatures,annual precipitations from Frei Meterological Centre of Marsh Base nearby,the mass balance variations on small dome in 1971-1992 were calculated by the method of equilent mass balance at equilibrium line altitude. From the calculated results, we found that, the contributions of precipitation and temperature to mass balance were 68% and 32% respectively.
The authors of present paper deal with the implication of the equilibrium line altitude (ELAO) of glacier for environment and review the methods of its identification so far within China and abroad.
To determine the critical point on this line the explicit form of solutions of a system of homogeneous equations is considered and their relationship to the slope of the phase equilibrium line is established.
Precise pressure experiments in supercooled bcc 4He are carried out under cooling along an isochore near an equilibrium line of the bcc-hcp structural phase transition.
The internal relationship and external characteristics of Glacier No.l are analysed in the present paper on basis of the measured and interpolated data.It is found from the analysis that the glacial equilibrium line variation (rise and drop) not only indicates the increase and decrease of mass balance,but also reveals different feedback mechnisms of glacial shape and surface albedo with the positive feedback accompanying equilibrium line drop and the negative feedback accompanying th...
The average summer (from June to August)air temperature is 1℃lower and zero-equilibrium line 88 m lower in the 18 years after 1968 than that in the 11 years before 1968 in the middle part of Qilian Mountains. It was found from the mass balance reconstructed according to the air temperature and precipitation from 1957 to 1985 on the"July First" Glacier that the glacier was characterized by the negative mass balance state with a cumulative negative mass balance value of 232.9 × 104m and by the pos...
Using the meteorological data of the meteorological stations and hydrological stations in Tianshan Mountains, and the new data of the glacier inventory in Tianshan,the authors computed the mean summer (6-7) temperature at the typical altitudes, and estab-lishec the empiric formula calculatin the annual ablation (A) at the equilibrium line altitude (ELA): A = 0.78(T6-8 +9.0)3.09. The annual precipitation near ELAs in every ranges of Tianshan Mountains was calculated by extropolation. The results ...
