The paper introduces the latest method how to gain chemical compositions in crystalline melt inclusion . Based on the previous research data, we review and discuss some important factors which may influence on the compositions of melt inclusions and the volatiles contents of H 2O,CO 2,Cl,F, S and its evolution trend in various magmatic melt.
This paper introduces the network structure of CDMA2000 1X system and two methods of access to CDMA2000 1X packet data network. Then some key technologies of CDMA2000 1X are discussed and its evolution trend is given.
In the attractive, future, digital life of mankind, which is saw by both“Ubiquitous Computing”advocated by IBM and “Seamless Computing”advocated by Microsoft respectively, the network is playing an important role,and making a general survey of the evolution trend of the network, it just cater tothe needing of such bright prospect.
Based on the evolution trend and service features of B3G, a three-dimension service model is proposed, including dimensions of service supporting scope, service capability definition and adaptive feature element. Accordingly, a hierarchical service architecture for B3G is introduced.
It also seemsthat the value of the clay-weighting coefficient affects the evolution trend: permeability mayincrease when the porosity decreases (and vice versa).
A common feature of element distribution patterns is the small systematic change in the early lithologies, but a distinct evolution trend in the late quartz-bearing rocks.
From the cases we studied we cannot establish for P1 either a clear radial evolution trend, or a solar-wind-speed or stream-structure dependence or a systematic anisotropy for both the flow velocity and magnetic field component fluctuations.
The liquid evolution trend depends strongly on the initial compositions.
On the unheated substrates, the phase-evolution trend was found to be different for % N2 above 10.
