The establishment of spectrum function involves comprehensive analysis problems of interdisciplinary mass geological data, for example, the earth science data, physics data, chemistry data, remote sensing data, and so on [2,3].
This article studies this issue, and puts forward an encoding method of geological spatial objects based on α tree structure.
In Figure1, In order to make a level of "project - category - reaction" expansion and extension, we use a multi-level, multi node of tree structure, so we call it “α tree structure” that is, The depth of the tree is α.
The encoding method based on α tree structure is applied to the gold mineral unit and element variable, Statistical models are built by using the quantification theory IV.
The scale chart of 21 mineral unit Conclusions 1 Encoding the multi hierarchy geological qualitative variables with α tree structure, it is a good quantitative method. 2 α tree structure and the quantification theory IV combined to predict mineral resources, have a higher success rate.

The atomic and electronic structure of 4H-SiC(1 1 02) surfaces were investigated using scanning tunneling microscopy (STM), low-energy electron diffraction (LEED) and photoemission (PES).
It should be emphasized that the model proposed here should be only viewed as a plausible starting point for a quantitative structure determination by crystallography or total energy calculations.
The electronic structure of this SiC(1 1 02)-c(2×2) phase is experimentally determined by angle resolved PES studies of the valence band revealing four surface states.

The energy barriers and the reaction energies were evaluated with the accurate model chemistry method at G3(MP2) level after a non-dynamical electronic correlation detection.
Frequency analyses at the same level of theory were proceeded with the optimized geometries to determine the harmonic vibrational frequencies, the zero-point energies (ZPE) (scaled by 0.9631) and to confirm the structure being a stationary species or a transition state.

This mainly because a tight transition state structure is not favored by entropic effects at high temperatures.

Anodised mesoporous TiO2 films have been characterized by Raman spectroscopy, which indicates the presence of well-defined peaks related to anatase structure.
After anodisation, mesoporous TiO2 films were heated up in an oven in order to investigate the relationship between heating temperature and TiO2 phase structures.
