Although the EIT has an
inherent advantage of high speed data acquisition, the poor spatial resolution of the reconstructed
image remains as challenging problem to be solved.
This results in reduction of the computational burden.

The SG can be used: 1) to generate electricity; 2) as city gas; 3) to produce direct reduction iron; 4) to produce chemical or energy product, such as carbinol and hydrogen.
Based on the data above, the autarky rate of electricity in each factory is obtained (table 4).

Poor surface quality can increase surface irregular
roughness and cause reduced thermal and mechanical fatigue life and reduction in impact strength,
leading to premature die failure.
These data are all averages of three experimental specimens in order to eliminate the random measure errors.

Cement is the main cementitious material of concrete, the hydration process is accompanied by the formation and breakthrough of potential barriers, about 20% of the cement failes to fully hydrated, only Play a role of filling, the electronegativity of alcohol amines groups in concrete synergist can enhance electrostatic repulsion of particles surfaces, the cement slurry dispersion improves[7], making cement paste to set data package to improve.
(3) Due to the reduction of cement dosage, the compensation of early cement hydration products on concrete shrinkage weakens, which results in makes early shrinkage of chip concrete increasing, but by stimulating the activity of the mineral admixtures, concrete synergist can promote gelled material hydration and compensate parts of shrinkage, make concrete contraction narrow and tends to be stable
