In this way, the parameters could be adaptive with structure without any complicated manual setting which is specific to controller data.
The analysis on temperature control of glass furnace The batch goes into furnace through dog house and becomes melting glass after complicated physical chemistry reactions under high temperature.
That is to say, there are different physical chemistry reactions and temperature requirement in different phases.
So, it is necessary to set up melting temperature gradient curve in accordance with requirement of physical chemistry reactions, which is along the longitudinal direction of melting tank[4].

Based on computational chemistry, we conducted computational simulation of Sini Decoction in treating coronary heart disease to reveal the mode of action between small molecules and the targets associated with coronary heart disease.
We can predict the activity of the chemical constituents with virtual screening techniques based on computational chemistry.
The basic idea of virtual screening is: for a large number of compounds which structure is known, we use a computer to simulate its interaction with a given target.

Introduction Mixed ionic-electronic conductors based on oxygen-hyperstoichiometric La2NiO4+δ with the K2NiF4-type structure are of substantial interest for high-temperature electrochemical applications, including solid oxide fuel cell (SOFC) cathodes and dense ceramic membranes for oxygen separation and partial oxidation of light hydrocarbons [1-3].
This requires a deep experimental and theoretical study focused on the defect chemistry relationships in nikelatebased compounds.

Effect of Annealing on the Structure and Dielectric Properties
in PZT-PCoN Ceramics
N.
X-ray diffraction patterns revealed changes of crystalline structure after annealing, which could be correlated to the accompanied changes in dielectric properties.
In this study, we emphasized the effect of annealing on the crystal structure, and dielectric properties in PZT-PCoN ceramics.
This paper reports evolution of the perovskite phase, and crystal structure of the PZT-PCoN ceramics.
After annealing, a significant change in the crystal structure was observed, especially above an annealing temperature of 1,000 o C, where the crystal structure changes from pseudo-cubic to tetragonal and rhombohedral.

Abstract
Large part of life cycle cost of reinforced concrete structures, especially infrastructures, is
maintenance costs, where steel corrosion induced by chlorides is the major part [1, 2].
Concrete chemistry is different than that of the paste and common simulated pore solutions, or 2. the micro-structure of the concrete-steel interface is different [5, 6].
Thus, the micro-structure of concrete-steel interface may influence the levels at which concentration polarization occurs, thus affecting the chloride threshold and the localized corrosion development.
This result could be an indication for ITZ structure formation mechanism around vertical bars, which creates a microstructure that influences the fracture mechanism.
