A new approach of cascade utilization of the chemical energy of fuel

The indirect release of chemical energy of fuel is investigated, and a new mechanism is proposed to identify the cascade utilization of chemical energy of fuel more clearly. Based on the concept of energy level, the internal phenomenon of the indirect chemical energy release is disclosed, and the equations of energy level describing the utilization of chemical energy and thermal energy during the indirect chemical energy release process are obtained. From theoretical analysis, we find that the superiority of the indirect chemical energy release of fuel comes from the cascade utilization of the fuel's chemical energy. Moreover, the cascade utilization of chemical energy is verified by the investigation of CRGT (chemically recuperated gas turbine). As a result, the thermal exergy obtained from the chemical energy release of fuel increases by 2%?3%. The results obtained here may help a deeper understanding of indirect chemical energy release of fuel and provide a theoretical basis for the synthesis of innovative energy systems.     

Existence of Young measure solutions of a class of singular diffusion equations

The first initial-boundary value problem of a class of singular diffusion equations with the flux sublinear growth and the potential without convexity is investigated. Such equations may be strongly degenerate, singular and forward-backward. Inspired by the idea in a recent work of Demoulini, we first discuss the regular case by introducing the Young measure solutions and prove the existence of such solutions. Consequently, we approximate the extreme case by the method of regularization. By means of some uniform estimates and some techniques, the existence of Young measure solutions with bounded variation is established.     

Effect of concentration of wool keratin on the rebuilding of disulfur bond

We demonstrate the effect of concentration of extracted keratin on the rebuilding of disulfur bond during dialysis against deionized water: cross-linked networks can be formed in the aggregate when the concentration is high, whereas at low concentration, intramolecular disulfur bond is preferred. This preliminary study illustrates, for the first time, the potential of controlling the cross-linking between keratin chains by facile means without addition of other chemicals, which is helpful to construct the biomacromolecular self-assemblies.

Modeling Experiment of Break of Debris-Flow Dam

Glaciers are extensively developed in the southwest of Tibet and the moraines are widely distributed with large depth. Large-scale debris flows are often reported which blocked rivers and formed dams. In this paper, seven large debris flows in four valleys are discussed, among which five dams developed. 13 sets of experiments have been conducted in laboratory to simulate the formation and failure of the dam. Finally, a model of dam failure is proposed and a formula is established to calculate the flood discharge： Q=kbnnk/TB^-/LG^0.1,where bk is the outlet width of the dam at the original water level, hk the erosive depth, T the time from overflow to final state of failure, the average width of lake; L the length of the lake, and G the total potential energy of the water in the lake.     

The orientational preferences of backbones of proteins

The orientation between the backbone residues of proteins is defined based on the local configurations and the corresponding preferences are analyzed by statistics.It is found that all the residue pairs have some specific preferences of orientations.The statistical analysis is mainly concen-trated in the orientational distributions for two kinds of groupings of residues based on the hydrophobicity and secondary structural features.The statistics for such two types of groupings shows different orienta-tional preferences.It is found that for the former grouping the orientational preference is rather weak, while for the later a kind of strong orientational pref-erences.This suggests that the formation of local structures and of secondary structures are highly related to the orientational preferences.

Kinetic Parameters of Thermal Degradation of Polymers

The derivative expressions between activation energy(E) and the temperature at the maximum mass lossrate(T_(max)) and between activation energy (E) andexponent (N) were deduced in the light of Arrheniustheory. It was found that the increase of activationenergy results in the decrease of exponent and the     

Variations of optic properties of water under action of static magnetic field

Effects of static magnetic field on optic properties of water are investigated by infrared spectroscopy, ultraviolet spectroscopy and X-ray diffraction, respectively. The ultraviolet spectroscopy experiments show the changes of properties of water under action of static magnetic field, in the region of 191 to 400 nm. The infrared experiment shows that the water exposed in a magnetic field had saturation and memory effects. The magnetized effects increased with increasing exposed time, but were weakened with increasing of time when the magnetic field was removed. In the X-ray experiment, the strength of diffraction increased also, after the water was exposed in magnetic field. Meanwhile, the shift of peak and increase of strength of X-ray diffraction of magnetized water added with nanoFe3O4 occurred as compared with that of pure water added with nano Fe3O4. This result suggests that the magnetized wa- ter has certain magnetism. Finally, these phenomena are simply explained by the molecular structure of water and the theory of magnetization of water.

Summarizing the Methods of Determination of Rational Completion Status of Cable-Stayed Bridges

Cable-stayed bridge is a high-order hyperstatic structure. The size of cable force affects the stress of the structure greatly. The key problem to detemine the rational completion status of cable-stayed bridges is how to control cable force on completion status. Surrounding this problem, domestic and foreign experts and scholars have done a lot of favorable work and obtained much achievement. On the basis of comprehensive reading domestic and foreign relative documentation, the author of this article classifies rationally the current researching achievement, comments and compares advantages and disadvantages of each method and lists two synthetic methods＇ detail steps and puts forward the researching emphasis of the field will deflect to synthesis several methods to determine the rational completion status of cable-stayed bridges     

Dirichlet Form of Product of Variational Fractais

Much effort has gone into constructing Dirichlet forms to define Laplacians on self-similar sets.However, the results have only been successful on p. c.f. (post critical finite) fractals. We prove the existence of a Dirichlet form on a class of non- p. c.f. sets that are the product of variational fractals.
