The calculations showed that, if the self-gravitation of the radiated particle is taken into account, the radiation spectrum deviates from exact black body spectrum and the rate of tunneling equals precisely the exponent of the difference of the black hole entropies before and after emission. The conclusion supports the viewpoint of information conservation.展开更多

Hence, the corrected Klein-Gordon equation will be more precise on the expression of the tunneling behavior. Then, the corrected Hawking temperature of the Gibbons-Maeda-Dilaton black hole is obtained near the horizon by quantum gravity. Analyzing the results carefully, it is obvious for us that the tunneling result is not only related to the mass of black hole, but also related to the mass and energy of outgoing fermions. Finally, we also infer that the tunneling radiation would be stopped at some particular temperature.展开更多

The original staff and workers as well as equipment and machinery have merged into various independent professional companies. The features in quality management for the Maeda are as follows: following unremitting efforts and education, all the employees have the quality consciousness; the professional company has more advantages in quality control of construction; mechanization and automation can reduce maximally the artificial factors affecting quality; more attention are paid on the introduction of the new technologies and new work processes in order to improve the construction quality; and each specialty has a set of work process very easy of operation, to ensure the quality.展开更多
