The reconstruction results are based on decomposition of Novikov＇s inversion operator into three parts bounded in the L2 sense. The first part involves the measured partial data; the second part is a skew-symmetric operator; the third part is a symmetric and compact contribution. It is showed firstly that the operators involved belong to L（L^2（B）. Furthermore numerical simulations are conducted to demonstrate the effectiveness of the developed method.展开更多

The survey covered 23 cities whose annual radon concentrations range from {14.9} to {246.4} Bq·m{-3} with an overall arithmetic mean value of {106.7} Bq·m{-3}. The average annual effective dose received by people working in these underground working places was {1.6} mSv, hence the lifetime fatality risk was {1.2}×10{-4}. Fujian Province had the highest radon level during the survey. It is better to reduce the radon concentration heavily in summer because of higher radon concentration than in winter.展开更多

It tells the story of Dr. Rappaccini, with drive of morbid scientific zeal, raises his daughter as the bodily poison. The paper is intended to explore how Hawthorne delivers his black vision on human nature in light of the structuralism.展开更多
