040 Review Resource Tax

Resource tax, which has over twenty years history in China, now face its another reformation. Last year, resource tax is less than 1% of China＇s 11 trillion revenue. But resource tax has important meaning： saving resource, protecting environment and zoology. However, the fact is we have less and less resource and worse and worse environment. Of course, resource tax has not been finished. Three years ago, resource tax, which had been keeping silence for over 16 years, started at Xin Jiang province with oil and gas as a break.

Adjusting the balance of radial bogie changed from existing C0 -C0 locomotive bogie
ZHENG Ze-ye, HUANG Zhi-hui, HONG Ming-hu （Traction Power State Key Laboratory, Southwest Jiaotong University, Chengdu 610031, China）
Abstract： Because the value of wheel＇s longitudi- nal orientation rigidity is very high when the CO - CO lo- comotive runs on curves, the wear between flange and rail side and the lateral force between wheel and rail will in- crease, the adhesive performance of locomotive would be influenced. Changing oxisting bogie into radial one can solve these problems. But the other problems,

CONTENTS

Abstract： The combined heat exchange model of the molten salt and heat storage concrete is established. Using numerical simulation meth- od and Fluent software, the influence of the thermal conductivity of the concrete, fluid pipe geometry, thermal fluid inlet temperature and inlet velocity and other factors on the thermal storage law and its character- istics of the thermal storage unit is analysised. The conclusion of nu- merical computation is given as follows：when the thermal conductivity of the concrete is
