The rail is a potential or real rule and criterion through which the society functioning can be maintenanced and one can be acquiesced,accepted and admissed by the groups of society.

The Article aims at providing resolution for crack which is caused by carbon compound segregation,grain-size overlevel and high temperature of quenching through analyzing the crack of CrWMn guide-way plate and inspecting carbon compound state,grain-size after forging,and martensite.

Research on dynamic characteristics of slab track-roadbed systems with soft rock as embankment filling under high speed moving load;

Analysis method of dynamic responses on slab track;

Structure parameter influence of slab track for high speed railway on wheel-rail noise;

To analyze the stresses in slab track structures on soil subgrades,a finite element model was derived.

The paper devotes to discuss the behavior of the temperature loading on the slab track.

Up to now,there is no ballastless track in such cold area at home and abroad,so it is necessary to do the experimental research on the manufacture of CRTS I ballastless slab of passenger dedicated line in cold area to make the durability and frost resistance of the slab meeting the requirement of cold weather and to form the manufacturing technique.
