Application of antomatic image-seperated technique in high slope heavy load railway section;

Dynamics analysis on heavy loaded soft startup system based on differential planet gear train;

On the design method of heavy load asphalt pavement;

The necessity to mount the empty/load brake equipment on heavy haul freight cars due to change of the gross-to-tare ratio in order to reduce empty-car brake cylinder pressures is analyzed.

The technical development railway freight transport equipment in our country is expounded from the aspects of quickness, heavy haul and specialization.

In the algorithm suitable for dealing with the VHLD grammar conflicts, various kinds of overloading and elabrations for the static level are put forward.

Practical semantics are assigned to OSCARⅡ in the fields of class definition, encapsulation, inheritance, overload, etc.

In the paper the author discusses the properties,events and functions of Mdiclient object and Menucascade object,and makes a detailed analysis of their function overload and event message queues.

The serious overloading of vehicles and the shortcomings of highway surface designs have left many highways in early fatigue cracks and tracks.

Three kinds of overloading pheomena in Ada langunge are listed,and a binary tree structure for expression allocation is built at first.

Function overloading permits one function-name to define multiple functions.

Research on the Design Parameter of Heavy-haul Line;

By putting 10000-ton heavy-haul trains into operation,increasing effective len.

The paper points out that a thorough study for vertical dynamics of long empty tank trains should be carried out so as to keep up with the development of heavy-haul transporation.
