When such pipelines transport crude oil or other viscous materials during the cold weather, they must be heated to reduce the oil viscosity and transport resistance to improve efficiency.
Rigid polyurethane foam is a novel and effective heat insulation material.
GRA program provides a practical method for analysis of the impact factors of materials in electrical heat tracing, and it can be further developed by C# language to avoid complex mathematical operations, so it not only saves the manpower and material resources but also becomes convenient to users.

After computation, an optimized shape and material distribution for the structure was shown.
Topology Optimization is a mathematical technique that produces an optimized shape and material distribution for a structure within a given package space.  
By discretizing the domain into a finite element mesh, material properties for each element can be calculated.  
An optimized shape and material distribution for the hood structure appeared, and a pattern of shape variable-based reinforcements within design region was generated.

The construction effect of passive protection system The analysis of expressway slope flexible protection method and other protection methods in comparison The traditional protection engineering uses rigid materials which are composed of cement, stone, concrete and so on for the main building materials.
In the broken slope surface, when a large number of lose materials, pumice stones and high water sensitivity rocks appear, the adhesive strength of the protection structure and slope surface is difficult to guarantee.
The mechanical equipment and materials of passive protection required are more than other methods of solid.
The mechanical equipment and materials of passive protection required are more than other methods.
