As can be seen that rh is three times proportional to temperature, its value varies dramatically during heat conduction,  is a material coefficient,  is a constant relative to material and radiation.
(e) Under current structure, to lessen heat deformation failure, materials with higher strength, reasonable bending load, lubricants with low viscosity and good heat conduction property were suggested.

Practice has proved that the methodology of constitutive model determination for metal cutting deformation, proposed in the present study, has advantages when compared with using one method alone, and is more suitable to establish flow data for the various materials in the metal cutting process.
Thus, it is more suitable to establish flow data for the various materials in the metal cutting process.

As a series of excellent performance, the C/C composites as seal materials in aero-engine shaft have been paid much attention[5].
The contrast finger seal made of a metal material to optimize uses cobalt-based alloy GH605 as finger’s material.
The rotor’s material is 40CrNiMoA; the black plate’s material is 1Cr13.

In reference [10], a multi-purpose vibration friction testing machine was invented to study the friction and wear behaviors of the material with or without vibration, it also studied the effect on the wear characters of nonmetal materials or friction materials under vibration.
The test studied the relationship between the nature of the soil, vibration frequency, amplitude, acceleration and the degree of material compaction by measuring the physical quantity such as acceleration, pressure and density of materials.

The usage of lightweight materials in construction has become increasingly popular due to huge available of such materials either artificially made or from industrial and organic waste.
Among the lightweight materials that have been used as materials in construction are extruded polystyrene, foamed concrete, lightweight aggregate, plastic bottle, aluminium, and even products from plantation such as peanut shells and rice husk.
Studies have proven that certain materials mentioned above are viable to be used as building materials.
The proportion for the materials used to cast the concrete beam is presented in Table I.
The proportion of these materials were measured by weight.
