As a remedy, reinforcement consists of combination certain materials with some desired properties with soil lacking those properties [2].
In addition, PP fibers are used to reduce the shrinkage properties and to overcome chemical and biological degradation[27, 28].
The physical properties of the soil are shown in Table1.

From Table 1, the mechanical properties of semi-crystalline PLA are attractive, especially Young modulus, as PLA is favored for short-term packaging.
The plasticizer also purposely used in the mechanical and thermal properties enhancement.
Commonly, the amount of plasticizers that range from 10 to 20% is required to provide both a substantial reduction of Tg of the PLA matrix, and adequate mechanical properties.
The temperature, molecular weight, and shear rate are the factors in determining rheological properties.

The course of the energy accumulation is affected by multiple factors such as temperature
and the load program [9,10].
The strain energy is also affected by temperature.
Based on the analysis of the developed graphs, it can be concluded that the change of cyclic properties of cast steel depends to a small extent on the sequence of the load program stages.
The energy changes confirm earlier observations indicating that plastic strain energy DWpl is the parameter of the hysteresis loop that is least sensitive to changes of cyclic properties.

Energy efficient building in the United Kingdom in the technical measures three main areas: 1) use of structural measures to raise the walls, roof and windows of the thermal insulation properties; 2) the use of solar energy; 3) improving the heating system.
Community planning, the district's location, residential building orientation, spacing, height, body type, and district road network structure, greening the environment will affect the district's sunshine, ventilation and climate environment and thus affect the energy consumption of residential buildings.
Community greening and water can effectively reduce the temperature, humidity, wind wind, improving the ventilation quality, thus inhibiting production of heat island effect and improve the structure of residential buildings outside the maintenance of thermal properties.
The sun through the windows of the incident to the indoor heat whose value is the size of the addition to the orientation of windows, size, location and other factors, the availability of shade facilities and there is a great relationship.
Stairwells should use a good thermal insulation property of windows and doors, the open-closed stairwells instead.

In mechanical loading of solid bodies, the impact of the surface properties on formation and spreading of surface cracks is obvious, mainly as regards cyclic loading.
Therefore, it is important to pay attention to knowledge of surface properties and their improvement.
Cold plastic deformation is the easiest way to change the mechanical properties of the materials.
Cold plastic deformation is the easiest way to change the mechanical properties of materials.
However, we must also take into account metallurgical and physical impacts, as well as material properties.

The friction and wear mechanism of diesel engine was studied and the wear factors of diesel engine friction and wear was analyzed.
During diesel engine running-in stage, friction and wear of friction pair affected by lubrication and temperature.
So the main factors of friction pair wear is force, structure parameters and mechanical precision.
Ferrographic analysis pays an important role in tribology system wear process and analysis to study the mechanical parts, the wear failure type and wear mechanism.
The wear rate is small, stable during diesel engine early running-in stage wear increase, and little change in middle of running-in wear stage; In later period, with the extension of time, the friction pair surface fatigue damage accumulation, wear increase for material properties.Wear particle evolution images of diesel engine during running-in stage is shown in Fig. 4.

The temperature will result in the variation of gear thermal deformation[5-7], the existence of the thermal deformation causes the gear tooth error. it makes tooth thickness increase and cause the gear tooth profile, affecting the gear transmission error. thermal deformation of different locations are different and it impacts on the transmission smooth of gear.
The calculation of gear thermal deformation need to consider three factors.
Second, thermal expansion properties of structural materials.
Gear geometrical parameters and material properties such as table 1 and table 2 show.
