The Table 1 does not list average complete rate of maintenance material with equipment of single vehicle(X17)and reliability of 1,000 km(X5),because maintenance material with equipment (including record and so on) as file of equipment, which has always been highly valued by maintenance management and technology staff, and has been fully equipped.
According to the above analysis, reliability of 1,000 km, MTBF, failure rates, failure repair hours, maintenance costs per 100 km, complete rate of maintenance material with equipment in the original parameter system are eliminated.

The duct system includes an acoustic source and two ducts connected outside, which are all made of PMMA material.
The material and structure can be replaced at ends of the circular pipe to change the acoustic impedance of ends.
The diaphragm vibrating speed is measured through PMMA material using a laser vibration meter of Polytec OFV-5000.

Abstract
Among all biomass resources the work concentrates on one of the most important fuel source - dendromass.
Fossil fuels replaced the wood used for energy purposes, athough wood is the longest used renewable raw material.
Materials and Methods Plants use carbon dioxide contained in the atmosphere which is converted into hydrocarbons using photosynthesis.

The definition of a comprehensive decision function Totally represents the comprehensive factors of the merger process in Eq. (1).The comprehensive effect of Total function value depends on factors such as the layer thickness [9], forming time, extrusion speed and filling velocity and their interaction, the opening and closing delay, the amount of compensation, nozzle temperature and forming chamber temperature, material shrinkage.
But the material shrinkage can be identified in the molding material is determined, although the molding time on the precision influence but when molding structure is determined, the complexity of each area and shape also determined, so the Total of these two factors on the impact of the same value of each loop.

Construction projects’ features of being enormous in size, lengthy in time, material-intensive, consumptive in the using of equipment, fixed in products, mobile in construction process, and vulnerable to natural and social environmental influences bring about uncertain and unavoidable risks for the contractors[1].
