Since the electrical resistance of the most materials depends significantly on the temperature, the resistance of the material is measured to determine the temperature.
The final step is the complete removal of the monocrystal silicon in membrane area to reduce the "parasitic" effect of the substrate and to remove the mechanical stresses conditioned by differences in the temperature of various materials’ films formations.

As a matter of fact, it also has many harmful characters as fuel oil based on many studies on different pyrolysis materials, including unpleasant odor, high water content, complex constituents and chemical instability, and so on.
Materials and methods Characters of sewage sludge The non-digested sludge after mechanical dewatering was collected at a wastewater treatment plant in Tangshan, Hebei Province, China.
The organic composition of pyrolysis oil can not be obtained with GC-MS for a mount of solid particles and other materials harmful to GC column.

Simulated annealing Simulated annealing is a neighborhood based optimization method inspired from technique used to have states of low energy of material.
The energy of a material can be viewed as a cost function of the optimization problem.
The different states of this material can be considered as solutions of the cost function.

Numerical Simulation for the Damping Effect of Empty Holes on Blasting Vibration BIAN Kaifang1, a, LI Haibo1,b and LIU Yaqun1,c 1 Institute of Rock and Soil Mechanics, The Chinese Academy of Sciences, Wuhan China ajunlintianxiabian@163.com, bhbli@whrsm.ac.cn, cyqliu@whrsm.ac.cn Keywords: Empty holes; Damping effect; Blasting vibration; Influencing factors Abstract.The two-dimensional discrete element program (UDEC) is applied to simulate the dampi- ng effect of empty holes on blasting vibration.
Physico-mechanical parameters of rock material are shown in table 1.

Furthermore, the damping empty holes can be filled with vibration-absorptive material to have better damping effect in practical engineering.

Judging Criterion for Ergonomic Factors The ergonomics, a science based on the psychology, physiology, anatomy and anthropometry, covers the research on how to make the design of man-machine-environment system fit the physical, physiological and psychological characteristics to achieve the optimal matching of man, machine and environment and allow people under different conditions to work and live effectively, safely, healthily and comfortably [7].
In the field of automobile recall, the automobile products defects mainly fall into three categories: design defect, which means the potential defect existing in the use of products due to insufficient consideration at the initial design phase because of technical limitation and improper material selection, etc.; manufacture defect, existing in a batch of products and caused by the deviation, error or negligence in certain procedure or link during the processing, manufacturing and assembling of products; identification defect, also called the indicative defect, meaning the informative defect of products due to failing to provide complete operation instructions or warning instructions that satisfy the safe use requirements [8].
Discussion The analysis on the ergonomic defects in the automobile recall cases in China in 2012 shows that, the ergonomic defects generate because the ergonomic factors are not being taken into account in the design on the one hand, and the material and model are not properly selected on the other hand.
For this reason, it is suggested that the automobile enterprises incorporate the ergonomic parameters into design and strengthen the study on material and model selection in manufacture.

When the uneven stress and material defects of the shaft are superposed, that is the main affecting factor of spindle bending.
At the same time, we know that the maximum stress of the wheel hub does not exceed the yield limit of material and the impeller is still within the scope of elastic deformation after completing interference fit.
The maximum stress of the concentration region does not exceed the yield limit of material.
