In recent decades, due to the progress in modern science and technology, especially the appearance of new progress and the associated instruments of gas geochemistry and isotope geochemistry, it has promoted the inorganic gas hypothesis to develop to the modern inorganic gas hypothesis science-based.

Material parameters can be seen in table 1; the model’s mesh generation and the cloud chart of vertical displacement are shown in Fig.1 and 2.
(4) Response analysis of fatigue breakdown of pavement materials In the later period of the bituminous pavement, the structural layer’s anti-bending capacity is reflected by the allowable tensile stress [3,4].
Thereinto: (1) In the formula: ——allowable tensile stress of materials of the pavement structure layer, MPa ——splitting strength of materials of the structural layer, MPa; ——structural coefficient of tensile strength As for asphalt concrete pavement (2) As for inorganic binder stabilized base (3) In the formula: ——highway classification coefficient, that of expressway and first-class highway is 1.0, that of second-class highway is 1.1; ——grading coefficient of bituminous mixture, that of fine and medium-grain bituminous concrete is 1.0, that of coarse-grain is 1.1; ——accumulative equivalent axles of a lane in the design life.
It is calculated that the additional stress of the basement layer of the bituminous pavement is greater than the allowable tensile stress 0.22MPa and the pavement is damaged by fatigue cracking when the ratio of alter gradient of differential settlement in the later period exceeds 0.25%, which can be the control standard for differential settlement with regard to fatigue attenuation of bituminous pavement materials. 2.2 Control standard and classification of differential settlement (1) Control index of differential settlement In the paper, the control target of differential settlement is confirmed in overall consideration of tensile strength and fatigue properties of the pavement material.

Among all the solder material, the tin-lead alloy solder is used most widely and its consumption in China is beyond ten thousand tons.
For example, IBM, AT&T, Bell, Motorola and Sandia national laboratory put a strength into the research of this kind of important Metallic Functional Materials, NCMS united eight companies which value 10 million dollars such as GM-Delco Electronics and Ford Motor Company cost 4 years to research dozens of substitution for Sn-Pb soldering filler metal, among those substitutions, Sn-3.8Bi, Sn-3.5Ag-4.8Bi and Sn-3.5Ag were considered as the most promising material used in microelectronics surface assembly.
The result shows that soldering filler metal can achieve good property under rapid solidification, for example, ultra refined of grain can make material gain high strength and toughness.

Parameters.
The loss of this material severely affects the metals industry.
The arc heats both the start material and the electrode tip; eventually both of them melt down.
In this way materials loss due to shrinkage is compensated by the molten metal and shrinkage cavity gets chance to come up.
