Deflection of  base surface significantly reduced and the number of  roadway’s left side decreased 42 (0.1mm) after large-stone asphalt mixesl upper base has been constructed.
Chat3 tress of upper base's bottom surface () Chat4 tress of upper base's bottom surface () Table 3 stress analysis upper base's bottom surface Category σ1 σ2 σ3 cement stabilized macadam 0.81 0.35 -0.45 0.36 large grain size asphalt gravel 0.54 0.30 -0.14 0.34 Distance from the left side (mm) 875 875 875 875 The results show that when there are longitudinal cracks on cement stability lower subbase , tress of upper base's bottom surface σ1 is 0.81MPa(upper base is made by cement stabilized macadam).While upper base is made by large-stone asphalt mixes, it reduced 33%,to 0.54MPa. σ2 decreased more significantly, reduced 69%.Maximum shear stress is 0.36MPa when it made by cement stabilized macadam, yet it's 0.34MPa when made by large-stone asphalt mixes, the maximum shear stress decreased by 5%.

The surface of the samples with conglomerate coating are porous surfaces [10, 15] with grains size 0.1–0.25 μm Tribological tests were performed using CSM Instruments pin-on-disk type tribometer according to ASTM G99-05 [16] at an air temperature of 20.4°C and a humidity of 35 %.
During the study, an assessment was made of the coefficient of friction of a number of samples.

From the pictures, we can see that the grain shape of oxides looked like diamonds, and the oxide size at 800°C was smaller than that at 900°C.
Besides, internal oxidation in the interface of coating and substrate was observed at both 800 and 900°C, but the coating demonstrated better resistance to the oxidation at 800°C because the oxides on the coating surface were more compact at 800°C as well as the number of internal oxides was less than that at 900°C.

However, because the fine-grained sediments was easy to move in the naked tidal flat, the tidal creek had periodic north-south moving at the intertidal zone and the moving period was about 9 years.
Because a large number of sediment was supplied from the ancient Yellow River and the abandoned Yellow River Delta, the coastline of the study area moved seawards about 70km from 1128 to 2012.

Histogram equalization is for nonlinear tensile, redistribution image pixel values, the number of pixel gray level range about the same.
If the image has a horizontal grain, the COR in the horizontal direction matrix of COR value will be greater than the rest of the matrix.

The DMW is damaged on the boundary of the diffusion layer, wherein the base matrix has lower chromium content and undesirable carbides on grain boundary are examined. 5) The degradation process of DMW damage is repeated due to cyclic startup of Units. 6) Operation condition, mainly temperature, leads to the formation of secondary carbides due to diffusion process because the first deposit is not stabilized steel.
