： As the temperature decreases, the units damage energy of asphalt mixture can have a corresponding reduction, For example AC-16 admixture asphalt mixture, when the temperature dropped to -100C, the damage energy of the mixture reduced to 0.013239kj/m3, when the temperature dropped to -20 0C, the damage energy of the mixture reduced to 0.011419kj/m3.It sescrips that as the temperature decreases, ability to resist deformation of asphalt mixture becomes weakened, deformation from viscous excessive to almost perfectly elastic.

Two semiconductor LDs with wavelength 640 nm and 750 nm were used to identify the IS data for different sub-cells, All the IS data were analyzed by the Z-view software. with frequency range from 0.1Hz to 1 MHz.
Result and discussion The Z″–Z′plots of sample measured in dark and under LED illumination are shown in figure 2, For the data from 640 nm LD illumination, the obtained R and C of the three sub-cells could be compared one-to-one with those measured in dark, according to the constancy of capacitances (changed weakly by illumination). and Ct were identified.
For the 750 nm illumination, the reduction of was much more remarkable.

The EMF of reactions in inert anode In order to meet the environmental protection and the cost reduction, the research on inert anode[4,5] should be one of the directions in electrolysis.
According to the thermodynamic data, and of Eq. 6- Eq. 9 could be computed.

In many cases this is not sufficient for settlement reduction, especially if there is a risk of high cyclic/dynamic loading.
Filling the end of settlement cloud Observation data accumulation finally arrive at settlement observation changes with time graphics, see Figure 6.
Figure 6.The settlements in the DK369+520 with days 5 Conclusion Based on the measured data and the simulation results obtained the following conclusion: (1) In the cross section of embankment, the settlement rate reduce, the late settlement is basically stabilized.
(4)Through comparing the data of two aspects, we think that this model can better reflect the soft soil subgrade settlement process.

Data of suspended sediment concentrations (SSC), currents and water levels at observation stations were used to study the suspended sediment transport by the method of mechanism decomposition.
Delta was discarded due to the reduction in the supply of sediment.
Initiated for the purpose of harbor extension, as well as the increased use of coastal and near shore sites for industry and leisure activities, this paper aims to the studies of the suspended sediment transport using field observation data.
The current velocity data were measured using SLC9-2 direct-reading current meter at six layers: the surface layer, 0.2 of the water depth, 0.4 of the water depth, 0.6 of the water depth, 0.8 of the water depth and the bottom layer.
Detailed examination of the current data and SSC, it is found that tidal pumping transport is related to the tidal asymmetry and suspended sediment vertical concentration gradient.

Based on the acoustic emission data recorded using the acoustic-emission software and hardware complex during the experiments, a method for estimating the accumulated damage using various techniques for analyzing acoustic emission parameters was tested.
Data on the distribution of the probability density of the maximum amplitudes and the median frequencies of the AE signals recorded at each step of the test are shown in Fig. 5 and Fig. 6 respectively.
To determine the stages of accumulation of damage in the PCM, data on the peak distributions at each step of the test were used (Fig. 7).
Fig. 7 Distributions of the probability densities of the AE signals amplitudes (squares) and the median frequencies (rounds) registered for the fiberglass flap Steps 2-nd through 4-th are accompanied by a decreasing of amplitude values, which characterizes the reduction in the scale of damage.
