Thus reduction of number of sensors reduces probability of early detection of defect of lining.
It occurs at the expense of formation of blind zones (laying sites for which creation of model of a crazing is impossible because of a lack of initial data for modeling).
For reduction of influence of an measurements error it is necessary to increase distance between thermocouples of one sensors group.
It allows increase accuracy of calculations: for reduction of influence of an error of thermocouples measurement it is necessary to increase a measured difference of temperatures.

Then using the sample data of some feature points on the mining sequence, it has revealed the temporal effect characteristics on soil physical and chemical properties and ecological environment caused by coal mining subsidence, and further put forward some countermeasures for control and remediation.
Soil bulk density went through a process of gradual recovery after the first reduction in the uniform subsidence region, the changes of the disturbance degree of coal mining is the main reason.
The damage characteristics of soil moisture content also exist obvious partitioning feature, soil moisture content basically recover to pre-mining state due to the closure of dynamic ground fissures and the stable subsidence of the goaf after a rainy season and ice period, which shows certain “self-healing” capabilities next spring in the uniform subsidence region(USR), soil moisture content is always in low in the differential subsidence region(DSR), ground fissures become a major factor which leads to the reduction of soil moisture content in the coal mining subsidence area.
The reason may be as follows: soil erosion affects the decomposition, leaching and deposition of organic matter and minerals, the changes of microbes living environment has led to reduction of humus and this process has certain continuity, the length of effects on soil chemical properties made by mining is relatively large, which needs to be supplemented by artificial restoration, such as the restoration of ground fissures to block the drain channel and so on.

As can be seen from Figs. 2 and 3, replacing the river sand with RPB resulted in significant reduction in the mechanical properties of the geopolymer concrete.
The low elasticity modulus of the crumbed rubber caused the strength reduction in geopolymer.
The strength reduction with increased RPB content could also be explained in a similar fashion.

By changing the loading angle, α, from 0° to 90°, mode-I, mode-II and all mixed-mode data were created.
With Arcan specimen, by changing the loading angle from 0° to 90°, mode-I, mode-II, and all mixed-mode loading data were obtained (Fig.2).
Increase of loading angle from 0 to 90° leads to a vast reduction of strain energy and this causes a great increase of fracture resistance of structure.
By changing the loading angle, α, from 0° to 90°, mode-I, mode-II and all mixed-mode data were created.

Hall-Petch relations do not fit to the experimental data This can be ascribed to the texture effect.
Especially, due to its high specific strength, magnesium based alloys offer a highly potential in weight reduction of automobile resulting in less emission and more efficiency.
However, the data obtained in the present study do not fit to Hall-Petch relationship as shown in Fig. 5.
Hall-Petch relations do not fit to the experimental data obtained in the present study.

Impact factors Abstract: Rutting is one of the most hazardous damage form of asphalt pavement.But,owing to itself inherent in the viscoelastic characteristics of asphalt mixture,the diversity of factors influencing the high temperature of asphalt pavement anti-rutting performance and the complexity of rut formation,this three reasons make ruts become a worldwide problem.Starting from the mixture.This article analyzed the influence factors of the rutting resistance of asphalt mixture at high temperature.For asphalt mixture, through the experimental data, the research status at home and abroad, from the type of asphalt, asphalt content, grading of aggregates and air voids four aspects analysis and study the influence factors of the stability of asphalt mixture at high temperature.

Nanoparticles will inevitably enter water environment, while there is little data on aquatic plants which play an important role in aquatic ecosystems.
In contrast, significantly reduction while exposed above 150 µg/L in dry weight was observed.
