The data shows that: ① The scale of rural sewage treatment facilities is generally small.
In addition, the data in table 1 shows that: ① In rural, collection and pick-up were the main way for garbage disposal and had low efficiency.
In 2011, 74 demonstration projects on rural continuous environmental governance were implemented, a small part of rural brought sewage and garbage disposal into force simultaneously; in Guangxi, only 19 sets of household garbage collection treatment systems were completed including 4 waste transfer stations, 5 garbage carrying vehicles and 41 arm type rubbish transport vehicles; meanwhile the urban and rural garbage integration treatment mode — “household classification - village collection - township transfer - county treatment” is only carried out in the regions of nearby towns and convenient transportation; the mode of “household classification - village collection” was formed basically in most rural, but garbage had no effective disposal; destructors were purchased in some scattered and bad transportation rural, the mode of classification in source and reduction in situ was carried out in these rural, this simple burning with no smoke prevention would bring secondary pollution to the

Although the completion methods which open degree are not perfect of conventional vertical wells inhibited or slowed down the bottom water coning partially, because of the reduction of the contact area of wellbore and reservoir, which also reduce the production capacity of well at the same time and the critical production is often low.

The minimum temperature of the test is -50°C.The loading process and data acquisition are controlled by PC automatically.
Conclusion According to the research results and the experimental data, a description of frozen soils can be obtained.
With the reduction of temperature, the decrease of ice strength compared with the increase of soil strength due to bonding effect, the ratio reduces.

Such approach has two positive effects: i) reduction of the graphite die wear and ii) controlled preparation of layered materials.
Obtained results were compared to data from work Savio et al. [12] where alumina and zirconia-toughened alumina (ZTA) ceramics at lower thickness were investigated.
Normalized data from the mentioned paper supplemented by current results clearly show linear dependence of DOP on thickness of alumina ceramics.

The measurement of the order parameter was conducted with deuterium Nuclear Magnetic Resonance (NMR) spectroscopy using an ECA-400 JEOL NMR Spectrometer with ALICE software for data acquisition and spectral processing.
This point is further supported by the data shown in Figure 3, which relates the temperature dependence of the quadrapolar splittings for the deuterium NMR spectra of the pure 5CB-d2 and that of the 5CB-d2 embedded in PVA.
As the temperature is increased, the quadrapolar splittings are reduced, in keeping with the reduction of the orientational order, only to a difference of about 10% at 320C.

At the same time, according to the data of the Ministry of Culture of the Russian Federation, 420 cultural heritage sites are located in Orenburg, of which 17 are of federal importance, half are of regional importance and the second half requires a state historical and cultural examination to determine the historical and cultural significance.
To achieve these goals, the following tasks were set: collection, analysis and sistematization of information on the development of the city (historical, archival, project materials, demographic, sociological data on economic development) and conducting a retrospective analysis of the historical development of Orenburg.
This decision can be related to two reasons - economic (lack of funding) and strategic (reduction of attacks by foreigners).
