The current method for testing the quality of the compaction of the roadbed can be divided into three categories: the Filling water (sand) method, the Wave method and the Static penetration method.
Filling water (sand) method[1] they had to be the test pit excavation, low efficiency, unable to meet the rapid mechanization of construction of the embankment construction.
The transport unit is a truck through professional transformation function is to ensure that the motion detection, as well as truck weight to act as the reaction of the reaction; mechanical unit consists of the reaction frame, activities manipulator, positioning frame, burrows and controller constitute the main function is the acquisition positioning, automatic hole automatically remove the punch, and automatically insert the detector automatically backfill detection hole; hydraulic unit for the holes and static sounding to power; acquisition unit consists of several groups were "*"-shaped arrangement of static cone probe and the fixed support frame and the hydraulic drive unit composition, role is the maximum pressure data collected at different depths of Cone probe equidistant squeeze; data acquisition storage processing unit by the data logger and a computer composition.

Coal seam cavity technology.The professional cavity bit of CBM produced by the institute of exploration techniques of the Ministry of Land and Exploration is adopted.
The drilling is in under-balance situation, which will be useful to prevent water blocking damage brought by high differential pressure fluid.
As a result, many problems in Binchang mining area, such as water-shortage in construction, collapsing and breaking of coal-bearing strata, and mud loss in fritted rocks section, can be solved.

The U.S. definition of energy-saving and environmental protection industry between OEDC environmental protection industry and environmental protection industry, they divided it into three categories: energy -saving and environmental protection services, environmental protection equipment, and environmental resources.[2]This paper focuses on energy-saving and environmental protection equipment, which mainly includes: oil-water treatment equipment, instruments and information systems, air pollution control equipment, waste management equipment, cleaner production and pollution prevention technologies and equipment.
For an industrial enterprise, the establishment and implementation of product image is a gradual process, whether start from the business inside, or in collaboration with a professional design company, the first selection of a suitable product design is the safest and effective way to ensure the accuracy and adaptability of the latter system.[6]The selection should satisfy a number of conditions: the product is typical, to reflect the typical characteristics ; easy to grasp the characteristics and features; mass production and smaller craft restrictions;structural engineers and industrial designers should participate the selection of product meanwhile.

Tourmaline is endowed with spontaneous polarization which enables it to generate an electric field on the surface, which facilitate the photoelectrocatalytic effect of sub-micro/nano-grade ZnO and may be helpful to improve ZnO's electromagnetic properties according to the built-in field theory[4] because of the two reasons below:
(1)Tourmaline facilitates the capture of holes
Tourmaline's surface electric field may drive water molecules to be ionized, which results in reduced water molecule groups, enriches the concentration of OH-, facilitate capturing holes and reduces hole's constraint on electrons on the surface, thus enhances its conductivity.

.<0}According to the result of this research, the improved continuous type mixer has performed very well in several aspects including flowability improvement, water reduction, the increase of maximum application thickness, compressive and bending strengths, and the decrease of rebound loss.
Because repair work is becoming difficult due to negative construction environments, including the large scale of construction projects such as new buildings, increased labor costs, and lack of professional technicians, mechanized construction has become a required alternative for repair work.
The improvements included extending the mixing sections to realize transportation distances of up to 80 m, increasing the discharge rate up to 40–90 L/min by mixing water and powder simultaneously through high-speed spinning over a short distance, and installing an additional mixing blade to the horizontal wing section of existing fan-type mixers to mix materials sufficiently.

Former world rowing champion, Norway's Einar Resmussen holds the potential to stimulate the development of new principles of water leaves rowing.
Although this is not yet in commercial use rowing on, but carried out in an international rowing regatta person meeting (held in Germany, Duisburg) with the "principle of water leaves the ship," the prototype demonstration before, the results show that it is suitable for the ship's first Flyak a pattern.
Currently, more than 90% of the world's professional hockey game, mostly using composite hockey stick.

Abstract.
Moreover, they often blindly raise the floor and the road so that internal and old houses of the village can not drain rainwater and sewage (more village have no underground drainage facilities, so the water of rain and snow is natural discharge by surface), and residential environment gradually deteriorate.
For example, in the author's "Tang-yin County New Village Planning" project, through previous research, it was found that none of 24 villages had typical formal professional planning.
