How to improve training records and skill level, and try to minimize sports injury at the same time, has increasingly become the focus of Volleyball Professional Training Design.
To sum up, it is essential to acquire volleyball athlete foot omni-directional pressure information, which quantitatively reveals the foot biological mechanics characteristics and kinetics characteristics when the volleyball athlete is running, jumping, kicking etc., thus to provide a scientific basis for Volleyball Professional Training Design that is in order to improve the athlete’s training records and skill level and minimize sports injury.
Besides, PVDF film is light, flexible, extremely thin, impact-resistant, invulnerable to the pollution of water and chemicals, and easily made into any shape and area ranging from tablets or tube[4].
In order to improve the athlete’s training records and skill level, and at the same time try to minimize sports injury, Volleyball Professional Training Design must take the scientific theoretical basis for guidance, and precise data acquisition must be premised.
Using this method can accurately acquire the static and dynamic distribution information of the volleyball athlete’s foot pressure, thus to provide data support for the research of the foot biological mechanics characteristics and kinetics characteristics when the volleyball athlete is running, jumping, kicking etc., and to provide scientific theoretical basis for Volleyball Professional Training Design.

Brick fragment was saturated with water to a degree usually corresponding to common humidity of uninsulated underground brickwork of historic buildings.
Presented results provide the professional public with basic orientation, specify estimate of drying time in comparison with already used estimate based on Cadierques relationship and provide stimulus for further research. 3.
Experiment Results Monitored parameter of performed tests was diffusion flow of water vapours, i.e. speed of transport of water vapours through surface finish of samples to the surrounding environment under above described conditions.
Results of diffusion flow of water vapours for individual treatments are visible from the following table 3.
Water vapour resistance factors of three wall surface finishing.

Defects on some of them and unfortunately even accidents of some cases of bridge objects, mainly recently published by media, related to corrosion of prestressed reinforcement awoke interest of both professional and wide non-professional public related to its durability.
Recent breakdowns of some bridge buildings related to reinforcement corrosion steered attention of mainly wider professional public towards points of issue of corrosion of prestressing reinforcement and at the same its anti-corrosion protection.
Defects and Breakdowns Important impulse that attracted attention of not only professional public to the issue of corrosion of steel prestressing strands appeared in relation to an unfortunate collapse of the footbridge in Prague – Troja, connecting Vltava river banks of Císařský island and Troja district.
Penetrating water in some cases also evidently migrated in the core or on the surface of wires of PSC strands, pouring down by gravitation in the direction of longitudinal slope of the bridge deck.
Humidity condition in ducts and slots of the footbridge in Troja was for sure affected by floods during which the footbridge twice fully disappeared under the water.

Along with the acceleration of the urbanization process and the continuous growth of population, the municipal water demand would be increased, added to water resource shortages, municipal water supply in Kashgar area is being serious in future.

It is demonstrated that the abundance degree of water resource system itself had a strong relevancy with water resource bearing capacity in Kashgar, the relationship between ecological environment and water resource environmental in arid area are very close, the circumstance of ecological environment had a direct impact on water resource bearing capacity. 2) In the water resource system, the availability and natural replenishment of water resource are key factors to water resource bearing capacity.
In the society, economy and ecological systems, the natural population growth and domestic water quota, the industrial and agricultural water consumption, Industrial waste water treatment success rate and biodiversity index are key impacting factors to the pressure of water resource . 3) The order of layer C demonstrated that the degree of water resource bearing capacity in Kashgar had a strongest relevancy with water resource and ecological system, the natural replenishment of water resource, the abundance degree water resource, the treatment toward the harm on water resource’s health from industrial water consumption, the land’s biodiversity are important factors for the water resource bearing capacity.

Priority Areas of China’s New Countryside Construction The three constraints on capacity development in the rural area: (i) declining land and water resources; (ii) lack of access to rural finance, infrastructure, technology, markets, and nonfarm income opportunities; and (iii) threat of climate change and volatility of food prices.
Littering, poor village streets and poor water disposal system are seen as the most pressing problems in terms of rural living conditions.
Major Paradigms Land degradation, loss of biodiversity and water drawdown has taken their toll on the poorest populations in rural areas.
Capacity development is fundamental to new countryside construction in terms of access to clean water, sustainable and affordable food and nutrition security, and poverty reduction through sustainable livelihoods and economic growth.
Provide results-based incentives for sustainable agricultural initiatives that are based on inter-institutional and inter-disciplinary collaboration and innovative linkages among research, extension, education and development professionals.

The role of purifier is filter, distill the deterioration transformer oil and a series of operations, remove impurities in transformer oil (water is mainly), making the index reach close to new oil standards.
(5) Connections of the into-out oil tube must be carried out under the command of professionals
The test results of the transformer oil is only 19.5kV which does not meet the national standard, and also water content of 89mg/kg.According to user needs, 7th December, 2013 to 8th December,2013, “oil purifier in line” is used to the transformer purifying for 15 hours.
After purifying, the results of testing the transformer oil shows that breakdown voltage reach 46kV and water content of 41mg/kg that complying with national standards.
