Through professional analysis, without affecting the safe operation of the boiler's output, it is suggested to remove two-stage impellers from the 1st high pressure feed-water pump from the7th boiler and the first stage impellers from the 2nd high pressure feed-water pump.
The parameters of the high pressure feed-water pump frequency conversion device are shown in table 1.
Practical Application The control target of high bad liquid level PID High-pressure feed-water pump’s opening degree while the difference between High-pressure feed-water pump’s export pressure and high bag high bag’s pressure controls High-pressure feed-water pump’s speed, which means when High-pressure feed-water pump runs in normal frequency way, it can only change High-pressure feed-water Pump’s opening degree to maintain a stable high bad liquid level.
High pressure water pump’s frequency conversion and frequency parameters are shown in table 2.
Summary High-pressure water pumps equipped with frequency conversion, improves the overall efficiency of water operation system through reducing throttling losses from boiler to damper and improve the effectiveness of water pump working in a low flow condition deviated from rated operation condition.

Currently, the Internet provides information to the audience of sports sites in the following major categories: Professional sports sites ( such as domestic famous Sharkwave site ), government websites ( such as the Olympic Games official website ), integrated media sites (LONDON, Sohu, Sina ), traditional media has its own website ( such as People's Daily website, Xinhuanet ) and some do not amount to anything personal website.
From the quantity, quality, timeliness, authority and audience attention in terms of sports information dissemination, and other professional categories Sharkwave sports sites, Sina and other integrated media sites and traditional media such as Xinhua website is the site leaders which provide sports information, and Sharkwave, Sina is more prominent [1].
Professional sports website, but its depth and breadth of information attracted a large number of users.
At the same time, some users who will act as the mass sports news information, because most people have not received formal training professional news media, little is known about the propagation of the network, and thus make some online editing manuscripts very difficult, nor throw with no.
So many users have complained that the Internet information more water, real to the enemy .

Introduction With the continuous development of electronic information technology, more and more new radar has been widely used in the modernization of national defense.At the same time, we upgrad the radar technique and system, improve the requirement on radar professional operation and maintenance personnel.
Therefore, we need to cultivate radar talent of professional knowledge, strong practical ability, who can be adapt to the new military revolution.

Introduction Professional diving decompression chamber is part of health insurance of the persons involved in deep water diving.
When are leaving the surface, the divers are introduced in the decompression chamber to establish a balance between the pressure developed in the deep water and the normal pressure at the surface without diving suit [1].
Finally based on chemical, structural and mechanical characteristics, it is assessing the quality of the weldable steel alloy mark P355NH to select the lots 2, 5, 6, 7 and 8 according to ABS standard for the construction of the decompression chamber for professionals divers.

GIS education has developed rapidly and has become a world phenomenon because more and more GIS related professional and technical personnel and related applications reach to the demand with the development GIS technology and industry and the apply, maintenance and application in various fields.
It is easier for the students to understand and memorize professional knowledge because GIS is essentially a electronic map system which has the features of spatial analysis, general management, mapping and other fast dynamic update of a large number of map information.
Especially the powerful GIS spatial analysis function which can simulate actual combat and realize the communion between the map and professional knowledge make students to broaden their horizons, develop their ability to innovate and to make their own unique insights.

Such as " How to determine criminal hiding place", the most likely criminal hiding place could be determined by using the area floating population, traffic database to map out the comparison chart of the population and traffic and to superimpose on the vegetation distribution, regional topographic maps and district map. (2) develop student’s “inquiry” learning approach and improve student’s professional quality.

The fiber cement industry provides products to lower-income segments, such as tiles and water tanks, low-cost and useful life assets that last longer than seventy years.
Such techniques are widely used in qualitative research in the social sciences, but are rarely used to understand the thinking of the professionals of the exact sciences and engineering, except as an auxiliary tool in the bibliometric research.
All professionals who discussed the asbestos did not address relevant issues related to sustainability and the environment.

In addition, the education on water environment and other issues has spread nationwide, more than 30,000 people took part in this education.
The main task of the committee is to coordinate more than 40 organizations and professional groups for environmental education to implement on environmental education.
It required to set up environmental professional and curriculum, train technical personnel."
Since then, Tsinghua University, Beijing University and other colleges and universities have established the environmental professional.
After the 1992 United Nations Conference on Environment, the " Ten Countermeasures on Environment and Development in China " was approved by the State Council [9].Article VIII of them pointed out that at all levels of education bureaus and relevant departments should attach importance to environmental education, increase public awareness and consciousness in environmental protection in primary and secondary schools and kindergartens; Efforts to run professional courses of Environmental protection in colleges.
