For example, by posting signs in the dormitory, restaurant, washroom and other places to strengthen students' awareness of saving water and electricity resources, reduce food waste.
College students are the leading social group of new technology and new ideas, the senior professionals of national training.

Before the construction quality control 1.1 The selection criteria of the construction unit Unbonded prestressed concrete construction is very professional, the requirement of technology and the operation is very high, according to the provisions of the relevant provisions of Technical regulation of unbonded prestressed concrete structures(JGJ/T92-93)[2] and Construction technology policy [3],should entrust construction unit that have related level of qualification to construct. 1.2 Do the technical clarificaiton work seriously 1.
Corrosion-resistant and lubricating grease Should have good chemical stability in -20℃~+70℃ temperature range, in high temperature does not flow, no fission no crisp at low temperature, has a certain toughness, has no erosion influence to the surrounding materials, can prevent water, damp proof, resistant to corrosion, have good lubrication performance, reduce the friction resistance effectively. 3.
Conclusion The prestressed concrete construction is a very professional job, have a high requirement to the construction materials, equipment, the construction technology, construction personnel technical level, so its have certain difficulty to guarantee construction quality.

With the development requirements of modern water transport, constitutes a form of jobs moving from labor-intensive to technology management type changes.
Study of the human resource of waterway system Through the research on long-term work in the channel system talent expert interview, combined with the author's many years of work experience, clear an ideal professional and technical personnel with ability quality factors, build human resources evaluation system, as shown in Table 1.
To ensure the randomness of the sample and to avoid errors caused by small sample, we make anonymous questionnaire survey between the Yangtze River Waterway Bureau belongs grassroots units and professional and technical personnel, a total of 200, finishing the last 189 valid questionnaires survey data.

With every new video, the audience intently, suddenly their mouth spray water column on the screen, this is an exciting time.
The combination of modern design and architectural innovation has been proven to be a successful art form, a new culture of communication for artists, cultural professionals, arts organizations, cultural institutions, government agencies, enterprises, and all the media, the public, and increased , public interaction space.

Using computer-aided design work can via the Internet more effectively coordinated with architects, also structural engineers, as well as water, electricity, roads and other professionals work closely with the garden project designer, in a large engineering requirements.

Furthermore, because all low-strain analysis software available thus far includes defects, judgment accuracy is still based on the experience of technical professionals.

., Ltd 2 Tianjin professional college 3Tianjin Lintaike Technology Co.
The mobile phase consisted of methanol, water and acetic acid (60:40:1, v/v/v) and was pumped at a flow rate of 1.0 mL/min.
Water was purified in a Milli-Q system (Millipore, Bedford, MA).
Mixtures of methanol water and acetic acid were examined as the mobile phase and its composition was optimized.
The ratio of methanol, water, acetic acid was was 60:40:1 This ratio obtained a good resolution of Hypocrellin A and B.

Case study Wahaha's IS Resources Combination In terms of IS human capital, Wahaha has formed an IS human capital team leaded by doctors, comprised by over 30 professional technicians.
In the implementation of enterprise resource planning, Wahaha follow the order of arrangement: water plant first, milk factory follow-up.
In the implementation of enterprise resource planning of the milk factory, solutions for dairy products are different from the aquatic solutions, Therefore, the relevant skills and experience of aquatic project can not be directly transplanted to the milk products project, Wahaha information center staff was learning by doing, and gained relevant experience from the water plant project, and ultimately completed the project successfully.
This pattern: compared with buying patterns, can form a good relationship with our suppliers and rely on this relationship to obtain a high level of professional service, compared with the preferred contractor, can reduce the cost paid for the solution and the transaction cost arising with the formation of the solution, compared with the contracting-out model, both has the relative advantages of the buying patterns and the preferred contractor model.

There are various environmental factors that can cause reinforcement corrosion mainly including natural environment (for example, moist air, underground water containing corrosive medium etc) and acid, alkali and salt corrosion in industrial production.
The value of data is larger as a whole and the reason is that, corrosion rate of abutment under seriously humid environment with water-logging is greater than that under dry area; It is also found from Figure 3 (a) that: actual measurement result by using impulse current method is generally larger than that by using linear polarization method, which shows that linear polarization method is more precise than impulse current method, and the data difference shows the testing deviation between these two testing methods; while the approximate data also reflects the scientific nature and reliability of testing data.
