The Study on the Calculation method of energy savings of Heating System in China Yimin Liu 1,a,Dan Yu 2,b 1School of Metallurgical and Ecological Engineering, University of Science and Technology Beijing, China 2Environmental and Energy Engineering Institute, Beijing University of Civil Engineering and Architecture, China atsxqlym@163.com,bcaoy@cabr-cecc.com Keywords: Energy savings; calculation method; The heating degree day method; Abstract.
If the actual engineering use this method, Uncertainty analysis and calibration must be carried out. 2.1 Uncertainty Analysis During modeling, we will use statistical analysis software, such as SPSS, SAS, etc., during the basical model forecast, in order to ensure the deviation between the prediction model and actual value to a minimum, which is to ensure that the model residuals is 0, between the predicted value and the actual value will produce a certain deviation, such deviation is the cause of the uncertainty.

Effect of polymer content to mechanical properties of fly ash slurry Yuezhong LIN Shandong Provincial Key Laboratory of Civil Engineering Disaster Prevention and Mitigation (Shandong University of Science and Technology) Qingdao China 266510 jcssust@163.com Keywords： Polymer content Fly ash cement fluid Mechanical property Abstract: In this paper, different polymer dosage in case of mechanical properties of fly ash slurry, through testing studies have shown that low-dosage strength of fly ash slurry has increased the role of high-dosage resulting in lower intensity, but the overall pressure off than reduced, improving the flexibility of fly ash cement, is it has a certain flexibility.
Excellent performance makes the polymer slurry in engineering more widely.
However, the different characteristics of the polymer slurry engineering performance requirements are very different, so the correct choice of polymer powder dosage is very important.
The pilot testing of different dosage modifier in the water slurry of the performance indicators, systematically mastered the latex powder content on properties of the influence of the slurry, the polymer latex powder in engineering applications to provide better reference.
