Energy Consumer Demand Predict of Hebei Province in the Domain of Low-carbon Economy---- Analysis Based on Gray Model GM (1,1) Juqin Wang1, Baolin Li2 1Department of NCEP University of Baoding, Baoding, Hebei Province, China 2Department of NCEP University of Baoding, Baoding, Hebei Province, China ice_0613@126.com Keywords: Low-carbon economy; energy consumption of Hebei Province; GM (1,1) model Abstract.
In this background, based on energy consumption situation in Hebei Province,we use GM (1,1) gray prediction model to predict Hebei Province’s energy consumption and energy consumption structure in 2003-2010.

Part I, P/M parts were prepared by distaloy HP powder that made by högöanas Sweden company (The chemical composition of this powder is shown in Tab.1).
The density of these parts is 7.65 gr/cm3, The obtained result shows less than 1% content of porosity that shows the effect of forging on reduction of pores.

The schematic diagram of microwave-assisted sintering setup used in this study is shown in Fig. 1(a).
For the reinforcement material, Si3N4 powder with an average particle size < 1 µm obtained from Sigma Aldrich was used.
The blended powders were weighed approximately 1 g using a weighing balance for each green compact pellet form.
