With the rapid development of China 's iron and steel industry, the domestic iron ore resources become increasingly scarce, and the supply of raw materials for iron and steel industry becomes increasingly tense, while the iron in the sulfuric acid residue is generally 30% to 50%, which can be used as a secondary resource [2-5], but most of the burning residue is in stockpiling for a long term.
The chemical composition of raw material was determined using X-ray fluorescence.
The anthracite dosage accounted for 10% of the raw material quality is appropriate.

Experimental Procedure The raw element materials with purity higher than 99.5% were mixed with the compositions of Nd8Pr2Fe79-xCo5B6Alx (x=0, 1, 2, 3).
The usual phases of Nd2Fe14B, NdFe4B4 and Nd-rich material are all visible.
The Nd-rich material exists mostly at the triple points as discreet areas.

On the one hand, due to the long age of construction of the ancient building, it is different in construction technology and materials to modern architecture.
On the other hand, many ancient buildings lack of basic data materials and have no drawings to query.
The essence of analogy method is to use historical earthquake materials to statistic damage percentage of typical building in different earthquake intensity.
In history materials, the description of earthquake damage often uses the language forms, such as intact, slight damage, medium damage, serious damage and collapsing.
