First, this paper presents three girders model with double cable planes which main girder and side girder is connected by rigid arms, analyzes the dynamic characteristic of Yonghe cable-stayed bridge and obtains its natural vibration modes (i.e., frequency, damping values and the mode shapes ) by ANLSIS structural analysis program and uses these parameters as dynamic dactylogram of the intact case of cable-stayed bridge. Using the passage of random as the ambient vibration ,the dynamic properties of Yonghe Bridge is measured and the modal parameter of its 15 years after is identified and used as dynamic dactylogram of the damaged case. By the finite element analysis and locale vibration test, damaged and undamaged modal parameter is analyzed and curvature mode shape, which is sensitive to damage state, is introduced as possible candidate for identifying and locating damage in the cable-stayed bridge. Selecting the branch of part measured point from modal parameter, this paper deduces the damaged index which can detect the possible damaged location of the cable-stayed bridge deck and identifies the damaged region and degree for Yonghe Bridge. For the purpose of structural condition monitoring in in-situ , from another viewpoint, this paper introduces the method called the best optimization vector to detect damaged location and degree. The accuracy and reliability of the method presented in this paper are demonstrated by static analysis and test and the healthy state of Yonghe Bridge can be evaluated.

Five typical coals of low-to-medium rank (Huolinhe brown coal, Majiata non-caking coal, Datong weakly caking coal, Huozhou gas coal, Lingshi fat coal) and their macerals are prepared. The molecular structure and the oxygen functional groups of the selected coals and their macerals are studied by means of the conventional coal properties analysis, chemical analysis and the advanced instrumental methods such as FTIR,XRIK 13C-NMR.N XPS. The molecular structure characteristics, regularities and the results are discussed. Additionally, the total oxygen content and distribution characteristics of different oxygen functional groups in the raw coals and their macerals are studied.

Swine enteropathogenic E. colis were rejuvenescenced and 6 of them were selected to prepare blood serum. We had tested the reactance of cross agglutination and agar diffusion between the strains and the blood serums. No. 300 and No. 343 were selected because they had highly cross reaction. To test superantigen of No.300 and No.343, the antigens made by both of them immunized piglets, and then we detected the serum 0D values with indirect ELISA. The OMP and PF of No. 300 and No. 343 were extracted for SDS—PAGE and westen-blotting.
