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.

The phase equilibrium data of SBO-FAME-Methanol, SBO-FAEE-Ethanol and Glycerol-FAEE-Ethanol systems were measured. The results indicated that it involved two different stages: liquid-liquid-solid reaction stage and liquid-solid reaction stage. When the molar ratio of methanol to oil is 12:1 at 65℃, the turning point is at a 55% biodiesel yield. The liquid-liquid-solid reaction model was proposed based on the double-membranes theory. It indicated that the process is reaction and mass transfer controlled together at the first stage, and the second stage is reaction controlled. The predictions of the model are matched with the experimental results.In the end, the acid was extracted using methanol and ethanol from jatropha curcas l oil.
