UV-Vis and continuous variation plot method were used to study the complexation of γ-cyclodextrin with bromocresol green, and the stoichiometric ratio of the complexation was to be 1∶2. Thermodynamic analysis results show an inverse relationship between temperature and complexation constant, and the change of enthalpy, entropy and free energy of the complexation were -39.988 kJ/mol, 86.400 J/ and -14.245 kJ/mol, respectively, which indicating that hydrophobic effect was the main force to form the complexes.γ-Cyclodextrin and bromocresol green complexes were examined by nuclear magnetic resonance, infrared spectrum and molecular modeling analysis, and was may be the group included in γ-cyclodextrin.

According to by the time series estimate power spectral density\'s periodogram law principle,the research adopts five level of orbital power spectra which US Federal railway Administrative bureau FRA proposed;then,through the Fourier inverse transformation,the orbital not smooth time domain samples are obtained, which determine the track irregularity peak-to-peak value and the corresponding wave length; on the basis of the research,the influence of the wheel track dynamic contact force are considered.Based on the orbital roadbed coefficient\'s definition,computation model is established to solve the roadbed equispaced spring constant,and the roadbed uniform spring stiffness is obtained by using the numerical simulation method.Finally,based on the Matlab procedure platform,the computational procedure is established,and the load time interval caused by the moving train acts on the roadbed is obtained.
