As can be seen from the graph case 1 amplitude was significantly greater than the case 2 and case 3, the maximum acceleration peak value of ground surface acceleration values for the case 1 is 0.814 m/s2 Conclusion Based on the Newmark-β step time integration method, using dynamic finite element analysis theory, this paper analyzes in detail and discusses free field response of stress and deformation under the horizontal earthquake considering material nonlinearity and geometric nonlinearity.

From the gas phase spectra can be seen, retention parameters from the retained polymer surfactant A dry powder and water to confect polymer surfactant A extraction of material value and retention time and solvent and retention time is basically the same.Therefore,there is no organics in polymer surfactant, or organic pollutant concentration is too low, below the instrument detection limit, and therefore are not detected.
