Secondly, by applying inverse Fourier integral transform to the displacement, and uniting the constitutive and geometrical equations, the analytical expression of stress in Laplace domain were derived. Thirdly, by defining dislocation density functions, the Cauchy singular integral equations were obtained according to the boundary condition and interface connection conditions, and the problem was reduced to algebraic equations by Chebyshev orthogonal polynomial. Based the these, the unknown coefficient of the algebraic equations can be solved by Schmidt method. Finally, the time response of dynamic stress intensity factor and energy release rate are obtained by inverse Laplace transform.

During the reaction of alkylation, general contained 0.2%~2.0% butadiene will produce viscous heavy composite materials, which will raise final boiling point of alkylate and decrease octane, what is more, it will react with acid to produce corresponding ester, which will increase the consumption of acid, Therefore, we must remove butadiene by selective hydrogenation, at the same time, it will convert some of 1- butane to 2- butane by isomerization and raise octane of alkylate.
一般含有0.2%~2.0%的丁二烯,其在烷基化反应中,可生成一种分子量很高的粘稠重质迭合物,使烷基化油的干点升高,辛烷值降低,并且它还和酸反应生成相应的酯而加大酸耗量。因此必须经过选择性加氢除掉丁二烯,同时,将部分1-丁烯异构化为2-丁烯,以提高烷基化油的辛烷值。
