Goal compound synthesis namely: Take the vanillic acid as outset raw material, obtains 4- hydroxyl - 3- anisole methyl formate with the methyl alcohol reflux conditions, then after the etherification, the nitration, the return to original state, the ring closure response obtains 6- methoxy - 7- animal pen oxygen radical kui zuo lin - 4- alkone, then passes through the chlorination, the substitution aniline, to escape responses again and so on animal pen oxygen radical, etherification to obtain the goal compound; The goal compound and the diethylamine had the amine substitution reaction to obtain TM1, namely 4- benzene amino - 6- methoxy - 7- [2- hydroxyl - 3-(N, N- two ethyl aminos) third oxygen radical] kui zuo lin; Through zuo has the etherification with the Austria niter to respond obtains TM2, namely 4- benzene amino - 6- methoxy - 7- [2- hydroxyl - 3-(2- methyl - 5- nitryl imidazole) third oxygen radical] kui zuo lin.

In this paper, a general, strain-consistent, third-order displacement field of shells is proposed. On this basis, the nonlinear theory of composite laminated shells including third-order transverse shear deformation and rotary inertia is developed. Hamilton's variational principle is used to derive the nonlinear static and dynamic governing differential equations and the corresponding boundary conditions of composite laminated anisotropic general shells under the orthogonal curvilinear coordinates. And the form of spherical shells is degenerated.
