Authors expound plastic formwork technology for open waffle slab of clean room in IC workshop systematically,and discuss the key problems in construction and controlling method.

Meanwhile, according to some key construction techniques, plastic formwork technique and bottom girder treatment skill detailed introduction is made.

One solution to the eigenstates of pairing Hamiltonian in shell model;

Studies on Dynamics of Turbulence with Shell Model and Stability of Spiral Waves in Reaction Diffusion Systems;

The shell model finite element methods are better than the simplified analytical cable model methods in simulating shell deformation properties of pipe for the response analysis of buried pipeline crossing fault;but the cable model methods are still used in the relevant guidelines in China and other countries.
