And even in condition of tiny deformation, the concrete material is not perfect elastic but nonlinear.
即使在微小变形条件下，砼材料也具有非线性性质，不是理想的弹性材料。

T-S fuzzy control system based on asymptotic tracking control is designed for a MIMO nonlinear boiler-turbine system whose parameters vary under the operating condition within wide range.
The ship's floating condition calculation aims at obtaining three floating condition parameters. It can be attributed to solving an implicit nonlinear equation group.
