拟线性方程 meaning in English
quasi linear equation
quasilinear equation
Examples
- Comparing to linear equtions and quasilinear equations without degeneracy , such equations , to a certain extent , reflect even more exactly the physical reality . therefore , studying the optimal control problem of such equation is more important for practical use
与线性方程和不具退化性的拟线性方程相比，这类方程更能反映某些物理实际，因此研究由这类方程支配系统的最优控制问题更具有现实意义。 - Abstract : the purpose of this paper is to investigate the decay behavior and dynamics of a quasilinear partial differential equations with nonlocal boundary conditions which is motivated by model problems , arising from quasi - state thermoelasticity , etc . . by constructing an upper solution of the problem , a decay estimate for the solution is obtained
