aeromechanics

The mathematical model of nonlinear time-varying system includes not only nonlinearity but also time-varying parameters. It has been extensively used in the field of aeromechanics, economy, medicine and construction, and so on.

非线性时变系统的数学模型既包含非线性项，又具有时变参数，是最具一般意义的动力学系统，广泛存在于航天、经济、医学、建筑等学科领域。

Scientific computing are involved in many important applications, such as aeromechanics, modern biomedicine, oil reservoir, environmental science, nuclear simulation. Matrix decomposition and inversion play the base and key role in scientific computing.

科学计算涉及到航空航天、现代生物与医学、石油勘探、环境科学、核模拟等国民经济和国防建设各个重要领域，矩阵分解、求逆的矩阵运算则是科学计算的基础和关键。
