摘　　要：考虑了由3个方程组成的一阶拟线性对角型方程组.在边界条件中对角变量没有任何耦合关系的情况下,通过建立一类二阶拟线性双曲型方程组的局部精确边界能控性,得到了该类方程组的单侧精确边界能控性以及具有较少控制的双侧精确边界能控性.We consider the first order quasilinear hyperbolic systems of diagonal form which is composed of three e- quations. In the case that the diagonal variables are decoupled in the boundary conditions, by establishing the local exact boundary controllability for a kind of second order quasilinear hyperbolic systems, we obtain the one-sided lo- cal exact boundary controllability and two-sided local exact boundary controllability with less controls.
