摘要
运用Ｇｉｒｄｉｎｇ不等式和Ｆｅｆｆｅｒｍａｎ－Ｐｈｏｎｇ不等式，建立了一类具实主符征（可以具重特征）的线性偏微分算子的局部可解性．
By using the Garding inequality and Fefferman-Phong inequality, the author obtaines some sufficient conditions for local solvability of linear partial differential operators with real principal part which may have multiple characteristics.
