本文对一般的二阶线性椭圆型方程，在满足内部锥条件时，证明了其强极值原理。

In this paper, the strong extremal principles have been proved for second or der linear elliptic equations on the domain which satisfies an interior cone condition.

通过对可行域定义新的拟锥条件，给出相应同伦方程，并证明此同伦算法在此拟锥条件下具有全局收敛性。

We defined the new quasi-cone condition, established the homotopy equation and proved the global convergence of this homotopy method.

但这团雾气的的确确是由美国海军从秘鲁海岸起飞的超级大黄蜂所制造出来的，即一般所谓的“冲击领”或“蒸汽锥”，在某些大气条件下飞机在高速飞行时就会产生这种现象。

But this cloud created by a U.S. Navy Super Hornet off the Peruvian coast is known as a 'shock collar' or 'vapour cone', created in certain atmospheric conditions at high speeds.
