It is pointed out that deformation of the surrounding rock has the characters of time pertinence and space pertinence. 結果顯示隧道開(kāi)挖后圍巖的變形具有時(shí)間相關(guān)性和空間相關(guān)性。
It is also concluded that so far as multipath scattering is nonisotropic, the spatial correlation will acutely rises along with increasing of LOS power. 只要多徑散射是各向異性的，空間相關(guān)性將隨直射分量功率增大而急劇增加。
