m_pD3dDevice->SetRenderState( D3DRS_ALPHABLENDENABLE, TRUE);
m_pD3dDevice->SetRenderState( D3DRS_SRCBLEND, D3DBLEND_SRCALPHA   );   
m_pD3dDevice->SetRenderState( D3DRS_DESTBLEND, D3DBLEND_INVSRCALPHA   );

m_pD3dDevice->SetTextureStageState( 0, D3DTSS_ALPHAARG1, D3DTA_TEXTURE );
m_pD3dDevice->SetTextureStageState( 0, D3DTSS_ALPHAOP, D3DTOP_SELECTARG1 );

渲染之前加上如上面的代码应该可以
