I'm trying to render a RenderTexture with camera, but the renderTexture' alpha value always 1.

The alpha value is going to be whatever you set your camera's Clear Color to be. If you set its alpha to 0, and the render target is RGBA, then it will be 0 by default. This is nothing to do with NGUI, and you should use Unity's forum for these questions.
