<正> Various rinds of fractal objects have been widely studied, since the first Benoit B. Mandelbrot introduced "fractal" into geography in the 1970's. The most of these studying are macro-graphic, fractal geometric examples in micro-scopic field are fewer. In the present paper, we not only observe a true fractal grown interface in LiNbO_3 crystal, but also found that the etch pit pattern on axial c surface of LiNbO_3 crystal demonstrate all the geometric characters of Sierpinski gasket (as shown in Figl to Fig4). And the fractal
