摘要：

We record the height of the crack surface as a function of position along one-dimensional cuts orthogonal to the crack for six different brittle materials. We find that the width w of this one-dimensional trace as a function of its length L behaves as w approximately L(zeta), where zeta = 0.87(7). This result is in agreement with recent conjectures of a universal roughness exponent-zeta for these materials.
