摘要：

We present an analysis of the critical behavior of viscosity and elastic modulus during the gelation of silica particles. Two systems are studied: gelation in NaCl solutions and in pure water. The experiments show a cross-over between entropic elasticity near the gelation threshold and 'mechanical' elasticity farther from it.
