摘要：
We present a study of molecular dynamics at the sol-gel transition. Application of percolation and bond-fluctuation dynamics provides critical exponents for viscoelastic properties in a strong covalent gel and shows a complex non-exponential relaxation behaviour. The results are in good agreement with experimental findings and offer interesting pointers for discussions.
