摘要：

Numerical simulations are performed of the gravitational collapse of a scalar field with a lambda phi(4) potential. Comparisons for the wall motion and stress-energy are made with the thin shell approximation. It is found that the thin shell approximation generally works well, especially for the motion of the wall. However, the approximation is not as good at late times as it is at early times.
