我们从希格斯场的非均匀初始数据开始，数值模拟了早期宇宙的暴涨时代的开始。我们的计算机程序是完全广义相对论的，包括希格斯场的引力效应，并模拟了一个空间方向上的时空不均匀。根据我们的结果，如果势具有正确的形状，希格斯场的大初始涨落并不能防止暴胀。在Coleman-Weinberg型模型中，对λ近似实现了Sigma=0.1m/subPl/膨胀。<；10/sup-2/，对于lambdaApprox，Sigma=0.01m/subPl/。<；10/sup-5/。.AE
We have simulated the onset of the inflationary era of the early Universe numerically, starting with inhomogeneous initial data for the Higgs field. Our computer code is fully general relativistic, including the gravitational effect of the Higgs field, and simulates a spacetime inhomogeneous in one space direction. According to our results, large initial fluctuations of the Higgs field do not prevent inflation, if the potential has the right shape. In a Coleman-Weinberg-type model with sigma = 0.1m/sub Pl/ inflation is realized for lambdaapprox. <10/sup -2/ and with sigma = 0.01m/sub Pl/ for lambdaapprox. <10/sup -5/. .AE
