我们提出了一种形式来计算在有限温度下使用高斯滤波器在某些空间尺度上粗粒度标量场的概率分布函数。作为一个应用，我们研究了最小标准模型中亚临界波动在电弱相变中的作用。结论是宇宙已经达到临界温度，处于真真空和假真空的混合状态。
We present a formalism to calculate the probability distribution function of a scalar field coarsegrained over some spatial scales with a Gaussian filter at finite temperature. As an application, we investigate the role of subcritical fluctuations in the electroweak phase transition in the minimal standard model. It is concluded that the universe was in a mixed state of true and false vacua already at the critical temperature.
