摘要：

Recent measurements of the cosmic microwave background radiation by the Boomerang and Maxima experiments indicate that the universe is spatially flat. Here some simple back-of-the-envelope calculations are used to explain the result. The main result is a simple formula for the angular scale of the acoustic peak in terms of the standard cosmological parameters: 1 approximate to 193[1 + 3/5(1 - Ohm (0)) + 1/5(1 - h) + 1/35 Ohm (Lambda)].
