一米深度以下就可以不考虑温度日变化的影响。 - A diurnal temperature variation of-4k is present at 50km because heating only occurs during the day .
由于加热只发生在白天，因此50公里高度上的温度日变化约为4k。 - The daily and yearly temperature oscillations die away at depths less than 1m and 30m respectively .
温度日变化波及的深度小于1米，而温度年变化影响的深度约30米。 - Moreover, diurnal bias resulting from averaging observations made at only a few hours each day is often difficult to detect .
尤其是每天仅仅几次观测的平均所导致的日变化偏差常常是很难发现的。
