基于示踪气体测量对房屋内空气渗透率的估计通常假设房屋是一个单一的完美混合室，在该混合室中，进入的空气瞬时且均匀地扩散到室内的所有部分。事实上，房子的某些部分--地下室或关着门的房间--与其他部分交换空气的速度非常慢，因此实际的混合远非瞬间。本文介绍了将示踪气体方法应用于多个房间的建筑物所需的理论和数学。
Estimates of air infiltration in houses based on tracer gas measurements have usually assumed the house to be a single perfect mixing chamber in which incoming air is instantaneously and uniformly diffused to all parts of the interior. In fact, some parts of the house—the basement or rooms with doors closed—exchange air only very slowly with other parts so that actual mixing is far from instantaneous. This paper presents the theory and mathematics necessary to apply the tracer gas method to buildings of many chambers.
