But factors such as low population intensity and low land productivity restrict the efficient demand for road transport.

但样本县因人口密度过小、耕地生产率低下等因素限制了对公路运输的有效需求。

The actual level of intensity depends on such factors as the physical layout, population density, and productive activities of a metropolis.

实际的强度水平取决于诸如大城市的物理布局、人口密度和生产活动之类的因素。

Being very high intensity, this focus induces a population inversion in the oxygen atoms, ensuring that there are more excited than non-excited atoms.

在高强度下，这种聚焦会使氧原子的粒子束反转，确保了激发的原子多于未被激发的原子。

Its deadliness was linked, among other things, to the weakness of buildings, the depth of the quake, the density of population, the fault and soil types, and the intensity of the shaking.
