The variation at the lower solar elevation is caused by the cosine response of the instrument.

而太阳高度角较低时此值的变化，主要由仪器的余弦响应所引起。

In terms of the total vertical profile exposed and the low elevation, Gale offers attractions similar to Mars' famous Valles Marineris, the largest canyon in the solar system.

从目前所能观察到的整体垂直剖面结构和低海拔的特点来看，盖尔陨坑的科研魅力与太阳系中最大的峡谷——著名的水手峡谷不相上下。

The model presented here only USES a digital elevation model (DEM) to compute direct solar radiation, time of irradiation and simply diffuse radiation.

本模型只需数字高程模型(dem)就可计算太阳直接辐射、日照时间和简化的散射辐射。
