When the sun zenith angle is small, a less angular sampling interval in zenith angle is needed in the hot spot area.

The results are as follows: ( 1) Solar incident angle, especially zenith angle can change the shape of BRDF.

具体研究结果如下：（1）太阳入射角度，特别是太阳天顶角能改变水体二向反射分布函数的形状。

G silicon carbide waterproof abrasive paper were made within the-15 °-55 ° of reflectance zenith angle.

G防水研磨金刚砂在反射天顶角-15°～55°范围进行了测试研究。

The results show that the detectable stellar magnitude limits linearly increase with observing height and solar zenith angle.

结果表明：可探测星等极限值随观测高度和太阳天顶角的增加接近线性增加；

Some results of high energy cosmic ray, such as the zenith angle distribution, the decay length in the air, the energy spectrum and the vertical intensity of hadron and γ-ray have been presented.

由此给出了天顶角分布、大气中衰减长度、积分能谱和垂向流强等，为研究宇宙线超高能相互作用提供了信息。

As expected, the measured brightness temperatures change with view zenith angle, view azimuth angle, and the Sun position.
