Project zenith Angle and beacon wavelength have much influence on the angular separation.

发射天顶角越大，角间距越大。

The reverse time of the crest motion depends on the smallest zenith Angle and on solar cycle.

运动的反向时间随太阳的最小天顶角的大小而变化，随太阳活动而变化。

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

地面亮度温度的测量值随观测天顶角、方位角和太阳位置而改变。

Worm gears are adopted for driving rotational motion along azimuth Angle and power screws are used for raising zenith Angle.

蜗轮与蜗杆被用来驱动方位角的转轴，仰角的转动则使用螺杆。

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；
