We attempt to study the feasibility of cloud base height remote sensing by ground-based sky thermal infrared brightness temperature observation and quantitative effects of the aerosol layer on it. Using the Modtran4.0 model simulation, the variations of Tb with zenith angle of observation for different types of aerosol and different visibilities under clear and cloudy sky conditions were systematically investigated.

本文利用Modtran4.0模式比较系统地研究了不同强度和不同类型气溶胶情况下，晴空和各种云所形成的天空红外亮温Tb(Infrared Brightness Temperature)随地面观测天顶角的变化，从中发现利用Tb观测来遥感云底高度CBH的可行性，以及定量分析气溶胶层的影响。

Occurs at a separation of 1.14a0 between the nucleus at the center and nuclei at the apexes. Therefore the binding energy of 0.5202 a.u. for this structure has been got.

结果表明，当中心原子核与四个顶角原子核间距离为1.14a_0时，体系能量有一极小值-13.9106a.u。，从而得到其结合能为

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
