论文摘要
已经调查了水上海洋各种气氛的可能性。我们已经考虑了h $ _2 $的气氛，他的气氛涉及到海洋上的n $ _2 $氛围。天体生物学的主要主题之一是估计可居住区。如果地球上有一个大气的海洋，那么即将推出的红外辐射将有一个上限，称为Komabayashi-ingersoll极限（Ki-limit）。该极限取决于大气的成分。我们使用了Nakajima等人采用的一维灰色辐射相关模型，研究了简单模型下的这种依赖性。 （1992）。带有表面温度（$ t_s $）的传出红外辐射（$ f_ {irout} $）显示出一些特殊的行为。研究了H $ _2 $，HE和N $ _2 $ h $ _2 $ o Vapor的示例。还有另一个限制称为Simpson-Nakajima限制（SN-LIMIT），主要由蒸气组成。该蒸汽极限不取决于背景大气成分。在超级地球情况下（$ g = 2 \ times $ 9.8 m/s $^2 $），还计算了几种情况。提出了对初始压力的Ki-limit依赖性。研究了Koll＆Cronin（2019）的各种排放率。
It has been investigated the possibility of the various atmospheres over water oceans. We have considered the H$_2$ atmosphere and He atmosphere concerning to N$_2$ atmosphere over oceans. One of the main subjects in astrobiology is to estimate the habitable zone. If there is an ocean on the planet with an atmosphere, there is an upper limit to the outgoing infrared radiation called the Komabayashi-Ingersoll limit (KI-limit). This limit depends on the components of the atmospheres. We have investigated this dependence under the simple model, using the one-dimensional gray radiative-convective equilibrium model adopted by Nakajima et al. (1992). The outgoing infrared radiation ($F_{IRout}$) with the surface temperature ($T_s$) has shown some peculiar behavior. The examples for H$_2$, He, and N$_2$ background gas for H$_2$O vapour are investigated. There is another limit called the Simpson-Nakajima limit (SN-limit) mainly composed of vapour. This steam limit does not depend on the background atmosphere components. Under super-Earth case ($g=2\times$9.8 m/s$^2$), several cases are also calculated. The KI-limit dependence on the initial pressure is presented. The various emission rates by Koll & Cronin (2019) are investigated.
