The selection workings of the space-mission experiments on the International Space Station Project have been run with drop towers and parabolic fight airplanes in many related countries. We have studied the separation processes in the space with a tower and an airplane. The separation processes in a HPLC (high performance liquid chromatography) are phenomena in a reaction-diffusion-flow system and the experimental conditions must be empirically determined to control the processes because many and complex factor are related to them. But we can treat the processes as non-equilibrium and chemical phenomena running under an open condition from viewpoint of gap from a ideal condition. We have had experiments of the pattern dynamics in a TLC (thin layer chromatography) under a micro-gravity in a free-fall facility at JAMIC (Japan Microgravity Center, Kamisunagawa, Hokkaido). The principle of a TLC is as same as that of a HPLC essentially. The rate of the explosion increases as it is under a microgravity and decreases as under overgravity. These are as same as those expected before the experiment and it demonstrates that the expansion in a TLC runs against a gravity.

国际空间站项目的太空任务实验的选择工作在许多相关国家都是用落塔和抛物面战斗机进行的。研究了塔与飞机在空间的分离过程。高效液相色谱（HPLC）的分离过程是一个反应-扩散-流动体系中的现象，涉及的因素很多，复杂，必须凭经验确定实验条件来控制分离过程。但我们可以从理想状态出发，用能隙的观点把这些过程看作是非平衡的、开放条件下的化学现象。我们在日本微重力中心（日本微重力中心，上砂川，北海道）的自由落体装置中进行了微重力下薄层色谱（TLC）中图案动力学的实验。TLC的原理与HPLC基本相同。在微重力状态下，爆炸速率增加，在超重力状态下，爆炸速率降低。这些与实验前预期的相同，并且表明TLC中的膨胀与重力相反。
