英文摘要	In the microgravity environment, liquid is usually adsorbed in corners or slots. Liquid accumulated in these regions is difficult to be removed and used. A mathematical model describing static profiles of the liquid accumulated in the corner of truncated-cone-shaped containers under microgravity is obtained through theoretical derivation in this paper. The profiles have two cases according to liquid's wettability and the angle of containers' corners. Once coordinates of an endpoint of the profile are known, the profile and volume of the liquid can be obtained using the Shooting method according to the mathematical model. Besides, if abscissa values of the endpoints are unknown, the profile of the liquid can also be obtained using the dichotomy method and shooting method when liquid volume is given. It is easier to use these methods than others proposed before and they can also be used to predict liquid's profiles in other conditions. Numerical simulation is performed with the volume of fluid method and the results are in good agreement with theoretical ones. Based on the mathematical model, the profile and volume of the liquid accumulated in the corner can be predicted accurately.
