摘 要:利用微分几何学的知识建立了一种登机模型,模型主要研究一般关系的时空.它是一个机制模型,可以用来获得解析解.使用米制单位描述登机过程.乘客在登机时的妨碍关系产生了时空中自然的偏序,登机时间与最长的偏序链的大小一致.We established an airplane boarding model with differential geometry, which is used to lime the space-time of general relativity. Our model is a mechanism model by which we can get the analytic solutions. We introduced the metric space-time to describe the process of airplane boarding. The blocking relationships between two passengers can be considered as the longest chain in a peeling process which coincides with the causal relationships in the spacetime.
