论文摘要
本文包含一个新概念，可以测量双曲机平面中凸体的宽度和厚度。我们将已知概念与新概念进行比较，并证明了恒定宽度，直径恒定和厚度的身体。
This paper contains a new concept to measure the width and thickness of a convex body in the hyperbolic plane. We compare the known concepts with the new one and prove some results on bodies of constant width, constant diameter and given thickness.
