概周期函数及其主要性质

概周期函数论是由Ｈ．Ｂｏｈｒ在本世纪二十年代初期创立的．作为一种结构性质，函数的概周期性可以说是函数的周期性的推广．随着现代科学技术的不断发展，对于函数的这一性质的研究已经在实际应用中越来越显示出它的重要意义，特别是在微分动力系统的研究中占有非常重要的地位．本文介绍概周期函数的概念，并推出一些重要的性质

Almost Periodic Function and Its Main Properties

Almost periodic function theory was founded by H.Bohr in early nineteen twenties. As a kind of structural property, almost periodicity of function is extension of periodicity of function. With increasing development of science and technology, research of almost periodicity of function is becoming more important in practice, especially in differential dynamical system. In this paper, we will introduce concept of almost periodic function and extended some important properites.
