The article below deals with the mechanism research of this kind of machine, describing the structure and principle ; theoretically analyzing the data to derive formula ; tentatively proposing theory of radial flow between parallel plates for future design ; pores arrangement, i. e., longitudinal pores are equally spaced, horizontal pores bore size is preferred unequal and rows distance can be either equal or not but generally smaller than pores distance, and rows shall be odd numbers and are arranged symmetrical from the center row and bore size reduces gradually from the center row
本文對氣墊機作了機理研究，描述了氣墊機的結構型式及工作原理，對氣墊機的主參數作了理論分析，根據平行平板間的徑向流動理論，建立了計算模型，導出了計算公式，可作為氣墊設計理論的依據；提出了氣孔布置的原則：縱向孔間距相等較好，橫向孔徑不等為佳，橫向孔排距可以相等，也可以不相等，但一般小於孔間距。氣孔排數應為奇數，由中心兩側呈對稱布置，孔徑由中心向兩旁逐漸減小。
