摘　　要：讨论了用聚乙烯醇纤维制备活性炭纤维的碳化过程中，纤维成分、结晶形态及物理织构的变化，并指出了中空结构的形成过程和影响因素。获得较高得率的均匀活性炭纤维，应采用７℃／ｍ ｉｎ 较慢的升温速率。The changes in fiber component, crystalline morphology and physical fabric structure during the course of carbonization of polyvinylalcohol fiber that was used to prepare activated carbon fiber were discussed. The formation of the hollow structure and the influence factors were pointed out. In order to get the higher yield of uniform ACF, the temperature rising rate should be given as 7℃/min.
