介绍了通过纤维细胞腔加填和原位复合法进行纤维细胞内加填技术的研究现状，从TiO-2，沉淀CaCO-3，BaSO-4的加填，以及磁性纸和隔热纸的制备等方面，对纤维细胞内加填改善纸张性能的技术进行了介绍。

The research progress of fiber lumen loading technology was introduced from fiber lumen loading and in-situ compound methods. The technologies of improving paper performance by fiber lumen loading were introduced from the aspects of titanium dioxide filling, precipitated chalk (PCC) filling, barium sulfate filling and the preparation of magnetized paper and sheathing paper.
