It is feasible in the technology and reasonable in the economy to take the mineral composition fiber as papermaking filler.

矿物复合纤维作为造纸填料技术上可行，经济上合理。

To add mineral composition fiber during the papermaking, the tensile strength of the paper will lower, has no effect to the paper sizing degree, and also has small effect to the paper brightness.

矿物复合纤维在造纸中应用后，纸张的强度有所降低，对纸张施胶度没有影响，对纸张光泽度的影响较小。

Secondly, study the factors that affect the operating performance of the mineral composition fiber, and the effect to the paper performance when add the mineral composition fiber in the laboratory.

其次，在实验室研究了影响矿物复合纤维应用性能的因素、添加矿物复合纤维对纸页性能的影响。

After analyzing optical brightening techniques used on the prints and scrutinizing the corporate logos and fiber composition of the paper, Mattis' team proved most of the photos could not have been made before the 1950s, long after Hine's death.
