这是一种可以测量纸浆中纤维粗糙度（单位长度重量）的方法 通过在已知长度的准备好的滑道上计算每单位面积上已知重量纤维的交叉点来确定。通过显微镜和机械台，将载玻片穿过一系列5厘米的距离，对交叉点进行计数。如果还需要根据TAPPI T 232测定样品中纤维的长度 “投影法测定纸浆纤维长度”，如T 232所述，当纤维图像投影到屏幕上时，可以计算已知等效长度线上的纤维交叉数，而不是使用显微镜。

This is a method by which the coarseness (weight per unit length) of the fibers in a pulp may be ascertained by counting the crossings of a known weight of fibers per unit area on a prepared slide over lines of known length. The crossings are counted with a microscope and mechanical stage, by traversing the slide over a series of 5-cm distances.If it is also required to determine the length of the fibers in a sample in accordance with TAPPI T 232 "Fiber Length of Pulp by Projection," instead of using a microscope, the fiber crossings over lines of known equivalent length may be counted when the images of the fibers are projected on a screen as described in T 232.
