Only a small quantity of phloem fibers were distributed in the secondary phloem, and the phloem ray was unconspicuous. 次生韧皮中分布有少量韧皮纤维,韧皮射线不明显。
The pulp yield of different processes was affected by the deliberating ratio.Higher pulp yield represents poor deliberation of the fibers. 不同制浆法之纸浆收率受解纤率之影响,高收率系由于韧皮纤维解纤不良所致。
