Finally, the effect of the complete recycling use of distilled effluent on ethanol fermentation was examined in order to save the cost for the treatment of waste distillage and promote cleansing production. Based on the data of 13 circulations, although the average fermentation time needed to be extended to 30~40 hours, over 12.5% ethanol was achieved, at the same time, residual reducing sugar and total sugar were maintained below 0.70% and 0.90%, which indicates that the negative effect of the completely recycling use of waste distillage was limited, and the waste distillage can be completely recycled within the fermentation system.

在此基础上，从减轻废糟液处理负荷，实现清洁生产的需要出发，进行了无种子罐条件下酒精蒸馏废液直接全循环使用的自絮凝颗粒酵母酒精连续发酵实验研究，十三次全循环运行得到的实验数据，与无废液循环的实验结果相比，虽然平均发酵时间略增至30h～40h，但发酵终点酒精浓度仍达到12.5％以上，残还原糖和残总糖分别在0.70％和0.90％以下，说明循环积累物对发酵的影响有限，废糟液直接全循环使用的工艺技术路线可行。

The periostea of both experimental and control side of the mandibular ramus were taken and prepared, 2 of each 5 rabbits in a group were prepared for HE stain detection and 3 for proliferating cell nuclear antigen immunohistochemical detection.Results:1, The newly formed bone was detected on the lateral aspect of mandibular ramus after periosteal distraction. The bone was shaped like a hill. It looked very low and was full of holes at postoperative day 28. With the time of consolidation period lengthened, the newly formed bone matured gradually. X-ray examination showed the new bone shaped like a hill. The average values of new bone height at postoperative days 28,35,42 and 56 were 1.86 + 0.15mm, 2.29 + 0.29mm,3.19 + 0.13mm and 4.70 + 0.45mm. Histological examination of both HE stain and picricacid-fuchsin stain showed the increase in the number of osteoblasts and the change in the orientation of collagen fibers and bone trabecula. There were no significant differences between newly formed bone and original bone on the lateral aspect of mandibular ramus at postoperative day 56 histologically.2 Compared with the control side, the distracted periostea proliferated obviously under the microscope, and the number of periostealcells increased with satiation of cellular nuclear per unit area. The images of PCNA immunohistochemical stain of periosteum showed that the experimental periosteum proliferated obviously after distraction compared with the control side.
