Experiments showed that according to substantial equilibrium,we can get a small range of COD by studying the changing disciplinarian,and it can be used to rational judgment end-point of flax retting.

对亚麻脱胶终点的定量判断进行了探讨，根据物量平衡原理，研究了脱胶过程中 COD值随时间变化的规律，得出脱胶终点时的 COD值范围，借此可作为一种定量判断亚麻脱胶终点的方法。

The high efficiency and high power semiconductor laser with multi-active regions which are cascaded by reverse biased tunnel junction has a higher inner quantum efficiency which can larger than 1, so that it can output higher optical power at the same injected current compared with the normal lasers, meanwhile, it can be designed to large coupled optical cavity, so it will increase the limit of the electro-thermal destroy and the COD.

通过反向偏置隧道结将多个有源区级联起来的多有源区耦合大光腔高效大功率半导体激光器从理论上解决了传统激光器存在的问题，由于其内量子效率大于1，可以在相同电流下输出高的光功率，且可以制成耦合大光腔结构，增大了光腔面积，因此相对于传统激光器而言，其电热烧毁和COD水平都会提高。

It shows that the removal rate of COD gets larger basically when the Reynold number and pressure get larger.

结果表明，COD去除率随Re数的增大而增大，随出口背压P的增加而增大，但气体流量的改变对COD的降解并无明显的影响。

We change the Reynold number, pressure, gas flux and liquid flux in the aeration test of wastewater respectively, and analyze their influence on the performance of the bioreactor by evaluating degradation of COD.

我很喜欢这带辣的鱼卵。。。

The experiment is began with the runoff quality on the diverse roofage and different grade roadway, the results are as follows:(1) The concentration of contamination is different with the diverse roofage, and SS value is also different with the style roof;(2) In the beginning , the concentration of COD value and SS value is higher ,but the runoff quality will be reduced to steady gradually along with the rainfall duration increase;(3) The city roadway runoff is worse than the roadway of university ,because the city roadway runoff involve vehicle n people and the sanitation and material of roadway;(4) Based on the analysis of rainwater quality , the paper provide the process of rainwater treatment for roof, roadway, and lawn.

对教学区内不同建筑物，及道路上的雨水径流水质进行监测，得出以下结论：(1)材料不同，径流雨水中污染物浓度不同，屋顶类型不同，径流雨水中SS浓度亦不同；(2)初期径流污染物浓度很高，随降雨历时的延长，COD和SS浓度逐渐下降并趋于稳定；(3)道路污染与路面材料、来往车辆、人员流动、路面卫生状况有关。市区道路相比校园内道路，水质较差；(4)对雨水水质分析基础上，分别对建筑屋顶、道路、绿地提出雨水利用的处理工艺。
