查询词典 practical unit

It"s considered that the algae blooms control function in the algae"s growth dynamics model is influenced mostly by the water temperature, sun illumination, water flow speed and the concentration of the nutriment in water. A function including the four elements was built. By using cell mapping algorithm and contacting with the practical water condition of the Wujiang river and the Hanjiang river we analyzed and computed the algae blooms in the two areas and found the result was very near to the practical result. And we found that the ascend of water temperature and the descend of the water flow speed will contribute to the growth of algae and the nutriment is the substance basis of the algae blooms but not the only element. It must be under the condition of condign water temperature, enough sun illumination, slow water flow and abundant nutriment that algae blooms may break out unexpectedly.

本文认为藻类生长营养动力学模型中的水华爆发控制函数主要受水温、光照强度、水流速和营养盐浓度的影响，构建了包含水温、光照强度、水流速和营养盐浓度的水华爆发控制函数，通过对乌江、汉江的水华爆发进行胞映射分析，得到的计算结果与实际监测非常吻合，并认为水温升高和水流速下降将有利于藻类生长，营养盐是水华爆发的物质基础，但不是唯一因素，必须在适宜的水温、光照、缓慢的水流和充足的营养盐条件下，藻类才可能出现突发式的"疯长"，即水华爆发。

But above research were all based on network whose parameters and topology structure were determinate. Network system in practical circumstance often presents randomicity because of influence of some factors. So it often causes some errors when apply traditional network flow theory to practical problems. It is significant for improving network flow theory's practicability to optimize network flow in stochastic circumstance. This question has drawn attention.

但以上研究都是在网络参数和拓扑结构固定的网络上进行的优化，而实际环境中的网络系统受多种因素影响往往会表现出随机性，所以传统网络流理论在具体应用时与实际情况会有一定的偏差，如果能在随机环境下对网络流进行优化，对提高网络流理论的实用性和针对性均有重要意义，这个问题已越来越引起关注。
