In regulation works of mountainous channel , determination of designed lowest navigable water level of reach with fluctuating backwater area is a common problem 摘要变动回水区河段设计最低通航水位确定是目前山区航道整治工程中经常遇到的问题。
The paper points out that the reduction in do oxygen along the river were the major factors in fluencing water quality and backwater reservoir ecosystem 指出溶解氧沿河道下游沿程逐渐减小，复氧系数降低，是引起水质恶化，破坏库湾生态平衡的主要因素。
With the monitoring , the paper demonstrated changes of the water environment in xiangxi river backwater reservoir after the building up of three gorges dam 摘要通过监测论证三峡建库后形成香溪河回水库湾水环境条件改变特徵，评价表明水质由轻污染至重污染趋势发展。
Even e - backwaters such as turkmenistan or myanmar provide things like visa application forms on the web , although in other respects they may be invisible online 甚至电子时代的死角例如土库曼斯坦或者缅甸也在网上提供类似签证申请表之类的东西，尽管其他人认为他们不可能在网上显示。
In the first two missions of the game , you ' ll storm the beaches of normandy and attempt to guide a group of paratroopers through the backwaters of france in support of the d - day invasion 在游戏的最初两关中，你将席卷诺曼底滩头并试图带领一股伞兵穿越法国的洼水区以支援d日的登陆。
The average temperature of supply water and backwater only is single function of extraventricular temperature . so only it can reflect radiator ' s emitting heat , heat net supplying heat and user ' s heat load 只有二次网供回水平均温度是室外温度的单值函数，即它能反映用户热负荷、散热器散热量、热网供热量的大小。
The article gives us a method to improve the quality of steam ; such as reducing and disusing the backwater of sugar producing in producing steam , adoping indirect heating method , and disaffiliating sugar producing 改善蒸汽品质提高酒精质量的方法：减少或不用制糖回水来生产蒸汽；不与制糖生产同步；采用间接加热。
