Let the technology do no harm to the social environment in the application process, and can fully play its role in order to make the necessary land-based sources of pollution source prevention.

因为生态技术的补充，在应用科技的过程中既不损害社会环境，又能充分的发挥作用，从而对陆源污染产生的源头方面进行必要的防治。

Since we dig out the root causes of land-based sources of pollution problems from the philosophical side, we should seek the solution from the philosophical.

既然从哲学层面挖掘出了陆源污染问题产生的根源，那就应该从哲学上寻求解决之道。

And the plant had a two-way transport function of PAHs, PAHs in rhizosphere soil and plant stem leaves related to a certain extent, their sources of pollution had similarities.

根际土壤与植物茎叶PAHs含量及组成在一定程度上存在相关，说明他们的污染来源有相似性。

Through flue gas monitoring, we can identify the key sources of pollution, at the same time monitoring the pollution sources real-time.

通过烟气监测还可以确定重点污染源并对污染源进行实时监控。

Fundamentally improving the quality of the river water not only need to cut off the external sources of pollution, but also address the problems of internal pollution from the sediment.

要从根本上改善河水水质，不仅要切断外部污染源，还必须解决水体底泥的内部污染问题。

NO x is about 2 times as much as SO 2. The source emission was main reason for air pollution in Beijing.

各高度SO2和NOx之间的关系有较好的一致性，NOx大约为SO2浓度的2倍或2倍以上；污染源排放是造成北京城市低层大气空气污染严重与否的主要原因之一；

Based on K-ε turbulence model, two ventilation patterns are discussed for researching hybrid ventilation models. The indoor 3D air temperature fields and the pollutant CO_2 concentration distribution are studied by CFD simulation in a room where pollutant source and centralized heat source are laid out.

为了研究多元通风的基本模式，基于K-ε模型、针对两种不同通风方案，对内设污染源和集中热源的房间内的三维温度场以及污染物CO2的浓度分布进行了数值模拟分析。

Sewage COD on-line monitoring instrument of so-and-so chemical fertilizer limited company in Xinjiang by way of illustration, this paper compared on-line monitoring datum with laboratory potassium dichromate determined datum, discusses comparison and analyses method of pollutant on-line monitoring.

以新疆某化肥有限公司污水COD在线监测仪为例，用在线监测数据与实验室重铬酸钾法测定数据进行比对分析，对污染源在线监测的比对分析方法进行探讨。

It is concluded that application of these methods is helpful to implement the total emission control planning schemes successfully, to control pollution effectively, and to ensure sustainable development of economy.

指出将B值法和平权后剩余环境容量分配法相结合确定各污染源的平权允许排放量将有助于总量控制规划方案的顺利实施，有效地控制污染，改善环境，使经济得以持续发展。

In this thesis, based on experiment model, by the way of the Fluent software the physical model and maths model of single-polluting heat source and multi-polluting heat sources in small room are established.
