排放

Currently, exhaust gas recirculation is one of the most effective measures to reduce NO〓 emissions from diesel engines.

目前，降低柴油机NO〓排放的最有效措施之一就是废气再循环技术。

The CO2 uptake rate of plants is affected by the plant species and environmental conditions such as photosynthetically active radiation, temperature, water and nutrient contents. PAR is the most immediate environmental control on photosynthesis while air temperature affects both photorespiration and dark respiration. In the natural condition, PAR and temperature play an important role in net CO2 uptake. The effects of PAR and air temperature on the CO2 uptake of Pterocarpus macrocarpus grown in a natural habitat were studied in the present work. Due to many uncontrollable factors, a simple rectangular hyperbola could not represent the measured data. The data were divided into groups of 2℃ intervals; CO2 uptake in each group may then be related to PAR by a rectangular hyperbola function. Using the obtained functions, the effect of PAR was removed from the original data.

用涡度相关法对亚热带红壤丘陵区人工针叶林的二氧化碳、水、热通量进行了观测，重点分析了23m、39m两层高度的观测结果，同时把观测期分为春季和冬季两个不同时间段作了对比：结果表明，不管冬季还是春季，39m高度所测的总通量值和夜间通量值都要小于23m的观测值，这种通量差别表明：23m高度的观测结果更接近当地生态系统与大气之间的通量交换值，在此种生态类型条件下用涡度相关法测碳通量时，在23m、39m两层高度之间仍然存在大气平流现象；该试验区植被在冬季仍然可以进行光合作用，而且光合作用所吸收的CO2大于呼吸作用所排放的CO2，因此该种生态系统在冬季仍表现为碳汇；春季的碳通量值为冬季的2倍以上。

An increase in analytical and methodological work is also expected, particularly in the area of land-use change and REDD.

预计分析性和方法性工作也会增加，特别是在土地利用的改变和减少因毁林和森林退化而造成的排放等方面。

But it will take more than financial incentives alone for REDD to lower emissions and improve livelihoods.

但是这将需要REDD不仅仅采用财政激励措施去降低排放和改善生计。

If the ecosan would be developed there, new industries could be promoted and 50-100 thousands of employing opportunities could be created, incidence rate of diseases could be reduced, 560 thousand cubic meters of methane could be recycled, investment of sanitary toilet could be reduced to an acceptable price, i.e., 600-750 RMB yuan per house, ecological agriculture could be developed, and pollutants discharge could be reduced while ecological security could be guaranteed.

若在该区域推广生态卫生，可能产生社会、经济及环境效益如下：带动新兴产业，增加5~10万的直接就业机会；降低疾病感染率；回收沼气56万立方公尺；卫生厕所投入控制在可接受的600~750元户^(-1)；促进生态农业循环；降低污染物排放、保障生态安全。

The biggest benefit of all, of course, is to the environment, in the form of reduced emissions of greenhouse gases.

当然，由于减少了温室气体的排放而使环境受益最大。

Iron is a strong reducing agent for reducing the emissions of N2O in fluidized bed combustion of coal.

在燃煤流化床中少量的Fe可以高效地降低氮氧化物的排放。

In petroleum-coke-fired fluidized bed, Fe is a strong reducing agent for reducing the emission of NO.

在流化床燃石油焦过程中，Fe可有效降低NO的排放。

To find the mechanism of refluence in the flue,authors conduct the numerical simulation of liquid-field in the flue of multilayer building by adopting K-ε turbulent flow model and two-phase flow theory,and plots the charts that the pressure,consistency and velocity distribute in the flue.

为了探明多层住宅烟道串味的机理，采用κ-ε湍流模型，利用两相流理论，对多层住宅烟道内的流场进行数值模拟，得到烟道内的压强、速度和体积分数分布图。结果表明：在第一支烟道与主烟道的交汇处压强梯度较大，一楼排放的烟气大部分向上流动，第二支烟道附近油烟的体积分数梯度大

With the Carrousel Oxidation Ditch Process, which is commonly adopted domestically and internationally, the effluent would reach first-grade State discharge standard and be disposed into the sea while the mud would be sent to the Refuse Landfill Site after concentration and evaporation.

处理工艺上，采用目前国内外常见的卡罗塞尔氧化沟处理工艺，污水经二级处理后，水质达到国家一级排放标准，排入海中，污泥经浓缩脱水后送垃圾填埋场处置。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
