Programs for Emission Cost Control Estimation System have been developed, which can predict the costs of emission, coal mix, desulphurization, discharge fee, emission allowance trade, and equivalent price with externality of electricity generation, and reduction of emission, and provide an optimized plan.

开发出SO2排放成本控制测算系统（SO2 Emissions cost Control Estimation System，以下简称ECCES）软件，可模拟实际情况，预测发电厂和发电集团公司的SO2排放成本、换煤成本、脱硫成本、排污缴费成本、排污交易成本、环保折价成本、减排成本和SO2成本控制最佳方案等。

Under conventional N fertilization and irrigation condition, N2O emissions during 2001-2002 and 2002-2003 in winter wheat and summer maize rotation system were 1959 g N hm-2 and 1250 g N hm'2, respectively; and 68%-86% of N2O emission occurred in summer maize growth season, the emissions mainly occurred in 2 weeks after N fertilization and irrigation. The highest flux rates were 5.06 mg m-2 d-1 and 5.60 mg m-2 d-1 in the rotation period of 2001-2002 and 2002-2003, which were happened at the ten-extended leaf stage in summer maize season when top-dressing N fertilizer was applied.

在冬小麦／夏玉米轮作体系农民传统的水肥管理处理中，2001-2002和2002-2003两个轮作周期内测得的N_2O的排放量分别为1959 gN hm~(-2)和1250 gN hm~(-2)，N_2O的排放主要集中在每次施肥和灌水之后的两周内，其中夏玉米十展叶期追肥后两周内N_2O的排放速率最高，2002年和2003年分别达到5.06 mg m~(-2)d~(-1)和5.60 mg m~(-2)d~(-1)。

Since put into production in May 2004, the unit performed well, actual sulfur-recovering efficiency is 90% above, moreover, the tail gas from unit meets the related environmental emission standard of nation.

装置于2004年5月初投产，生产运行情况良好，实际硫回收率在90%以上，装置排放尾气达到国家相关环保排放标准。

Bioethanol is produced from starch and cellulose components in biomass, which emit fewer greenhouse gases.

生物乙醇是从淀粉和纤维素成分的生物量，排放更少的温室气体的排放。

In a speech from the White House, the president did not offer a detailed formula to cut dangerous emissions, which scientists say trap heat from the sun leading to gradually rising temperatures on Earth.

在白宫的演讲中，总统并没有给出一个详细的方案来减少危险的排放，科学家们说温室气体的排放会阻挡太阳的热量从而渐渐升高地球的温度。

ACSA attempts to square this circle by setting up a sort of central bank of carbon, which would allow firms to borrow permits against their future allocations.

ACSA幻想设立某种形式的二氧化碳排放控制中央银行，允许公司以未来的配额为抵押来借用排放许可。

For the proposed project the waste gas emission locations include: preheating furnace of hard alloy parts line (when natural gas is used for heating while excess heat heating system goes wrong), melting furnace, refining furnace, heat treatment furnace for machining unit and steam boiler. The pollutants are SO2, NOx and smoke dust contained in the smoke generated from the above locations. All the above pollution generating facilities use the most clean energy, natural gas, for burning. Meanwhile, on melting furnace and refining furnace low nitrogen combustion technology such as low NOx burner is applied, and the generated smoke is discharged via chimney.

拟建项目之废气排放部位为硬质合金件生产线的预热炉（余热加热系统故障采用燃天然气加热时）、熔化炉和精炼炉及机加工机组热处理炉和蒸汽锅炉，污染物为以上部位产生的烟气中含有SO2、NOx以及烟尘，以上各产污设备均采用最清洁的能源——天然气为燃料，同时熔化炉和精炼炉采用低NOx烧嘴等低氮燃烧技术，产生的烟气由烟囱排放。

The PIXE results showed that chemical elements had different percentage in PM〓 coming from various sources. Factor analysis clarified Si、Ca、Al、 Fe、Mg and Ti in PM〓 came from earth surface or soils, S、Zn and Pb originated from industry emission, and Cl、As had a close relationship with combustion.

PIXE分析显示不同污染源产生的PM〓中的化学元素含量有着明显的差异，因子分析显示，PM〓中Si、Ca、Al、Fe、Mg和Ti来自地表土壤的排放；S、Zn、Pb代表人类活动的工业排放源；Cl、As与工业燃烧等人为活动有关。

Now the problem of global warming because of excess emissions of greenhouse gases. Excessive amount of carbon dioxide emissions, creating a diversified economy and La Nina phenomena lag disorder.
