排放

On the base of indoor platform experiment in analogue tunnel pollution environment, and of testing the automobile coursing in practical road and practical tunnel environment, the paper decides the effect that road lengthways lope has on diesel smog emission.

在模拟隧道污染环境的室内台架实验和实际道路、实际隧道环境中车辆运行测试的基础上，确定了道路纵向坡度对柴油车烟雾排放的影响。

The droplet velocity and size distribution in the spray of diesel/dimethoxy methane blend was investigated using Phase Doppler Anemometry.

应用激光相位多普勒技术测量了含甲缩醛柴油喷雾的速度场和粒径场，在直喷式柴油机上研究了该含氧混合燃油的燃烧排放特性。

For the sake of differentiation exhaust limits anent the different use diesel engine.

为了解不同用途柴油机排放测试循环及限制的区别，在现有的台架上依照不同测试循环进行测试和计算分析。

The research result shows that the best fuel delivery advance angle of diesel engine used has been changed; with the first cylinder as the standard, the deviation of the fuel delivery advance angle between the first cylinder and other cylinder surpasses allowed range; the smoke emission and fuel consumption can be decreased and delivering fuel to each cylinder at the right time can be assured, through the selection and adaptation of fuel delivery advance angle .

研究结果表明：使用后柴油机的最佳供油提前角发生了变化；以第一缸为准，其它缸与第一缸之间的供油提前角偏差超出了允许的范围；实行供油提前角的调配可使各缸在正确的时刻供油，减少排放，降低油耗。

It has such functions as fuel injection controlling, air fuel ratio controlling full electronic ignition angle of advance controlling, idle stabilization controlling, fuel steam controlling, self diagnosis safety and it′s good in acce...

提高了发动机的输出功率以及整车的动力性和经济性，实现了对汽车发动机各种工况的实时控制，进一步降低了有害气体的排放。

If the advance angle of injection is adjusted too earlier, knock phenomenon will been show in the combustion process. EGR is a good way to improve NOx emission. If EGR is big, the ignition delay period will become long.

EGR率是改善NOx排放的有效手段，EGR率大的工况，滞燃期长，达到着火条件前，SMD在零附近的油滴更多，则汽化表面积越多。

In order to reduce the maximum combustion pressure and the NO, emission, it adopts smaller advance angle of fuel delivery. In most conditions, the combustion starts after TDC; the maximum rate of pressure rise, the combustion pressure and the heat release rate are lower; their relevant phases are retarded.

结果表明，为降低最大燃烧压力及NO、排放，小缸径直喷增压柴油机采用的喷油提前角较小，柴油机在大部分工况下，燃烧始点较迟，最大压力升高率、最大燃烧压力较低，其对应相位较迟，放热规律也较低。

This in pursuit of Copenhagen's aim to be the world's first carbon-neutral capital, by 2025. The staff are Anglophone, young, attractive and friendly.

这个是哥本哈根实现在2025年建成碳零排放的目标的一项措施之一，现场的工作人员都会说英语，他们很年轻，很吸引人，很友善。

The study will provide useful data on hygienic status of hospital sewage, both treated and untreated. We will also explore new methods of detecting water virus. Methods: Eleven hospitals were selected and sewage from those hospitals was investigated. Items chosen for analysis include the content of general chemicals, animalcule and virus, etc.

本研究通过对某市市区的11家医院处理的污水进行卫生学调查，检测医院污水中一般化学物、微生物、病毒的含量，了解排放的污水中各种污染物的分布情况，通过对不同类型的医院污水的检测，比较各种消毒处理'方法的消毒处理效果。

Kyoto, and the associated Marrakesh Accords, also established the CDM to provide a flexible mechanism for Annexure 1 parties and their businesses to meet their GHG reduction targets and to assist developing countries to achieve sustainable development.

东京议定书及其相关的马拉咯什议定书，还为已建立的清洁发展机制提供了一个灵活的机制，以使附件一及其企业能够达到减少温室气体排放的目标并帮助发展中国家完成可持续发展。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
