A pilot scheme on the use of clean lpg and electricity by public light buses has been launched . after completion of the scheme early next year , we will decide on measures for its long - term implementation 公共小巴试用电力和石油气等低污染燃料的计划已经展开，明年年初完成试验后，我们会决定长远推行的方法。
This paper explores the dynamics of the economic growth rate in the presence of an explicit link between the agricultural biotechnology and environmental protection in an endogenous growth model 摘要本文探讨农业生物科技研发出低污染的农耕技术对农业生产、环境品质所产生的正面影响，提升农业永续经营的可能性。
The design of gasketed joints is critical for low - emission applications . for better control and elimination of unwinding of spiral wound gaskets , a fully - enclosed gasket cavity is desirable 对于低污染排放应用来说，垫圈连接设计是关键性的。为了更好的控制和防止螺旋式垫圈的退绕作用，需要配置完全包装的垫圈腔。
The modeling strategy is that the government per - announce policy that imposes a lump - sum tax and the technology to the biotechnology development low pollution agriculture is being subsidized 本文以内生成长模型为理论架构，探讨对生物科技开发的低污染农耕技术给于补贴，提高它与现有的农耕技术竞争能力，并且使用定额税融通补贴。
As the growing scale of the high - level architecture and city engineering in recent years , a underground structure with strength , stiffness , stability and low noise is most needed 近年来，随着我高层建筑和市政工程建设规模的日益扩大，需要一种既能满足一定的强度、刚度和稳定性要求；又能满足低噪音，低污染要求的地下结构形式。
Among their solutions is the engine fuelled with alternative fuels , which has advantages of both high thermal efficiency and low exhaust emissions and will be most competitive in the next decades 代用燃料在内燃机上的应用成为解决这两个问题的有效途径之一。 lpg柴油双燃料发动机以其高效率，低污染将成为最有前景的发动机之一。
A new package of measures was announced in may 2000 to improve air quality by providing incentives to hasten the introduction of cleaner vehicles and fuel and to significantly reduce harmful emissions by diesel vehicles 政府亦公布一系列改善空气质素的新措施，鼓励加快引入低污染的车辆和汽油，以期大大减少柴油车辆所排出的废气。
Developing the technology of power electronic integration is a quite important tendency in new century in order to improve the high power density , efficiency and reliability of system , meanwhile , to decrease the cost and pollution 大力开发电力电子系统集成技术实现系统的高功率密度、高效率、高可靠性、低成本、低污染的性能是新世纪电力电子技术发展的趋势。
