The results shown that the oil-saving rates of fuel oil and lubricating oil are 5 % and 50% respectively by using GRT energy-saving oil additive, it have reached the level of same kinds of products in 80's from abroad; the cylinder wear of DONGFENG truck and JIEFANG was reduced by 24% and 33% respec-tively; the GRT additive improved obviously the seal property of engine cylinder, not only increasing the cylinder pressure nd the output power of engine to rise the acceleration and cold starting properties, but also improving the combustion situation of the fuel oil to decrease the environmental pollution from the exhaust of truck.

结果表明，应用GRT节能油添加剂可以分别节约燃料油5％以上和机油50％以上，达到了八十年代国外同类产品的先进水平；能使东风牌汽车和解放牌汽车的汽缸磨损分别降低24％和33％以上；使用GRT添加剂可以明显地改善发动机汽缸的密封性，不仅提高了汽缸压力和发动机的输出功率，使其具有良好的加速性和冷起动性，而且改善了燃料油的燃烧状况，从而减少了汽车尾气对环境的污染。

In this paper, the current status of the research and development of high temperature coal gas desulfurization sorbent in recent years were reviewed.Meanwhile the different methods of regeneration of spent sorbents and treatment of tail gas were dicussed in details.

Automobile exhaust emissions of pollutants containing 150-200 different compounds, the main harmful ingredients: no combustion or CH incomplete combustion, NOx, CO, CO2, SO2, H2S and the amount of aldehyde, phenol, peroxide , organic acid and lead, phosphorus formed by gasoline lead, phosphorus pollution.

汽车尾气排放的污染物中含有150～200种不同的化合物，其主要有害成分为：未燃烧或燃烧不完全的CH、NOx、CO、CO2、SO2、H2S以及微量的醛、酚、过氧化物、有机酸和含铅、磷汽油所形成的铅、磷污染等。

Using catalysts to purify automotive exhaust gas has more and more been regarded by human society. It is generally accepted that the most important factor in the catalyst is the oxygen storage materials, which have a direct relation to the puring performance.

采用催化净化技术来治理汽车排放污染正越来越受到人们的广泛关注，而其中储氧材料性能的优劣直接关系到汽车尾气净化催化剂的净化效果。

Regulations penalising vehicle emissions, and thus raising the cost of conventional cars, are tightening.

惩治车辆尾气排放的规章制度日趋严厉，传统动力车成本因此也将提高。

Nitric oxides emission from automobiles is one of the major air pollutants.

汽车尾气中的氮氧化物是主要的大气污染物之一。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
