It was found that indene and naphthalene, which have harmful effects on the combustion property, were produced because of the hydrogen transfer reaction at high temperatures. High conversion ratio and low content of aromatics could not be obtained simultaneously.

在较高温度时，由于氢转移反应，产物中出现了茚、萘等低氢碳比化合物，会影响燃料的燃烧性能，应用时需要根据性能要求在高裂解转化率与低芳烃收率之间进行权衡。

ABSTRACT Development of internal combustion engine has been directed by energy saving and environment protection for a long time. Because lean burn technique has great potential to improve fuel consumption and emissions, it has been paid much attention. Variable induction and twice injection [patent no. 98107693. 9] , which have been developed in recent years, have also shown good effect on engine performance.

能源与环境现已成为内燃机技术发展的主导因素，稀薄燃烧由于其能够很好地改善发动机燃油经济性和排放特性而受到广泛重视；可变进气、二次喷油[专利号：98107693.9]等近年来发展起来的技术也表现出良好地改善发动机性能的能力。

Based on the former works by our group, the variable induction devices including swirl and tumble variable devices were developed and the variable induction and twice injection were combined to optimize the lean burn combustion and improve fuel consumption and emissions in this thesis.

本文在课题组前面研究工作的基础上，设计了可变涡流与可变滚流两种滑动式可变进气结构，并将可变进气与二次喷油结合起来优化稀薄燃烧过程，改进发动机经济性与排放性能。

Nitrogen is inert and will not support combustion; however, it is not life support ing.

氮是不活泼的，不支持燃烧；但是它不是维持生命的必要元素。

Nitrogen is inert and will not support combustion; however, it is not life supporting .

氮是不活泼的，不支持燃烧；但是它不是维持生命的必要元素。

Experimental results show that the equivalence ratio f has a significant effect on the intensity of thermoacoustic instability. In order to sustain the combustion in the Rijke combustor, the inferior and superior limit of the equivalent ratio was 0.63 and 1.75 separately.

试验发现，化学当量比f 对Rijke预混燃烧器内热声不稳定的强度有重要的影响，维持Rijke预混燃烧器持续燃烧的下限极限化学当量比和上限极限化学当量比分别为0.63和1.75。

The process of combustion of inflammable materials producing heat and light and smoke.

易燃物燃烧发出热、光、烟的过程。

The effects of initial state of reactant mixture on combustion kinetics were studied.

本文研究了反应物起始条件对SHS过程燃烧动力学的影响。
