中文摘要： 传统微燃烧所用燃料普遍为气体燃料，不能实现液体（油、醇类）、固体（煤、金属）、生物质颗粒（稻草、秸秆）及混合燃料等的燃烧，而且单颗粒和颗粒群燃料的燃烧及气化机理至今仍不够明晰。因此，本项目提出一种新的微燃烧和气化操控方法和技术：利用单光镊对单微颗粒燃料进行悬浮定位，通过高能激光点燃，对微燃烧和气化过程进行光学式测试，进一步揭示单颗粒燃料微燃烧和气化机理；利用阵列光镊对两颗颗粒燃料进行测试，可获得颗粒间相互作用机理，对颗粒群燃料进行时、空定位，按照既定方式组织燃烧和气化并测试，达到有效操控的目的。本项目采用全光学式颗粒悬浮定位、点燃以及测试方法，对颗粒微燃烧和气化进行无干扰式测试，最能反映微燃烧和气化真实性，还原其本质，有效揭示其机理，可作为标准性燃烧和气化测试方法，克服现有微燃烧和气化机理研究的难题。该技术不仅能应用于能源领域，而且可用于环境化学、生命科学、生物医药和航空航天等诸多领域。

英文摘要： Gas fuel is widely used in classical micro-combustion system, but liquid fuel (oil & alcohols), solid fuel (coal & metal), biomass fuel (straw & stalk) and fuel combination et al still have not been used till now. Combustion and gasification mechanism of single fuel particle and fuel particle group still hasn't been disclosed by a complete insight. This project proposes a novel controlling method and technique for micro-combustion and gasification. First, single fuel particle is levitated and positioned using single optical tweezers, and is ignited by laser with high power. Micro-combustion and gasification mechanism of single fuel particle can be disclosed as further by testing and analyzing the combustion and gasifying process parameters. Second, two fuel particles can be trapped and tested by array optical tweezers, interacting mechanism can be obtained. Moreover, particles group fuel can be trapped and positioned in space-time by array optical tweezers, and combustion and gasification of them are executed and tested by established mode for effective control purpose. Research of this project can reflect the truth, restore the nature and disclose the mechanism of micro-combustion and gasification by non-intrusive optical testing technique. Thus, research technique of this project can solve the difficult of mec
