The results from electron micrographic analysis show that soot oxidation is influenced by aggregation and agglomeration of soot particulates, at the same time, the crystallograms show that the previous soot particle is non-crystal carbon, but in the latter conbustion period, a very small amount of crystal soot with unstable lattice at relatively higher flame temperature is formed. The crystallization happens greatly in period of combustion when temperature is relatively lower. The smoke particulates consist of crystal carbon similar to chaoite crystal latice and noncrystal carbon.

碳粒浓度和KL变化曲线表明预混合火焰中碳粒浓度远远小于扩散火焰，其原因在于不均匀的燃油—空气混合气结构在高温缺氧条件下产生大量碳粒，在温度峰值附近碳粒浓度亦达到峰值，其后迅速氧化，当温度低于2000°K时碳粒基本上不氧化，碳粒的电子显微分析表明碳粒的氧化受碳粒的集聚过程的影响，在燃烧初期碳粒是非晶体，碳粒的结晶在燃烧后期和排放过程中大量出现，排放碳烟微粒由晶体和非晶体碳组成。

And the conditions in cell suspension culture of Mikania micrantha were studied. The results showed that sucrose was the compatible carbon sucrose, and 30g/L sucrose concentration can satisfy the growth of Mikania micrantha cell; ammonium was absorbed under different sucrose concentration that haven't demonstrated significant specificity, and was completely absorbed on the lag phase and the early logarithmic phase; while nitrate was mainly absorbed on logarithmic phase. The density-dependent of Mikania micrantha cell starting to grow and density-inhibited of cell growth were proposed, the fittest inoculating quantity of Mikania micrantha in cell suspension culture was 40g/L.

并对微甘菊细胞悬浮培养条件进行研究，结果表明，微甘菊细胞生长适宜的碳源是蔗糖，并且较合适的蔗糖浓度为30g／L；在不同蔗糖浓度下氨基氮的吸收差别不大，氨基氮在迟滞期和对数期前期已基本消耗完毕，对数期生长主要利用硝基氮，因而提出，在微甘菊细胞液体悬浮培养中，氮源可以采用初始低氨基氮浓度，对数期中间维持高硝基氮，而且对数期中逐步流加少量的氨基氮；微甘菊细胞迟滞期分裂启动存在密度依赖现象，对数期生长存在密度抑制现象，最适接种量为40g／L。
