The algorithm needn't generate candidate itemsets and scan database, because it employs FP-Tree to store trasanctions in database compressedly and takes full advantage of the characteristic of FP-Tree.Consequently,the complexity of space and time the algorithm used is reduced obviously in the procedure of data mining.In a thorough experimental analysis of our algorithm on real and synthetic data,we isolate the effect of the individual components of the algorithm. Our performance numbers show that MFP-Miner outperforms previous work.

Jacobinism is not a supra-social 'revolutionary' category, but an historical product. It is the apogee of the tension of revolutionary energy in the period of self-emancipation of bourgeois society. It is the high point of radicalism that could be produced by bourgeois society, not through developing its own contradictions but by they stifled appeal to the rights of the abstract man and citizen; in practice, the guillotine.

雅各宾主义不是超越社会的&革命的&范畴，不是的，它是一个历史的产物，在资产阶级社会自我解放的紧张的历史时代里，雅各宾主义是规模精力高涨的顶峰，它是资产阶级社会－－不是在它的内在矛盾发展过程中，而是在它受排挤和压迫的过程中－－在理论上通过诉诸抽象的人和抽象的公民权利，在实践上通过断头台而能够达到的激进主义的极限。

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。
