MWM engine makes the conversion among two-stroke mode, four-stroke mode and six-stroke mode of one engine come true in theory, filles in the blank with 1/3 which is the ratio of total strokes to working strokes in single working cycle of engine, possessing the continuous variable compression ratio of a certain range at the same time, combines the advantages of two-stroke engine and four-stroke engine, expandes the working range of engine greatly.

Secondly the estimation of power spectrum of flame signal was made, and it was found to be able to reflect the stability of combustion state, which meaned that when the results of estimation of power spectrum showed that the frequency range in which the signal had certain value of energy became wider, and the peak value became larger, the extent of combustion stability became worse.

本文首次将色度学的原理引入到煤粉火焰颜色定量研究中来，试验研究发现，火焰的色度坐标可以反映火焰中风煤配比的变化：当色度坐标变小时，对应于风煤比变大，并且色度坐标对贫燃火焰反应敏感。据此可用来监视燃烧火焰中风煤配比是否失调。

Its rule of change was obtained. On the basis of other studies, the flocculation kinetics and flocs structure was studied. By making some assumptions, collision frequency were presented. Then the the flocculation kinetics model was established through population balance equation. Comparison of experimental data and modeling results indicate that there are the same trend between the two. So the model can predict flocs number and size during flocculation of Yellow River's loess particles without using empirical parameters. The TEM and SEM were used to obsever flocs in the study of floc structure. The flocculation was divided as flocculi, floc and floc aggregate. The flocs structure model was established by assumption that particles position in floc accords with tetrahedron. The fractal dimension of model and experimental flocs was found to be coincident. So the model can reflect the structure of flocs formed in flocculation of Yellow River's loess particles by macromolecule flocculant at a certain extent.

最后，本文还对絮凝动力学和絮体结构进行了研究，在前人研究的基础上，针对高分子絮凝黄河泥沙，对絮凝过程作了一些符合试验条件的假设，建立了颗粒碰撞频率表达式，应用了颗粒数量平衡方程，从而建立了絮凝过程的动力学生长模型，模型计算结果与试验数据对比表明，二者趋势一致，在没有使用经验参数的情况下基本上能够描述黄河泥沙絮凝过程中絮体数量和尺寸分布的变化过程；对絮体结构的研究中，应用扫描电子显微镜和透射电子显微镜对絮体进行了观察，将絮体分为絮粒、絮团和絮网三个不同的生长阶段，通过假设颗粒结合位置符合正四面体，建立了絮体结构模型，计算得到的模型絮体分形维数基本与试验中的实际絮体相符，在一定程度上能眵反映高分子絮凝黄河泥沙生成的絮体结构。
