研究结果表明：(1)补燃室头部距离的增加能增强补燃室头部回流以及提高燃料在补燃室后段分布的均匀性，但也减少了燃料与空气在补燃室后段进行掺混和燃烧的长度：(2)在一定范围内，增加一次燃气喷嘴面积能提高冲压发动机燃料的燃烧效率：(3)进气道夹角对冲压发动机中燃料的燃烧影响复杂，对于采用对称结构喷嘴的冲压发动机，当进气道夹角等于180°时，燃料与空气的掺混效果最好；而对于一次燃气喷嘴采用不同偏心结构的冲压发动机，补燃室内流场与燃料燃烧效率随进气道夹角变化的规律基本相似。

树枝状-线形嵌段共聚物是另外一类包含树枝状聚合物结构单元的聚合物类型，这种复合结构结合了嵌段和树枝状聚合物的优点，表现出独特的熔融和溶液性质，在理论研究和实际应用方面都具有重要的研究价值。

Among these results, we suggested that the monomer structure play a important role between E-O performances and morphology. Monomer STD02 shows fastest response time, and monomer M3 exhibits slowest one. As a result for roughness, it's the same with response time. From SEM photograph, the beadlike morphology was obtained from monomers without spacers. On the other hand, the filberlike morphology was obtained from monomers with spacers. It's suggested that the more harder structure will lead to the former, and the more softer structure will lead to the latter.

发现 STD02 反应时间最快，而 M3 则是最慢，而粗糙度大小也是与反应时间相符合，最大的是 STD02 而最小的是 M3，在 SEM 下结果显示，各单体所呈现的型态皆为颗粒状且排列均匀，因无含烷链段关系导致形成的型态为颗粒状，论文里有提到另一种单体含烷链段其所形成的型态为纤维状，以结构上来看，越是刚硬之单体所形成的型态都较易为水滴或是米粒状，而结构上越是柔软，所形成的型态都较易为稻穗或是纤维状。
