The results indicated that following the increase of acetanilide loading, PVC crystalline was raised first and then decreased, when acetanilide content was 3%, PVC crystalline reached the maximum and the tensile strength was the strongest; the micro morphology was changed from an even cloud-like structure to an fiber like network, and the perfection of the network was raised first and then lowered, as made the elongation at rupture rise first and then decline.

结果表明：随着乙酰苯胺质量分数的增加，PVC结晶度先增后降，当乙酰苯胺质量分数为3%时，PVC结晶度最大，拉伸强度也最大；微观结构逐渐由均匀的云片状结构变成网络结构，且网络的完善性先增后降，使得材料的韧性先增后降。

Results indicated that the content of polyaniline had significant influence on the anticorrosive performance of the coatings.

结果表明：聚苯胺含量对涂层的防腐蚀性能有较大影响，当涂层中聚苯胺含量较低时，随着聚苯胺在涂层中质量分数的增加，涂层的防腐蚀性能相应提高；随涂层中聚苯胺质量分数的进一步增大，涂层的防腐蚀效果开始下降；涂层中聚苯胺含量为5.0%时具有最佳的防腐蚀性能。

The effects of blackening time and the mass fraction of phosphorus of the coating on the morphology of a porous coating was investigated.

As the first attempt, this paper applies the laminar flamelet model to the typical diffusion combustion in diesel engines. A database of the laminar flamelet for a DI engine is built up in the phase space of the mixture fraction with the scalar dissipation rate as parameter.

以KIVA-3程序为基础，摒弃其原有的化学反应模型，模拟内燃机缸内多维湍流流场，并补充求解混合分数的时均值及其脉动均方值的湍流输运方程，得出各曲轴转角下混合分数的时均值及其脉动均方值的缸内空间分布。

The results showed that the degree of butyryl substitution of CAB increased and the degree of acetyl substitution of CAB decreased as the activation time increased. The degree of substitution of CAB changed slightly after the esterification went along about 2h.

随着活化时间的增加，CAB的丁酯取代度会逐渐增大，乙酯取代度会逐渐减小；酯化反应2h后，CAB取代度变化不大；CAB的丁酯取代度随着反应体系中丁酰基摩尔分数的增加而增大，而乙酯取代度则随着丁酰基摩尔分数的增加而减小。
