理论分析与实验测试结果均表明,通过全局优化设计后,提高了轴流风机的效率,降低了噪音。
The results can provide the theory foundation for the optimistic design of the wall flow filter, and the qualitative and quantitative analysis of the particulate filter efficiency.研究结果可以为柴油机排气微粒壁流式陶瓷过滤体微粒捕集效率的定性与定量研究以及过滤体的结构优化设计提供依据。
I gravitated toward the field of clothing design, partly because it is a creative format that is modern and optimistic.我渐渐走入了时装设计领域,部分的原因就是它是一种现代而乐观的创造性事物。
