这段话应该如何翻译？求助大神指点！！！！！感激不尽！！！ In this study we compared the performance of a new MB die technology to that of the conventional slot MB die technology.The new parallel plate MB die is simple in design with a cost only one-tenth of the conventional MB die. Experimental results showed that this new die configuration with in-house modification could be used to fabricate meltblown fibrous media in the range of 3–10 mm by modulating the process conditions. However, conventional slot MB die produced fibers that were three to five time smaller than what can be produced using the parallel plate MB die design at similar process conditions. The meltblown media produced with the CS MB die achieved 1.5–3 times smaller pore size and showed 1.5-2 times higher filtration efficiency. These results taken together indicate further modification needs to be implemented to the parallel plate MB die to bring it in line with its CS analog. We discussed some design modifications that could potentially enhance the parallel plate MB die performance such as decreasing the internal die resistance to air flow to increase air velocity, increasing the number of air nozzles around the polymer nozzles, recessing the polymer spinnerets above the die face, and having inclined air channels to increase the drag force and fiber attenuation. |

在这项研究中，我们比较了新MB挤压技术与传统的狭缝型挤压技术的性能。新型双板式MB挤压设计简单，成本仅是传统MB挤压式的十分之一。实验结果表明，通过调节加工条件，内部改性的新型挤压式构造能被用来制造熔垂纤维介质。但是，在相似的加工条件下，传统的狭缝式MB挤压生产出的纤维比前者要小三到五倍。用CSMB挤压法生产的熔吹介质孔径可减小1.5至3倍的孔径，过滤效果提高1.5至2倍。以上结果表明，双板式MB挤压要做进一步修改才能与CS类似 太专业了  搞不定 |
