Question

求高手帮忙翻译一下。急急急。非常感谢。

This test is quite simple and involves conducting computations of hood performance by changing the number of openings at the hood inlet. Fig. 2 shows iso-values of species concentration for various numbers of slots for a constant outlet mass flow rate of 0.1 kg/s. Although this qualitative view indicates better suction with the increase in the number of openings, a quantitative analysis is required. This result is illustrated in Fig. 3, where the total mass of the contaminant in the entire room has been plotted against the number of slots. Based on this simple representation, it appears that the optimum outcome corresponds to 6 slots, and that a further increase in their number does not help to reduce the species concentration. On the contrary, it amplifies it.
a) open
b) two slots
c) four slots
d) six slots

Answer 1

这个测试非常简单,主要是通过改变机罩进风口的数量评估机罩的性能.图2显示维持0.1kg/s恒定出风流量的不同槽数的烟气浓度值.尽管这个质性观点说明,开口数量越多,吸力越好,但是还需要进行量性分析.结果如图3所示,整个房间内的污染物总质量已经根据槽的数目划出.根据这个简单的表述,似乎最佳结果是6个槽.槽数再往上增加并不会降低烟气浓度,反而会使其增加.

希望能帮到你!如果你介绍一下这是什么产品,可能更好翻译一些.

Answer 2

这次考试很简单,包括进行计算,通过改变罩性能的数量在引擎盖开口进口。图二显示iso-values物种集中的各种数字槽固定出口质量流率0.1公斤/秒。尽管这一定性观点表明吸与更好的增加开口,定量分析是必要的。这个结果了图3,在那里的总质量的污染物在整个房间已被人谋害隙的数量。在此基础上简单的表达,看来最优结果符合6槽,进一步增强了他们的号码不有助于降低物种浓度。相反,它会加剧。
一个开放
b)二槽
c)四槽
d)六槽
