Question

帮我把英文翻译成中文，不要翻译器~~谢谢啊

In order to showthe effect of the jet outflowstream on the fluid movement, the velocity vector plot in an arbitrary horizontal slice going through the impeller for the single impeller setup is compared with that of the jet-impeller layout in Fig. 4. The equal
size vectors are used in the figure in order to show the fluid flow pattern. The angle of 45? between the jet and the impeller shown in this figure is just an example to show the role of the jet in the produced fluid flowpattern inside the tank. The figure shows that in the single impeller case, the fluid just moves forward from the impeller in a narrow region in front of the impeller. However,in the jet-impeller setup, the jet mixes the fluid in the middle of the tank more significantly and some internal loops produced in the fluid flow pattern improve the homogenization process.

Answer 1

翻译如下：
为了显示对喷射出来，流流效应对流体的运动，在一个任意水平切片速度向量图，通过对单叶轮安装叶轮中去，是相对于在图喷射叶轮布局。
4.平等
大小中使用向量图，以显示流体流动模式。在45角？之间的射流与此图中所示的叶轮只是一个例子来说明的Jet在水箱内产生的液体流型的作用。这个数字表明，在单叶轮的情况下，流体只是从前进中的叶轮前在狭窄的区域叶轮。然而，在喷射安装叶轮，射流混在油箱中更为显着，在流场的均匀化过程中产生的改善一些内部循环液。
有一些没空格……我替你补上了……有些失误
