single stage extraction的意思|示意

Compared with the traditional reactor, the single stage extraction distribution ratio increasing by about 20% in the impinging stream reactor under the same conditions.

在相同条件下，与传统反应器相比，撞击流反应器单级萃取分配比可提高约20%。

Both the extraction ratios of countercurrent multi-stage extraction and cross current multi-stage extraction were higher than single-stage extraction.

多级逆流或错流萃取的萃取率明显高于单级萃取。

Under these conditions, the extraction yield of single - stage extraction is 56% and that of four - stage extraction is over 98 %.

在最佳工艺条件下单级萃取率为56%左右，四级萃取率可达98%以上。
