摘要
黑孔的效果判定最快捷有效的一种方式是采用专用的测试片DTV（菊花链测试片）。利用黑孔的爬孔原理。通过哈氏槽试验后，检查DTV片的爬孔个数，判断黑孔的碳膜吸附是否良好。文章主要讲解DTV在黑孔工艺中的应用及影响DTV爬孔的因素。
The most effective way to evaluate the blackhole effect is to check the number of holes after passing through the Hull cell. Based on the blackhole principle, carbon membrane adsorption of black holes was determined by measuring the holes on DTV test paper. The application of DTV in black holes was discussed and the factors that affect the hole-climbing performance were analyzed in this paper.
