1. A new type of alloy chute surfacing electrode was designed to repair the chute abraded and to obtain a high wear-resistance alloy layer on the low carbide steel surface of the chute. 研究了一种新型合金溜槽堆焊焊条，用堆焊的方法修复已经磨损的溜槽以及在低碳钢槽体表面堆焊耐磨层，制造出新型高耐磨性的合金槽体。
2. By the way of rational design including: chute, chute inclination, line and precise calculation reaches to the high operation of transport equipment and coal storage. 通过对溜槽的断面、倾角及线路的合理设计，并经过精密计算，实现了运输设备和存煤装置的高效运转。
3. Replace chute is simple, we can use tool for replace chut to change the chute. 溜槽更换的方法比较简单，采用的是溜槽更换装置加有上部的电动吊车或起重葫芦配合，人工更换。
4. After contrast and analyse, it was found that wall-hung spiral chute is ascendant and oecumenical than wall-laid spiral chute. 通过对比得出了壁挂式相对嵌入式螺旋溜槽的优越性及技术经济效果。
5. The fluctuation archives of vitreous sliding door child go up, each have two parallel chute, go up archives chute is a bit some deeper, it is commonly 8, 10 millimeter. 玻璃拉门的上下档子上，各有两条平行的滑槽，上档滑槽稍深些，一般为8—10毫米。
