Results indicate that TiC-VC particles can be produced by direct metallurgical reaction between ferrotitanium, ferrovanadium and graphite during the laser cladding process.

研究结果表明，通过钛铁、钒铁与石墨之间的反应，可以得到TiC-VC复合碳化物增强相，细小的TiC-VC复合碳化物颗粒弥散分布在Fe基体之中，合金熔覆层的耐磨性在一定范围内随增强颗粒的增加而提高。

It have sufficient space to wash fiber balls in filter to increase efficiency of backwash .

逆洗的方式需先以逆向进水将滤层抬起，然后再以气、水联合冲洗，重覆约4~5次后可完成逆洗过程，耗水量只有0.12%，过滤器内部的高度则建议以纤维球的自然高度的二分之三倍为佳，使纤维球在过滤器内有足够的空间漂洗，增加逆洗的效果。

The collecting efficiency and the pressure drop of the moving granular bed filter can be predicted conveniently.

在此基础上，考虑全床内粉尘沉积量的不均匀分布，建立二维的移动颗粒层除尘过程模型。

Furnace Door made by the plate, a jigsaw puzzle inside a lightweight firebrick insulation tiles in the Furnace Door open a central observation of theworkpiece heating holes, in order to prevent heat from Lost in the hole, fill the hole with a layer of transparent film Mica, the open and close of Furnace Door are completed by the handle.

炉门由钢板制成，里面砌有保温砖有轻质耐火砖，在炉门中央开有一个观察工件加热情况的小孔，为了防止热量从孔中逸散，在孔内填有一层透明的云母片，炉门的启闭是由手柄机构来完成的。

The ceramic layer does not crack or flake off when heated to 800℃ and then quenched.

将陶瓷内衬复合钢管加热至800℃高温，然后水淬，陶瓷层不炸不裂。

Compared with the graphite, the coefficients of friction of the RL-C/C are lower under the same load of about 0.08-0.12, and the increasing range of the volume losses are still lower than those of the graphite. Compared with the SL pyrocarbon material, the COF and the volume loss of the SL-C/C are about 0.02-0.05 and 0.2 mm^3, lower than those under the same load. The COFs of most RL-C/C and SL-C/C specimens remain stable or decrease slightly with time, while those of the graphite and pyrocarbon specimens increase. The thickness of the integrated friction film of the RL-C/C decreases with load, but the wear surface of the SL-C/C is rough. Tough the wear surface of the graphite is integrated, the serious abrasive wear make the debris move easily and accumulate on the edge of the wear trace to form a restacked morphology. On the wear surface of the pyrocarbon material, some loosed debris, circular worn holes and flake worn out pyrocarbon has been found.
