The results indicate that the difference between the top and the bottom kerfs width of the die-board along eight directions is not sensitive to linear polarization with altering laser power and cutting speed, while the kerf width difference of steel is on the contrary.

试验结果表明，改变激光功率和切割速度对模切板进行切割，上、下切缝沿不同方向之间的宽度相差不大，即偏振性对高吸收率非金属材料模切板的切缝影响不大，但是对金属材料影响很大。

Using the CO2 laser with 2000W,it can gets high cutting quality of carbon steel which thickness less than 10mm with kerfs width: 0.2mm and the heat-effected zone:0.15-0.3mm.

2000W的CO2激光可对厚度10毫米以下的碳钢进行优质切割，切缝宽度为0.2毫米，热影响区为0.15~0.3毫米，可对4毫米厚度以下的不锈钢进行优质切割。

Highly absorptive nonmetallic material, die-board, was cut by linear polarized CO2 lasers through eight different directions. Effect of laser power, cutting speed and assisted air on the width of the cut kerfs of the die-board was also discussed by contrast with that of lower carbon steel.

为了研究线偏振CO2激光对高吸收率非金属材料的影响，采用线偏振CO2激光沿着不同的方向切割模切板，研究不同激光功率、切割速度、切割方向、辅助气体对切缝宽度的影响，同时对比线偏振激光切割低碳钢。

Since the method causes serious depletion of ore during mining of upper plate,the inclined cutting raise heading together with inclined medium or deep hole kerve is suggested.

以无底柱为代表的崩落采矿法中，切割拉槽至关重要，而目前无底柱采矿大多采用垂直切割天井与切割平巷并配以中深孔联合拉槽的切割方法，但该方法在对矿体上盘回采过程中损失贫化较大。
