板金工

Second, capacity: I plant and the existing common for 120 sets of equipment, major equipment 20 / 5 tons of Taiwan lane 1, 10 tons lane three, automatic welding machine 1 Taiwan ( Welding diameter Φ4000 mm), automatic 2-Bending Machine (Coil thickness to 30 mm), plasma cutting machine 4, welding machines and various kinds of exchanges welder more than 20 Taiwan, the large arm drill three (hole diameter Φ80 mm ) And metalworking cutting equipment over 40 Taiwan, Bending, presses, baking equipment.

我厂现有各种专用和通用设备120台套，其中主要设备20/5吨行车1台、10吨行车3台，自动电焊机1台（焊接直径Φ4000mm），自动卷板机2台（能卷板厚度30mm），等离子切割机4台，氩弧焊机及各类交流焊机20多台，大型横臂钻3台（钻孔直径Φ80mm）及金工切削设备40多台，弯管机、压力机、烘烤设备等。

This method is most special is the principle of simple and clear, setting out the process visible and tangible, it is applicable to a little bit knowledge of sheet l scene lofting geometry, which is a revolutionary approach, which not only greatly reduced the mapping workload, but also a great convenience in construction. Same time, it can also be a more traditional method (open show diagram drawing or galvanized sheet cut oil felt like, after re-opening in the pipe body gestures draw the cutting line method) is more accurate and pipe sections match exactly between the butt, thereby ensuring the steel fork tube and bend production quality.

该方法的最大特就点是原理简单明了，放样过程看得见摸得着，很适用于稍有一点几何常识的钣金工现场放样，这是一革命性的方法，它不仅大大地减少了制图工作量，而且也极大方便快捷了施工，同时它还可较传统方法（绘制开口展图后用油毛毡或镀锌板裁样再后在管身上比划绘出开口切割线的方法）来得准确无误与管段间对接严丝合缝，进而保证钢岔管和弯头的制作质量。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
