将模拟结果代入相关的费用计算模型，并利用探试成本函数概念，估算不同切割位置分离序列的年总成本。

The simulation results were substituted in the cost models and annual total costs of separation sequences were estimated, taking account of heuristic cost function.

他们操作的遥控装置可以改变截煤机的方向、位置和速度，这台德国产的截煤机可以沿着一道300米宽的煤面来回进行切割。

They work with remote control devices that change the direction, position and speed of a German-made cutting machine that slices back and forth along a 300-metre-wide coal face.

在设计的时候在要记得，计划好钻孔的位置，如何从铝板料，聚乙烯或谷类食品盒上切割零件，还要平衡重量。

Remember to plan where the screws go, how you will cut your parts out of sheets of aluminum, HDPE, or cereal boxes, and to balance the weight.
