求翻译：目前，带式输送机的发展趋势是：大运输能力、大带宽、大倾角、增加单机长度和水平转弯，合理使用胶带张力，降低物料输送能耗，清理胶带的最佳方法等。我国已于1978年完成了钢绳芯带式输送机的定型设计。钢绳芯带式输送机的适用范围：是什么意思？

At present, the development trend of the belt conveyor is: a large transport capacity, large bandwidth, the inclination to increase the stand-alone length and level of turn, and the rational use of tape tension, the best way to reduce energy consumption, material handling, clean-up tape. China was c

Currently, belt conveyors are the trend of development of the capacity, the bandwidth, the pitch, and a stand-alone increased length and level with the Tape turns, reasonable tension, reduce energy consumption and material handling clean up tape the best way, and so on. My country has done in 1978,

At present, the belt conveyer trend of development is: Big transport capacity, the great band width, the great inclination angle, the increase single plane length and the flat turn, use the adhesive tape tensity reasonably, reduces the material transportation energy consumption, cleans up the adhesi

At present, the development trend of belt conveyors are: transport capability, bandwidth, the large turning angle, increase the single length and level, rational use of belt tension, reducing the energy consumption of material handling, the best way to clean tape. In China was completed in 1978, the
