因此需要实现高效化编程，将常用的程序标准化、共享化，减少新开发所需工时。工程类型，也就是上面所说的简单和结构化程序，如果我们所要控制的内容比较少，功能比较单一，逻辑不怎么复杂的可以选择简单工程，使用指令表、梯形图和SFC即可完成。如果是控制对象较多、大规模的过程控制或者分布式网络控制则需要采用结构化编程，通过再利用缩短编程时间、消减重新分配软元件的时间。简单化与结构化重要的区别就是“标签”的使用。

Communication cables are cables that transmit telephone, telegraph, facsimile documents, television and radio programmes, data and other electrical signals. Twisted by more than one pair of mutually insulated conductors. Compared with overhead open line, communication cable has the advantages of large communication capacity, high transmission stability, good confidentiality, less affected by natural conditions and external interference.

　　HYAC自承式电缆:适用于本地电信网的城市与乡镇电信线路，也适用于接入公用网的专用网线路。吊线和电缆用同一外护层，经济实用，安装敷设方便。HYA23铠装通信电缆机械保护层可以加在任何电缆上，以增加电缆的机械强度，提高防侵蚀能力，是为易受机械破坏和及易受侵蚀而设计的通信电缆。

对于密封式轴承，因内部已涂满润滑脂，不要用油煮加热，可用电加热法将轴承均匀加热后套入轴承上。我公司现全部采用电动轴承加热器进行加热)转子动平衡不好是产生机械噪声的主要原因，所以要提高转子的动平衡检验精度，尽量减少偏心的影响，保证电动机安装时联轴器的同心度。润滑油选用合适且无杂质。润滑脂的粘度大，噪声低。但粘度过大时，会有搅拌声。润滑脂充添量对于非密封式轴承，要在轴承内塞满润滑脂，润滑脂可由轴承的一端挤入，由轴承的另一端挤出，使润滑脂填充在轴承内，两端用手指抹平即可。
