“装修隐蔽工程很重要”，几乎所有装修过的人都听说过这句话。但是对于大多数人来说，这九个字不够是一句口号而已，并未落实到实践中去——少数人选择落实，但也不过是把装修预算向隐蔽工程稍微倾斜而已。但是很明显，仅仅这样做还是不够。低质量的建材、低水平的工艺，依然能在用户的眼皮子底下顺利交工。究其根本，是用户没有利用好验收这道门槛——我们今天要说的，就是装修电路改造的验收。电路改造验收应该分两次进行——第一次验收第一次电路验收，时间在水电改造刚刚结束，墙地面施工工人入场之前。

Crane or forklift should be used for the loading and unloading of cables. It is forbidden to run flat or lay flat. For installation of large cables, cable laying cart should be used to avoid external damage or abrasion caused by manual dragging. If the cable cannot be laid in time for some reason, it should be stored in a dry place to prevent sunlight from exploding and water entering the end of the cable. Note: the installation of wire and cable should be familiar with the performance of wire and cable installation personnel or full-time technical personnel, if there are still unclear matters, ball related technical department or technical department of our factory.

另外建议数据线必须与高压线隔离。6．超过500Kbit/s的数据传输速率时应避免使用短截线段，应使用市场上现有的插头可使数据输入和输出电缆直接与插头连接，而且总线插头可在任何时候接通或断开而并不中断其它站的数据通信。
VR型步进电机定子磁极吸引转子时，由于转子磁极为**磁极，有磁化的N极和S极，不论定子绕组激磁所产生极性为N极还是S极均会产生吸引力。定子磁极激磁为N极时，吸引S极性转子磁极，激磁S极性的定子磁极会吸引转子的N磁极。定子磁极需要极性的切换。激磁定子磁极的线圈为单线圈绕组，磁极正反切换，则电流需正反向流因此驱动电路为双极方式。磁极上绕有两个线圈组成双线圈，一个线圈直流通电产生的极性，与另一个线圈直流通电产生的极性相反，此为单极方式。
