This product is suitable for electronic computers with rated voltage of 500V and cables with high re of anti-interference. Type K B low density polyethylene with anti-oxidation property is adopted for insulation of cable core. Polyethylene high insulation resistance, good resistance to voltage, small dielectric coefficient and temperature and the influence of variable frequency dielectric loss is small, can not only meet the res of transmission performance, and can ensure the service life of the cable. In order to reduce crosstalk and external interference between circuits, the cable adopts shielding structure. The shielding res of cables are respectively adopted according to different situations, such as the method of shielding the hinged combination, the method of shielding the hinged combination, and the method of shielding the hinged combination after the hinged combination. Shielding materials are round copper wire, copper belt, aluminum belt/plastic composite belt three. Shielding pair and shielding pair have good insulation performance. If there is potential difference between shielding pair and shielding pair, the signal transmission will not be affected.

θM为产生TM的角度。两相PM型或两相HB型的步距角一致。根据上式，以及《步进电机的基本特性：静态、动态、暂态转矩特性》一问中的式：θL=（2θM/π）arcsin（TL/TM）得知，负载转矩TL决定位移角θL的大小。由于步进电机的负载决定角位置，因此一定负载转矩TL时，θL越小，角度精度越高。因此希望步进电机大静态转矩（保持转矩）TM要大。连续测量TL与θL，就可以得到静态转矩特性曲线。步进电机的静态转矩特性，可以1相激磁，也可以2相激磁，A相与B相1相激磁转矩公式如下式所示，其中角度θ为电气角。

Armored communication cable structure: 1. Basic cable: any filled and unfilled cable with single sheath or double sheath structure. 2. Armored communication cable mechanical protection layer: type 53 adopts 0.15mm thick corrugated steel belt, which is longitudinal wrapped on the basic cable and overlapped on both sides. The surface of the steel belt is coated with plastic to prevent corrosion and water intrusion. The type 23,22 has similar performance with double steel band wrapping. 3. Armored communication cable sheath: black high-molecular weight low-density polyethylene or polyvinyl chloride thin sheath. Sheath thickness may depend on the basic cable outer diameter. 4, identification and marking: cable appearance with permanent identification mark, tag, at no more than alternate 1 m intervals between 5, sheathed communication cable tag contents are: the diameter of wire, wire on the , type of cable, length, factory name and year of manufacture. 6. Armored communication cable electrical characteristics: the cable meets all the electrical res of the basic cable. 7. Cable length: mechanically protected cable is manufactured according to the standard length of the corresponding basic cable

布线优化及丝印摆放“PCB设计没有、只有更好”，“PCB设计是一门缺陷的艺术”，这主要是因为PCB设计要实现硬件各方面的设计需求，而个别需求之间可能是冲突的、鱼与熊掌不可兼得。：某个PCB设计项目经过电路板设计师评估需要设计成6层板，但是产品硬件出于成本考虑、要求必须设计为4层板，那么只能牺牲掉信号屏蔽地层、从而导致相邻布线层之间的信号串扰增加、信号质量会降低。一般设计的经验是：优化布线的时间是初次布线的时间的两倍。

Power cables have many advantages and occupy less land. Generally, it is buried in soil or laid in indoor, ditch and tunnel. The insulation distance between lines is small. High reliability. It is less affected by climatic conditions and surrounding environment, stable transmission performance and high reliability. It has more favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature, superconducting power cable, etc. The distributed capacitance is large. Less maintenance. It's less likely to shock.
