line spacing
2.The companies manufacture various professional electronic links, Jiechajian procedures, audio, video plugs line, computer peripheral plugs line, AC, DC plugs lines, the various emission line spacing and Jiechajian procedures applicable to different types of home appliances, communication products and equipment control circuits connecting.
3.In order to solve the problems which exist in belt forming machinecontrol technology Based on several kinds of electronic devices-digitalsignal processor (DSP), inverter, magnetic-powder lutch application, several primary control sections of forming machine are researched firstly, including cotton ropes constant tension control, main axis speed control and platoon line spacing control, and control principle, method and realization of each control section are analyzed.
6.The maximum attended section is 126km Nominal unattenced repeoter spacing is 1.5km Maximum-1.55km, Each terminalerpeater section may be composed of 7 attended section, corresponding appreximately 840kmSpacing of pre-equalization section is one half of attended sectionand each regulator section contains 6 basic line repeaters corressponding 9 km.
