目前,在仪表行业中基本上使用着两种读出方式:数字式和模拟式。前者读数准确,响应快;后者可以反映出变化的趋势。二者各有千秋,因此两种读出形式现在还处于并存的局面。这里要谈的是一种既非数字读出又非模拟指示方式,而是所谓的“条状读 At present, basically two reading methods are used in the instrumentation industry: digital and analog. The former accurate reading, fast response; the latter can reflect the changing trend. Both have their advantages and disadvantages, so the two forms of readout are still in a coexistence situation. What we have to talk about here is a way of saying neither a number nor an analog, but the so-called "
