电子计算器和大部分家电一样已进入寻常百姓家。电子计算器品种繁多,按功能分有四则运算和函数两大类,还有多功能的如带时间显示和定闹功能、太阳能。按显示器分有萤光和液显示,前者读数清淅,但耗电多达几十毫安,为早期产品,后者读数需光线明亮,但耗电极少仅几十微安。有太阳能电池的几乎可以不用换电池,使用较为方便。不管那一类计算器,都可以分为显示器、连接导线、按键、集成块、电池及其他元
Like most appliances, electronic calculators have entered the homes of ordinary people. A wide range of electronic calculators, according to the function of the four operations and functions are divided into two categories, there are multi-functional, such as time display and set downtown function, solar energy. According to the display is divided into fluorescent and liquid display, the former reading Qing 淅, but the power consumption up to tens of milliamps, as early products, the latter need to be bright light readings, but less than the power consumption of only a few dozen microamps. There is almost no need to change the battery with solar cells, the use of more convenient. No matter what kind of calculator, can be divided into monitors, connecting wires, buttons, manifolds, batteries and other elements
