可编程序电子计算器可以像电子计算机那样编制程序,进行程序运算。它具有语言简单,便于掌握;价格便宜,适于普及:体积小、可随身携带;维护简单,便于管理的特点。在进行电气计算时,由于涉及到的原始数据较多,常常要查阅手册,样本。这对于保证计算的正确性,提高计算的速度、效率都是很不利的。例如变压器的型号不同,规格不同,相应的△P_d、U_d%、P_O、I_O%均不相同;电缆的截面规格不同,相应的电阻、电抗以及载流量等等都不同。能否把这些数据放在小
Programmable electronic calculator can be programmed like a computer, program operation. It has a simple language, easy to grasp; cheap, suitable for universal: small, portable; easy to maintain, easy to manage features. In the electrical calculation, due to the raw data involved more often have to refer to manuals, samples. This is to ensure the correctness of calculation, improve the calculation speed, efficiency is very bad. For example, different types of transformers, different specifications, the corresponding △ P_d, U_d%, P_O, I_O% are not the same; cable cross-sectional specifications, the corresponding resistance, reactance and carrying capacity and so on are different. Can these data be kept small?
