历时多年的胆石之争,现已告一段落。晶体管以其体积小、重量轻、耗电小、价格低廉、无需预热等先天优势,广泛地活跃在军工、民用、仪器、家用电器、电脑等领域。而电子管从诞生至今,已逾百年之久,虽然在晶体管无孔不入 After many years of gallstone struggle, now come to an end. Transistor with its small size, light weight, low power consumption, low cost, without the inherent advantages of preheating, widely active in the military, civilian, equipment, household appliances, computers and other fields. The tube since its inception, more than a century, although the transistor pervasive
