“beta current gain factor(symbol: β)”的概念、定义、翻译、参考文献-科学参考

单词	beta current gain factor(symbol: β)
释义	beta current gain factor(symbol: β) Electronics and Electrical Engineering The short-circuit current-amplification factor in a bipolar transistor with common-emitter connection: $β = (\frac{\partial I_{C}}{\partial I_{B}}) V_{CE} constant$ where I_C is the collector current and I_B is the base current; the collector voltage, V_CE, is constant. β is always greater than unity and practical values up to 500 are used.
