电子被注入P区，而空穴被注入N区。 Electrons are injected into the P region, and holes into the N region. In the table, a notation(标记) of infinite impedance indicates that the terminating impedance should be a minimum of 10 to 100 times the nominal(额定) impedance at the specific port, and zero that it should be well less than a tenth the nominal impedance at the port and less than a hundredth if possible
