单端放大器的输出级由一只放大元件(或多只元件并联成一组完成对信号正负两个半周的放大，单端放大机器只能采取甲类工作状态

热丝具有电阳随温度变化的特性，当有一恒定直流电通过热导池时，热丝被加热。由于载气的热传导作用使热丝的一部分热量被载气带走部分传给池体。当热丝产生的热量与散失热量达到平衡时，热丝温度就稳定在一定数值。此时，热丝阻值也稳定在一定数值。

The output stage of a single-ended amplifier is composed of an amplifying element (or multiple elements connected in parallel to form a group) to amplify the signal for plus or minus two and a half cycles, and the single-ended amplifying machine can only adopt Class A working state.

The hot wire has the characteristic that the anode changes with temperature. When a constant direct current passes through the thermal conductivity cell, the hot wire is heated. Due to the heat conduction of the carrier gas, part of the heat of the hot wire is carried away by the carrier gas and part of it is transferred to the tank body. When the heat generated by the hot wire is in balance with the heat lost, the temperature of the hot wire is stable at a certain value. At this time, the resistance of the hot wire is also stable at a certain value.
