In the identical working tempt the difference between tempt on the surface and the working tempt is even greater and that reduces the working life of the heating filament.
同样工作温度，丝表面温度与工作温度相差更大，从而降低电热丝的寿命。
The heater is composed of a housing, a heating filament arranged in the housing, and a switch, a transformer and a power plug sequentially connected with the heating filament.
加热器由外壳，设于外壳内的加热丝，以及与加热丝依次连接的开关、变压器、电源插头构成。
Semiconductor devices have no filament or heaters and therefore require no heating power or warm-up time.
半导体器件没有灯丝，因此也不需加热功率或加热时间。
