金屬氧化物在常溫下是絕緣體， 制成半導(dǎo)體后卻顯示氣敏特性， 其機(jī)理是比較復(fù)雜的。 但是，這種氣敏元件接觸氣體時(shí)，由于表面吸附氣體，致使它的電阻率發(fā)生明顯的變化卻 是肯定的。這種對(duì)氣體的吸附可分為物理吸附和化學(xué)吸附。在常溫下主要是物理吸附，是 氣體與氣敏材料表面上分子的吸附，它們之間沒(méi)有電子交換，不形成化學(xué)鍵。若氣敏電阻 溫度升高，化學(xué)吸附增加，在某一溫度時(shí)達(dá)到大值。化學(xué)吸附是氣體與氣敏材料表面建 立離子吸附，它們之間有電子的交換，存在化學(xué)鍵力。若氣敏電阻的溫度再升高，由于解 吸作用，兩種吸附同時(shí)減小。例如，用氧化錫（SnO2）制成的氣敏電阻，在常溫下吸附某 種氣體后，其電阻率變化不大，表明此時(shí)是物理吸附。若保持這種氣體濃度不變，該元件 的電導(dǎo)率隨元件本身溫度的升高而增加，尤其在 100~300℃范圍內(nèi)電導(dǎo)率變化很大，表明 此溫度范圍內(nèi)化學(xué)吸附作用大.

相對(duì)來(lái)講，DSP控制的電源采用數(shù)字濾波方式，較MCU控制的電源更能滿足復(fù)雜的電源需求、實(shí)時(shí)反應(yīng)速度更快、電源穩(wěn)壓性能更好。
