The power consumption of battery-driven micro-machined gas sensors is more critical. 摘要由电池驱动以微机械技术制造的气体传感器的功耗是十分关键的实际问题。
Although some other gas sensor array systems have been tested at the prototype stage, few have been used in real time measurement situations. 尽管一些其他气体传感器阵列系统在原型阶段经过了测试，但在实时测量情况下却很少被使用。
