干电池

At that time,according to input-output relation of operational amplifier,a dry battery was used to produce a fixed voltage to simulate the input signal and then make the oil mist detector work normally.

针对该故障当时的情况，利用运算放大器输入输出关系，采用由干电池产生一固定电压模拟输入信号的方法，使报警器恢复正常。

Currently, the power for sensor node is supplied by dry battery or fastener battery. So it is a challenging task to design energy-efficient data gathering protocols for wireless sensor networks.

由于目前的传感节点由干电池或纽扣电池来供电，因此设计能量有效的数据收集协议是无线传感网络研究中的一个挑战性课题。

The best one is supplied by accumulator. The flowmeter designed in this paper is true utra-low power consumption, and it can be supplied by dry battery.

本课题设计出的LS旋转流量计真正实现了超低功耗，可以采用干电池长期供电。

The flowmeter designed in the past couldnt decrease the consumption so low that the whole system can be supplied by dry battery.

以前的单表型流量计都无法降低功耗到足以用干电池供电，最多只是采用蓄电池供电。
