安装烟雾探测器可以帮助防止火灾。

Installing smoke detectors can help prevent fire.

通过与Honeywell公司的合作，NASA发明了第一款可调节式烟雾探测器，这种探测器能够调节探测的敏感程度，从而防止发生误报警。

Teaming up with Honeywell Corporation, NASA invented the first adjustable smoke detector with different sensitivity levels to prevent false alarms.

因此，工程师们故意设置烟雾探测器偏于敏感，这会有很多假阳性警报，但肯定没有假阴性错误。

So the engineers deliberately make smoke detectors to be extremely sensitive, so that it will give a lot of false-positive alarms but no false-negative silence.
