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 <em>smoke</em> <em>detector</em> 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 <em>smoke</em> <em>detector</em>s to be extremely sensitive, so that it will give a lot of false-positive alarms but no false-negative silence.
