Probably never. But the Nest, designed by the minds behind the iPod, actually invokes that reaction — it predicts which temperature you'll want based on past behavior, and looks pretty sweet, too.
这个看似永远不会被发明出来，但是Nest做到了，它源自ipod的设计理念，能从你之前的行为预测温度，并且外形看起来很可爱，不是吗？
Many factors which may affect the catalytic behavior such as rare earth metal species, calcination temperature, reaction temperature, space speed and feed gas purity were studied.
并研究了不同稀土金属，不同焙烧温度，不同反应温度，不同空速条件及不同来源氢气等因素对催化性能的影响。
The behavior of different species during the temperature programmed surface reaction (TPSR) of methane over various catalysts is traced by an on line mass spectrometer.
利用在线质谱分析检测了在各种催化剂上甲烷的程序升温表面反应(TPSR)过程中不同物种的行为。
