power nap <有效午睡>
A power nap, also known as a Stage 2 nap, is a short slumber of 20 minutes or less which terminates before the occurrence of deep slow-wave sleep (SWS), intended to quickly revitalize the napper.
有效午睡，也叫浅度睡眠，指睡眠时间在20分钟以内的午睡，在进入深度睡眠之前就会停止，可以使睡眠者快速恢复精力。
理想的午睡时间是20-25分钟。睡得时间长了，容易进入深睡眠或快眼动睡眠阶段。
这个阶段人体的肌张力是降低的，心跳呼吸不均匀，如果进入这些阶段并从此阶段醒来的话，很多时候会感觉全身无力、心慌不适，有的人甚至郁郁寡欢、无精打采。

【Nitrification and Denitrification Processes in Rice (Oryza Sativa), with an Emphasis on Reduced Water Irrigation Regimes in USA】
#论文##水稻##灌溉#
Rice research is increasingly focused on the nitrification-denitrification process because of emerging irrigation regimes that reduce water applications. This review focuses on recent research involving nitrification and denitrification, with an emphasis on rice. The review also focuses on the emerging irrigation strategies associated with furrow irrigation and alternating wetting-drying irrigation.
