每个灯能被精确控制为研究者和高精度相机提供稳定、聚焦的光线。
Each lamp can be precisely controlled to provide even, focused light for the researchers and high-definition cameras.
第二种可能性则能应用在更加耗电的设备上。其原理是发射一道精确聚焦的红外激光线，击中光伏电池，由此能够将光束转换回电能。
A second possibility, for more power-hungry devices, is to fire a finely focused infrared laser beam at a photovoltaic cell, which converts the beam back to electrical energy.
研究者们还应该聚焦于精确地理解为何完美主义根据不同的情境会和好的或坏的健康状况联系在一起。
Researchers should also focus on understanding exactly why perfectionism is associated with poorer health or better health, depending on the situation.
