Through a nozzle atomizer, water is sprayed into the evaporation chamber of low-temperature and low-humidity air environment to exchange heat and make evaporative cooling. Eventually, it reaches a predetermined subcooling temperature, releases the subcooling state after the cold-releasing equipment, and then becomes crystals. 蒸发过冷室是该制冰系统的关键部件,水通过喷嘴雾化进入蒸发室的低温低湿空气环境中进行换热与蒸发降温,最终达到预定的过冷温度,经过冷解除装置解除过冷成为冰晶。
However, in the classroom, when the Q& A behavior completed successfully between teachers and students along a predetermined orbit, teaching activities are usually in the coordination state. 然而,在课堂教学中,当师生之间的问答行为如果能够按照教师预定的轨道顺利完成,教学活动通常会处于协调状态。
