The degradation kinetic model of head rice yield was developed using Artificial NeuralNetwork (ANN). 用人工神經網絡研究了稻穀出米率的退化動力學模型。
Hitting a dust mote-sized particle would impart the same kinetic energy as slamming head on into a speeding freight train. 與塵埃級別的顆粒相撞，都可能得到與高速貨車迎麪相撞的能量。
Two types of tidal energy can be extracted: Kinetic energy of currents due the tides and potential energy from the difference in height (or head) between high and low tides. 兩種類型的潮汐能可提?。弘娏?，由於潮汐的動能和勢能之間的高度，從在漲潮和退潮（或主琯）的差異。
