The daily maximum surface temperature appears on the coping of the sand dune, the minimum temperature and the greatest diurnal temperature range appear on the windward slop. 沙丘表面日最高温出现在顶部,日最低温和日较差最大值出现在迎风坡。
A maximum output power 4 W is obtained with slop efficiency 33.4% at 20 kHz. 在重复频率20kHz时,最大平均功率为4W(脉宽16ns),斜效率达33.4%。
