Then the FLUENT software was used to simulate the amphibious vehicle' ambient flow field through defining the unsteady boundary condition. The lift, resistance, velocity, pressure, and wave of the amphibious vehicle moving in the regular waves were obtained, which can avoid the errors resulted from neglecting the free surface and provides theoretic basis for the research on optimization design of high performance amphibious vehicle.

在计算出某改进型两栖车在微幅规则波中高速迎浪运动时升沉和纵摇特性的基础上,运用FLUENT软件,通过自定义非定常入口边界实现了两栖车在微幅规则波中运动的三维流场数值模拟,得到了升力、阻力、速度、压强和兴波等流场参数,实现了两栖车在波浪中的绕流场数值模拟,解决了以往由于忽略兴波特性导致数值计算结果随航速提高误差不断增大的问题,为高性能两栖车的外形设计研究提供了理论依据。

The main peaks of the EEG power spectra were in delta and theta frequency range. In the stage of ethanol exposure, the rats exhibited much more act of attack than the control, the alpha waves of EEG decreased, while the delta waves increased. The EEG power spectra analysis showed the delta power increased and the theta power decreased. In the stage of ethanol withdrawal, the rats showed some withdrawal behaviors such as wet dog shakes, sniffing, groomingand tonic-clonic seizures for audiogenic stimulus. Spikes and spike-slow waves were found in the EEG. In power spectra analysis, the delta power decreased while the alpha and the theta power increased, the EEG frequency band moved to the high-frequency rang. These changes were found obviously on the sixth day and disappeared on the 1 Oth day after the ethanol was removed.
