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.

Methods Animals were randomly and equally divided into five groups: saline control group, positive drug control group, low-dose, medium-dose and high-dose crocetin group. Animals were anesthetized with urethane (1.2 g/kg), then followed by the perfusion of aconitine (10 μg/mL) through caudal vein in rats, or of ouabain (9 μg/mL) through external jugular vain in guinea pigs in a constant velocity of 0.1 mL/min, and the emergence time of ventricular fibrillation, ventricular extrasystole, ventricular tachycanlia and cardiac arrest were then detected and recorded. The recorded time was then translated to the cumulated amount of aconitine and ouabain. Experimental arrhythmia was induced by rapid injection of 4% CaCl2 (140 mg/kg), and the emergence time, persistence time, incidence and death of arrhythmia after the administration were observed.
