The dynamic response of a simply supported circular plate under moderate impulsive loading is solved with the unified strength theory.

采用统一强度理论求解了简支圆板在中等脉冲荷载作用下的动力响应问题,得出了统一的动力塑性极限荷载、内力场和速度场,并给出了上限解和下限解。

Medium PRF and N/M detection rule is the general working model of airborne pulse Doppler radar, it is necessary to satisfy the demand that medium pulse repetition frequency(PRF) set can solve ambiguities of range and Doppler, besides the demand, the blind zones of range and Doppler occurred by the medium PRF set should be minimum.

机载脉冲多普勒雷达常采用中等脉冲重复频率,N/M检测准则工作方式,在该方式下对重复频率的要求主要是能解距离及速度模糊,且能使距离与速度遮蔽区域尽量小。
