某单自由度系统受如图所示的矩形脉冲力<img src="https://static.zxtiku.com/wangke/imgs/topic/9a9f101dd94f7e02641dadc094393879.png"/>的作用，这里<img src="https://static.zxtiku.com/wangke/imgs/topic/b079576cf940c7b2ecf8e5aece657925.png"/>为单位阶跃函数。假设初始位于静止状态，忽略阻尼。系统的响应可以写为<br/> <img src="https://static.zxtiku.com/wangke/imgs/topic/9969089bd030f37cb7045b1a04910494.png"/><br/> 记在<img src="https://static.zxtiku.com/wangke/imgs/topic/16a9b119b5e351dd2a63244825c9d257.png"/>时刻达到最大位移<img src="https://static.zxtiku.com/wangke/imgs/topic/09fdd1cc7f5821536595cd5bc08dd34d.png"/>，静位移记为<img src="https://static.zxtiku.com/wangke/imgs/topic/36e2ed13971bf1f11c9ff0170a6d75ba.png"/>，<img src="https://static.zxtiku.com/wangke/imgs/topic/9249cd57c6807ac3944eba61d7fc58f8.png"/>为系统自由振动的周期，放大系数<img src="https://static.zxtiku.com/wangke/imgs/topic/3cebaca3572bdd0f758394aea2bdc908.png"/>，则<img src="https://static.zxtiku.com/wangke/imgs/topic/f978d429e4db7f24be3f8584656f78a0.png"/>的取值是与矩形脉冲作用的时间<img src="https://static.zxtiku.com/wangke/imgs/topic/620448a9f0e2761ba6f366beac0400fa.png"/>有关的，下列哪项是错误的？<br/> <img src="https://static.zxtiku.com/wangke/imgs/topic/00129110fd2152d12d70d7181d0f2535.png"/
