空壳体
[病毒] empty capsid
- 首先，一枚空火箭壳体撞入卡比欧斯陨石坑。
First, an empty rocket hull slammed into the Cabeus crater. - 灌溉水经壳体上节流孔和空腔体，流速被降低，再经过丝网板和渗水物质的阻尼作用，水流量被有效抑制。
Water flows through the orifices on the casing into the empty cavity to reduce its flow speed, and then through wire screen and permeable substance to control the flow. - 随着流量的增大，水声信号在参考频域能量的峰值先增大后减小，其对空化的敏感性大大强于壳体振动信号。
the reference frequency band energy peak value of sound pressure first rose then dropped along with the increase of flow rate, and its cavitation sensitivity is stronger than the vibration signal.
