For transonic free stream, sudden performance degradation occurs. For the further supersonic range, performance losses increase slightly with increasing Mach number.
在继续的超声速范围内，性能损失随外流马赫数增加只有小幅增长。
It is shown that aerospike nozzle performance losses caused by free stream primarily result from increase of lift body base drag and decrease of plug pressure distribution.
结果表明，外流造成的性能损失主要体现在运载器底部阻力增加和塞锥表面压强降低两方面。
Second, markets have excessively rewarded short-term profits at the expense of lower long-term performance or plain losses.
第二，市场以降低长期利益或完全亏损为代价，给予短期逐利行为以优厚回报。
