查询词典 at the expense of...

Numerical results show that with O-QoS constraints, the lightpaths can be established efficiently at the expense of a little resource reusability or blocking probability.

网络设计实例与仿真结果表明了在较好的传输条件下线性损伤对网络性能的影响可以忽略不计，当传输层特性降低到一定程度之后网络的性能急剧恶化。

To have a little fun at the expense of the worst troublemakers, the referees working the game would sometimes make a modest friendly wager amongst themselves: first ref to give one of the bad boys a technical foul wouldn't have to tip the ball boy that night.

对付那些最糟糕的闹事球员，裁判们会在一场比赛中找点乐子，比如有时他们会在这些球员身上下一个比较低调友好的赌博：第一个给这些坏小子们一个技术犯规的裁判可以不给球童小费。

Simulation results show that our algorithm enforces the adaptability of differential space-frequency modulation to the time delay expansion.Finally, we give our work to reduce the complexity of multiple symbol differential sphere decoding in differential space-time modulation. Through the modification of the enumeration strategy of the search tree in sphere decoding, we significantly reduce the complexity of detection at the expense of little loss on performance.

理论分析和仿真结果都验证了这种检测算法对长信道时延的适应能力论文最后还对差分空时调制中的多符号检测算法进行了研究，提出了一种降低差分空时调制系统中多符号差分球形译码算法复杂度的方法，通过改进球形译码中搜索树的排序策略，使得系统在牺牲较少性能的基础上大大降低了算法实现的复杂度。

He saved the girl at the expense of his life.

But in other areas such as state protection for small retailers, distorting fuel and fertiliser subsidies, and labour laws that protect the organised minority at the expense of the vast majority the government needs to step back.

但在其它领域--比如对小型零售商的国家保护、扭曲市场的燃料和化肥补贴，以及以绝大多数人为代价而保护少数有组织工人的劳工法律--政府需要退居二线。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
