双语例句
- Without graceful degradation, Ajax-based mashup applications might find themselves missing out on both a minority user base as well as search engine visibility.
如果没有功能方面的让步，基于Ajax的mashup应用程序也可能会发现自己失去了部分用户群，搜索引擎的吸引力也会降低。 - First among them is its lack of provision for graceful degradation.
首先，它缺乏对功能退化的预防。 - The first one can be handled by what is know as progressive enhance or graceful degradation.
第一个级别的可访问性可以通过所谓的“逐步加强（progressiveenhance）”或着“优雅降级（gracedegradation）”来实现。 - Graceful degradation of data in extreme conditions;
在极端条件下可进行完美的数据退化； - An advantage of wavelet-based Video compression is that it offers more graceful image degradation at high compression ratios, and it also eliminates the block artifacts seen in DCT compression.
由小波变换编码实现的视频压缩在具备高压缩比的基础上，仍拥有较高的主观视觉效果，避免了由分块DCT变换引起的方块效应。 - With the goal of further reducing energy consumption based on energy-aware feedback scheduling, we analyze the dynamic behavior of control systems with variable sampling periods and suggest an enhanced energy-aware feedback scheduling scheme, which adopts the methodology of graceful performance degradation.
为了在能量感知反馈调度的基本框架下进一步降低系统能耗，我们通过考察控制系统在可变采样周期下的动态特性，基于适度退化的基本思想提出了一种增强型能量感知反馈调度方法。 - It is argued that integrated feedback scheduling could maximize resource utilization in underloaded scenarios, and could achieve graceful degradation of control performance under overload conditions. Consequently, the overall control performance could be significantly improved.
该方法在低载情况下可以最大化资源利用，在系统出现过载时可以获取性能的适度退化，因而能够明显改善整体控制性能。 - The measurement results demonstrate the desired graceful degradation as multiple devices fail, which indicates a good tolerance to device failures.
测试结果表明：当多个器件失效时，输出功率适度恶化，说明该功率合成放大器允许个别器件的失效。
