光学望远镜在数角秒内就能获取一张星空图—至少比肉眼能获取的大60倍。

Visible light telescopes can resolve a piece of sky just a few arc seconds across — at least 60 times a smaller patch of sky than can be resolved with the human eye.

从图4可以看出，对于几乎每一个负载水平，调优后的ondemand调控器(利用率阈值为98)比默认ondemand调控器的能效都略高一些。

Here you can see that for almost every load, the tuned ondemand governor with an upwards utilization threshold of 98 is slightly more power efficient than the default ondemand governor.

实验结果表明，该方法大大提高了编码速度，而且能获得高压缩比和满意的恢复图象质量。

Experimental results show that the coding speed is much enhanced while high compression ratio and well-reconstructed image can be obtained.
