The difference between these two scenarios may have implications for how these supernovae can be used as "standard candles" — objects of a known brightness — to track vast cosmic distances.
这两种图景之间的差异可能会与超新星被当成“标准烛光”(也就是亮度已知的天体)来测量遥远宇宙距离的方式有关。
In our standard video test (running an MPEG4 video clip on loop, WiFi on, screen at roughly 65 percent brightness), the iPad 2 managed an astonishing 10 hours and 26 minutes of non-stop playback.
在标准的视频测试中(循环播放MPEG4视频，打开WiFi，屏幕亮度设为65%)，iPad2得到了10小时26分的好成绩。

In scene matching, false matching occurs due to brightness, contrast, scale, noise, and rotation difference between real-time target image and standard target image.
景象匹配中，实时目标图与基准目标图之间的亮度、对比度、噪声水平以及旋转等差异是造成误匹配的重要原因。
