1、method of file compression this app uses is many times referred to as the “Black Hole” by developers because of its extremely high compression ratios and mega-fast decompression.───这个程序使用的压缩算法通常被开发者们称作“黑洞”，这是因为它有着极高的压缩率和超快的解压速度。
2、As the gas approaches the black hole, the compression makes it glow hotter and brighter.───气体靠近黑洞时，由于受到引力的挤压，温度越来越高，同时发出愈发明亮的辉光。
3、Factors such as exports are tend to be stable, while domestic demand and capacity compression are unstable factors which are likely to be the black swan fly over the market.───出口等因素趋于稳定，而内需与产能压缩才是不稳定因素，是可能飞过市场的黑天鹅。
