Since the 2008 launch of the high-speed rail network between Rome and Milan, trains have become the preferred means of travel across Italy for locals and tourists alike.
自2008年罗马和米兰之间的高铁网络开通以来，火车已成为本地人和游客在意大利各地出行的首选交通方式。
Ferrovie dello Stato Italiane, the publicly controlled group that owns train operator Trenitalia and the national train network RFI, said 23 percent of all high-speed trains it operated were late in 2023.
意大利国家铁路集团是一家国有控股集团，旗下拥有列车运营商意大利铁路公司和国家铁路网络公司RFI。该集团表示，2023年其运营的所有高速列车中有23%晚点。
A mixed system means that high-speed trains must travel on the regular tracks on certain routes or when passing through large cities.
混合系统意味着高速列车在某些线路上或经过大城市时必须在普通轨道上行驶。
If there’s congestion or, for example, a local train breaks down, the entire high-speed network is affected.
如果出现拥堵，或者比如某列普通列车发生故障，整个高铁网络都会受到影响。
One of the most important changes the upgrades will bring is the segregation of the high-speed line from the regular one in certain urban centres through the construction of underground rail links.
升级改造将带来的最重要变化之一，是通过修建地下铁路连接线，在某些城市中心将高铁线路与普通线路分开。
It will allow for a reduction of the distance between high-speed trains travelling on the same line at any given time, which should mean a significant increase in capacity and traffic fluidity, according to Giuricin.
据朱里钦说，这将缩短任一时刻同一线路上行驶的高速列车之间的距离，这应当意味着运力和交通流畅度的显著提升。

Peters’ signature shot is a butterfly “take-off”, showing the multiple wing-beats of one butterfly in one frame as it lifts off from a flower. How does he capture it? Technology helps. A typical digital SLR camera shoots 20 frames a second. He uses a high-speed OM System which shoots 120 frames a second.
彼得斯的招牌镜头是蝴蝶“起飞”，在一帧画面中展现一只蝴蝶从花朵上起飞时的多次振翅。他是如何拍到的？技术帮了忙。一台普通的数码单反相机每秒拍摄20帧，而他使用的是每秒可拍120帧的高速OM System相机。
That makes it sound easy, and artificial, but Peters insists it is still a massive challenge. He typically takes between 10,000 and 20,000 shots to get one butterfly take-off sequence in focus. At such high shutter speeds, the depth of field is tiny, and as butterflies do not fly in a straight line they swiftly flutter out of focus. As well as thousands of attempts, it takes patience and fieldcraft to anticipate a butterfly’s likely flight-line — and catch it — in focus.
这听起来既简单又人为，但彼得斯坚称这仍是一项巨大的挑战。他通常要拍一万到两万张照片，才能得到一组对焦清晰的蝴蝶起飞序列。在如此高的快门速度下，景深非常小，而且蝴蝶并不沿直线飞行，很快就会扑腾着飞出焦点。除了成千上万次的尝试，还需要耐心和野外经验来预判蝴蝶可能的飞行路线——并在焦点内捕捉到它。

The growth in public money for academic research has speeded the process: federal research grants rose fourfold between 1960 and 1990, but faculty teaching hours fell by half as research took its toll.
用于学术研究的公共资金的增长加速了这一进程：1960年至1990年间，联邦研究经费增长了三倍，而由于研究占用了大量精力，教师的授课时间却减少了一半。
