用几分钟的视频介绍一个有趣的知识
Huh? Film can also record sound?! Recording techniques you would never imagine!
你肯定知道，胶片可以记录电影画面。那电影的声音呢？实际上，声音也是记录在胶片上的，而它的录制和播放方式，巧妙得让你意想不到。那么，如何用胶片上记录声音？又如何将胶片里的声音播放出来？让我们回到有声电影的初期，来回答这个问题～
You must know that film can record movie images. What about the sound of a movie? In fact, the sound is also recorded on film, and the way it is recorded and played is so clever that you will never imagine it. So, how do people record sound on film? And how do they play the sound on film? Let's go back to the early days of sound films to answer this question.

动力的发展方向以电动化为主，这是因为电动化具有显著的环保优势，能有效减少碳排放和空气污染。随着电池技术的进步，电动设备的续航能力和充电速度大幅提升，使用成本也逐渐降低。此外，各国政府对电动化的政策支持和补贴力度不断加大，进一步推动了这一趋势的发展。电动化不仅适用于交通工具，也逐步扩展至工业和家庭用电设备，成为未来动力发展的主要方向。
