尊敬的雷老师，经过多日实验，我发现了我称为质速积（mv）的物理量的守恒，我将其记为p。实验装置如下图所示，两个滑块进行相对运动最终碰撞，用光电门记下碰撞前和碰撞后的两滑速度。最终发现，两滑块mv之和前后不变。其中v为矢量。这可以认为是k=1时的运动力守恒，即一般情况下的运动力守恒。@最爱春雷2021

也许是椛口上

有一种是加上一些特殊词语会显得诡异：如错误，无法，已失效\删除，未找到，不存在等，最典型的案例就是您拨打的电话是空号，还有那个“经多方核实，该地名不存在”的都市传说
还有一种是语句重复或出现大量乱码：
您好！鬘鬘【锟斤拷锟斤拷?,*该站点已经*un锟斤不存在鬘鬘鬘鬘拷锟斤拷&],停止运行，。请$鬘鬘鬘鬘鬘】】联系管理员了解详情！
顺带一提b站的错误视频也挺吓人的
