内容原创请勿盗版
(Verse 1: Experiment Background & Purpose) 第一部分:实验背景和目的
Long long ago, the atom's structure, a mystery untold, 很久之前原子的结构是一个谜
Scientists curious, the world they want to behold. 科学家对他们不知道的世界很好奇
Rutherford and his team, an experiment designed, 卢瑟福和他的团队设计了一个实验
Alpha particle scattering, the atom's secrets to find. 阿尔法粒子散射,找到了原子的秘密
(Verse 2: Experiment Setup & Materials) 第二部分:实验设计和材料
Gold foil so thin, atoms aligned in a row, 金箔如此薄,原子排行
Pressed to few layers, background scattering low. 压成几层原子厚,减少背景散射
High atomic number, positive charge defined, 原子数高,(原子核的)正电荷高
Stable and reliable, gold is the perfect kind. 稳定和可靠,金是最佳选择
Alpha source strong, heavy with positive might, 阿尔法射线源头,粒子重而且带正电荷
With nucleus collide, scattering comes to light. 当和原子核碰撞,散射会发出“光”
Particles same speed, lower KE, more deflection, 粒子都是相同的速度出射,如果动量小,则有更大的偏转
Vacuum is crucial, no air, no absorption. 真空是必须的,没有空气,没有空气吸收
Fluorescent screen glows, tracking where particles fly, 荧光屏发光,用来检测粒子往哪里飞
Experiment all set, ready for the try. 实验准备好了,准备开始尝试
(Verse 3: Experiment Results) 实验和结果
Most alpha particles, pass straight through with no bend, 大部分阿尔法粒子直接穿过没有偏转
Some are deflected, at small angles they tend. 少数偏转,角度很少
Very few bounce back, greater than ninety degrees, 非常少的撞回去,角度大于90度
A surprising result, putting minds at unease! 一个让人惊讶的结果,让人内心不平静
(Verse 4: Experiment Conclusion) 第四部分:实验结果
Nucleus is tiny, compared to the atom's space, 原子核很小,和原子的空间比起来
Nucleus is charged, positive in its place. 原子核带电荷,在它的位置带正电荷
Most of the atom's mass, in the nucleus resides, 大部分原子的质量集中在原子核呆着的地方
A tiny center holds, where great power hides. 一个小小的地方储存着巨大的能量
