Particle Object To Instance 要实例化的粒子对象
Some scientists have taken to underground searches in hopes of catching just a few out of the multitude of dark matter particles in a rare instance of actually bouncing off of a regular particle.
一些科学家寄希望于地下的搜索,当大量的暗物质粒子通过时,在极少数的情况下,会有一些微粒被正常的粒子弹开,通过捕捉正常粒子的波动就可以抓住微量暗物质的踪迹。
And that's the following. Let's take a particle that is moving in the x-y plane, so that at one instance-- sorry, let me change this graph-- is here--oh, this is bad.
接下来,我们来看一个物体,在 x-y 平面内运动,在这个例子中,对不起,我要重画一下这个图,在这里,这画得不好
