大家注意！！
星尘可能不像我们在C片看到的那样！！
引一段Stardust论坛斑竹的话：
Please do, but be diligent. The images in the tutorial are not from the same aerogel samples that we are looking at. These were created elsewhere and used as approximations of what you might expect. Number 11 is much closer to what we've been looking at/seeing.
Consider the tutorial as more accurate description of how to look. We are looking for items that come into focus below the surface. Once you identify something, then you can analyse it more closely to see if it truly appears to be a 'track'. The tell-tale sign of shrinking ring fits the description of "looking down through a hollowed out carrot". Depending on the focus range of the FOV, you may even be able to spot a particle at the end of the carrot-shape.
就是说教程里边用的星尘样本跟真实的星尘可能不同~~~如果焦点过了表面以后发现有东西不是扩大而是收缩的话就可以报告了~~~不过要千万判断清楚~~~真正的Track拉到表面以下会缩小的~~~而且变得越发清晰~~~
附上一个超链接~~~里边有3个可以报告的目标~~~全部找到就很不错了~~~
