Scientific Testing

German physicist Wilhelm Conrad Röntgen (1845-1923) discovered a mysterious ray while experimenting with cathode ray tubes. This ray was invisible to the naked eye but could penetrate through many substances. Röntgen used this ray to take the first-ever X-ray image of his wife's hand. At that time, the nature of this ray was not clear, so it was named X-ray.

Through X-ray technology, we have the ability to "penetrate" the interior of the human body or objects without causing damage. In medicine, it can help doctors examine internal organs and bones. At airports, it can quickly check whether passengers' luggage contains prohibited items. In addition, X-rays can also reveal the internal structure and material information of artifacts, aiding in preservation and identification work.

From numerous X-ray images of artifacts, researchers discovered five different processing techniques at the junctions of the dolls' heads and bodies. Based on the analysis of these techniques, we can tell whether it is an original work by Ye Wang, a later repair, or an imitation.

What would these artifacts and common items in life look like under the X-ray machine at the airport? Let's take a look at their internal structures or skeletons!
