Noninvasive Technique Gauges Art Canvas Health

非破坏性的技术检验艺术作品画布健康状况

Iconic works of art get exhibited worldwide. But as those paintings age, they can become too fragile to withstand travel around the globe. The paint can be visually examined to gauge its integrity. But the only way to check the canvas had been to remove a piece destructively.

So a team of researchers in Europe devised a new method for diagnosing the health of old paintings similar to testing blood sugar without using a needle.

因此，一个欧洲的研究团队发明了一种新方法，这种新方法可以检查古画的健康状况，类似于无针监测血糖GyNE^pNC(B+X。

The scientists took samples from nearly 200 old canvases or canvas linings from the 19th and 20th centuries. They shined infrared light on the fabric to assess the type of fibers and their relative fragility. With those results as a reference, the scientists then scanned 12 paintings by Salvador Dalí.

Luckily, all 12 are still in stable traveling condition. But they found that the oldest Dalís are starting to weaken. The research is in the journal Analytical Methods.

幸运的是，这十二幅作品还都适合旅行展出=lvY,Pv2++^&;G。但是他们发现达利最老的作品有些开始变差了!L[_j%PERg2。这项研究发表在《分析方法》杂志上

The scientists stress that the technique has only been validated for 19th- and 20th-century canvases with no synthetic fibers. But Dalí would have appreciated this marriage of science and art. After all, one of his works is called Homage to Crick and Watson.
