美国IBM公司的一些研究人员已发现了一种有机混合物。它在液态时不导电,但经紫外光线照射就转变成能导电的固体图象。虽然该项研究还处于初期阶段,但在文件复制和“电感图象”方面可能获得应用。用紫外线通过一影面或图样照射到该有机混合物上,然后冲洗掉没有被曝光的液体部份。用这种方法可获得任何期望的导电固 Some researchers at IBM in the United States have discovered an organic mixture. It does not conduct electricity in the liquid state, but is converted into a conductive, solid image upon exposure to UV light. Although the study is still in its infancy, it may find its application in document reproduction and “inductive images”. UV light is applied to the organic mixture through a photographic surface or pattern, and the unexposed portion of the liquid is then washed away. In this way any desired conductive solid can be obtained
