俄罗斯国家光学研究所和军事医学研究院的专家最近开发出了用液晶检测肿瘤性质的新方法，可对早期肿瘤进行较准确的诊断。液晶是介于液体与晶体之间的一种物质，其各个方向上的分子排列取向和运动规律均不一样。将液晶置于不同物体表面，其呈现出的物理性质就会根据物体表面的
Experts from Russia’s National Institute of Optics and Military Medical Research Institute have recently developed new methods for detecting the nature of tumors using liquid crystals, allowing more accurate diagnosis of early tumors. Liquid crystal is a substance between the liquid and the crystal. The alignment and movement of molecules in each direction are different. The liquid crystal is placed on the surface of different objects. The physical properties it presents will be based on the surface of the object.
