摘要
生物球晶属于溶致液晶,大量存在于动、植物体中,例如脑、神经、肌肉、血液、胆汁等与生命密切相关的主要组织中。对鸡胆汁、鱼胆汁、薰蚊草汁和樱桃汁用偏光显微镜拍照了140多张球晶照片,发现了生物球晶的双马尔特十字。从物理实质出发,根据球晶外部高分子有序晶层和内部高分子无序聚集态粘滞系数的不同,从物理上建立了“抛物线光轴”模型,由此揭示了双马尔特十字是球晶内部高分子无序聚集态在外部有序晶层的作用力下形成的。根据液晶易流动性质和抛物线光轴变化规律,对球晶施加微小外力,可能对诊断生命体患病前的信息比其他诊断方式灵敏可靠。
Spherical crystal in living organisms, which exists abundantly in the organisms of animals and plants such as brain, muscle, nerve, blood and bile etc, is one of lyotropic liquid crystals. Double Maltese cross of spherical crystal in living organisms is firstly found after chicken bile, fish bile, berry juice were observed by microscopes. After deeply investigated by optic methods, the forming mechanism of Double Maltese cross was found and a new concept of ＂parabolic principal axis＂ was proposed. Study indicates that Double Maltese cross is formed through the function of outer orderly crystal layers on the inner macromolecule. It may be more delicate and reliable to examine some serious diseases in their early stages according to the change of the parabolic principal axis of mildly forced spherical crystals.
