1945年的一天,美国贝尔电话研究所的专家们,在检查电话系统出现的障碍时发现蓄电池极板表面长出一些针状的晶体。这些晶体和极板虽属于同种金属,但强度大、弹形好。在显微镜下观察其形状,犹如动物的胡须,故取名为晶须,也称“须品”。 经过现代X光衍射技术显示,晶须内部的原子完全按照同样的方向和部位排列,构成了一种完全没有任何缺陷的理想晶体。因此能够具有很高的抗拉强度。目前,人们已
One day in 1945, the experts at the Bell Telephone Institute in the United States found some acicular crystals on the surface of the battery plate when checking the telephone system for obstacles. Although these crystals and plates belong to the same kind of metal, they are strong in strength and good in shape. Under the microscope to observe its shape, like an animal beard, so named whiskers, also known as “whiskers.” After modern X-ray diffraction technology shows that the whiskers within the atoms in exactly the same direction and location arranged to form a complete without any defects of the ideal crystal. So can have a high tensile strength. At present, people already
