锗(Ge)是一种灰白色金属元素,具有质脆、单向导电等特性,用它制作的半导体元、器件,具有体积小、耗电少等优良性能。在收音机、电视机、计算机、雷达、火箭、导弹导航、电子通讯等电器设备中大显神通。锗还可作为燃料电池、热电偶、特殊合金的主要原料。人们利用锗的高折光率制成红外透镜,作为飞机红外远距离探测器、检查肿瘤的医疗器械等。近年来,锗在医疗保健领域中,利用锗能诱发人体内干扰素的产生,从而增强杀伤和吞噬癌细胞的能力,有利于肝癌、生殖系统癌症、白血病等恶性疾病的治疗和防治。锗在人体新陈代谢过程中的“氢离子”结合,能 Ge (Ge) is an off-white metallic element with brittle, one-way conductivity and other characteristics. The semiconductor elements and devices made from it have the advantages of small size and low power consumption. In radio, television, computer, radar, rockets, missile navigation, electronic communications and other electrical equipment in forensics. Germanium can also be used as a fuel cell, thermocouple, a special alloy of the main raw materials. People use the high refractive index of germanium made of infrared lens, as the aircraft infrared remote detectors, check the tumor of medical equipment. In recent years, germanium in the field of health care, the use of germanium can induce the body’s production of interferon, thereby enhancing the ability to kill and devour cancer cells, is conducive to the treatment and prevention of liver cancer, reproductive system cancer, leukemia and other malignant diseases. Germanium in human metabolism in the process of “hydrogen ion” binding, can
