第八组 组员：张银、张磊、杨艳、 张国宇、曾艳飞、 * The properties of metalloids lie between those of metals 性能 准金属 位于 and those of nonmetals.This shouldnt surprise us since the metalloids are located between the metals and the nonmetals in the periodic table. 周期表 准金属的性能位于金属和非金属之间，我们不应该对此感到意外因为准金属在周期表中位于金属和非金属之间。 In most respects,metalloids behave as nonmetals, both 表现 chemically and physically.However,in their most important 化学 物理 physical property,electrical conductivity,they somewhat 物理性质 电导率 resemble metals. 在许多化学和物理方面，准金属表现为非金属的性质，然而，在它们很重要的物理性质电导率上它们又有点像金属。 Metalloids tend to be semiconductors-they conduct 趋向于 半导体 传导 electricity,but not nearly so well as metals.This property,particularly as found in silicon and germanium,is responsible for the remarkable progress made during the 可靠的 显著地 last decade in the field of solid-state electronics. 固态电子学理论 准金属趋向于形成能导电的半导体，但其导电能力不如金属。尤其是近十年期间在硅、锗元素中发现的这种性质在固态电子学领域里取得显著性进步是可靠的。 The newest hi-fi stereo systems,television receivers,and 主语 CB radios rely heavily on transistors made from 谓语 semiconductors.Perhaps the most amazing advance of all 发展 has been the fantastic reduction semiconductors have 缩简版 半导体 allowed in the size of electronic components. 以……的尺寸 电子元件 必威体育精装版的高保真立体音响，电视机卫星接收机和CB广播紧密依赖于半导体晶体管的制作。所有以认可半导体电子元件尺寸的微型版是令人最惊叹的发展 To it,we owe the development of small and versatile hand-held calculators and microcomputers.The heart of these devices is a microcircuit printed on a tiny silicon chip. 我们小型的、实用型的手持计算器和微型计算机都归功于微型半导体的发展。这些设备的核心是一个被印在微型电路上
