弹性) solid body led, in the first instance, to the understanding of a concrete example of a medium which can transmit transverse vibrations(横向振动), and at a later stage to the definite conclusion that there is no luminiferous medium(发光介质) having the physical character assumed in the hypothesis.Р为了解释光学现象,人们曾试图假定有一种具有与弹性固体相同的物理性质的介质。这种尝试的结果,最初曾使人们了解到一种能传输横向振动的介质,后来确定不具有(存在)上述假定所认为的(那种)物理性质的发光介质。Р专业词汇(词根)简介Р1. 表示数量的词素Р1)haplo, mono, uni 单,一,独Рhaploid 单倍体;?monoxide 一氧化物;?monoatomic 单原子的;Р2)bi, di, dipl, twi, du 二,双,两,偶Рbicolor 双色;?dichromatic 双色的;?diplobacillus 双杆菌;?dikaryon 双核体; ?twin 孪生;?dual 双重的;Р3)tri 三,丙Рtriangle 三角;?triacylglycerol 三酰甘油;?tricarboxylic acid cycle 三羧酸循环;Р4)quadri, quadru, quart, tetr, tetra 四Рquadrilateral 四边的;?quadrivalent 四价的;?quadruped 四足动物;?tetrode 四极管;?tetracycline 四环素;
