固体的研究是目前在物理學中最有興趣之一。它不但在瞭解固体在物理学及化學過程中的机构上,有未經墾檜甚至未曾開闢的地域吸引物理學工作者去工作。而且在人類日益增長地利用佔据固體中重要地位的金属一方面。也有迫切的要求来认识固体,掌握固體性質的規律,從而可以更好地利用固體。可以想像得到的,固体的各种性質,如热学、電學、光學、力學等性质比了氣體的將要复杂得多,因此在目前我們對它的認識也沒有像我們對氣體的認識那麼多。 慶幸的是:自從X-射線晶體学發展以來,我們對於固體的認識從宏觀的、描寫的階段已進入了微觀的、開始能瞭解它的機構的地步。
Solid research is currently one of the most interesting physics. It not only learned about the solid bodies in physics and chemistry, but also unexplored areas of unexplored cypresses to attract physicists to work. And on the one hand, the growing use of mankind for metals that occupy an important place in solids. There is also an urgent need to recognize solids and master the laws of the properties of solids so that solids can be better utilized. It is conceivable that the various properties of solids, such as thermal, electrical, optical, mechanical and other properties are much more complex than the gas, so at this time we do not know it as much as we know of gas. Fortunately, since the development of x-ray crystallography, our understanding of solids has entered the micro-phase from the macroscopic, descriptive stage and began to understand its institutions.
