一、化学运动是物质固有的一种属性世界上的物质种类繁多,据统计,光地球上的化合物就有近二百万种,动植物也有一百多万种,宇宙间还有无数的天体,在这些星体上可能有各种各样的化合物,乃至独特的生命存在方式。如1969年9月在澳大利亚落下的一颗陨石中,发现有18种氨基酸;宇宙航行员从月球上带回的岩石样本中也分析出数种氨基酸。甚至曾被认为是虚无缥缈的星际空间里,也发现二十多种星际化合物,如 CN、CH、OH、NH_3、H_2O、HCN、CH_3OH、H_2N—CHO 等。上述种种形式的物质是由什么东西构成的呢?从化学观点看,它们都是由各种元素构成的。目前人们已知道的化学元素已有106种,从外层空间获得的现有科学资料表明,在别的星体上存在的化学元素也还是这些种类,只不过数量各不相同而已。例如,在太阳上已发现有69种元素。那么,是否可以说世界统一于化学元素呢?不行。因为元素由原子构成,原子又是由一些更基本的粒子构成,这一来,是不是世界统一于基本粒子呢?也不。因为物质是无限可分的,基本粒子并不“基本”,它还可以
First, the chemical movement is an inherent property of the material properties of a wide variety of substances in the world, according to statistics, there are nearly two million kinds of compounds on Earth, there are more than one million species of plants and animals, the universe there are numerous objects , There may be a wide variety of compounds on these stars, and even a unique way of life. As one meteorite dropped in Australia in September 1969, 18 amino acids were found; astronauts also analyzed several amino acids from rock samples brought back on the moon. More than twenty kinds of interstellar compounds have been found in the interstellar space, such as CN, CH, OH, NH_3, H_2O, HCN, CH_3OH and H_2N-CHO. What is the substance of the above forms? From the chemical point of view, they are made up of various elements. At present, there are 106 known chemical elements. The available scientific information obtained from outer space shows that the chemical elements existing on other stars are still those kinds, only in different quantities. For example, 69 elements have been found on the sun. So, can we say that the world is unified with chemical elements? Because elements are made up of atoms and atoms are made up of more elementary particles, is not the world unified with elementary particles? Because matter is infinitely separable, basic particles are not “basic” and can be
