从天才的俄国学者Д.И.门捷列夫发现基本的自然律之一——周期律——的时候起,已过了八十多年了。将来周期律不会有消灭的危险,而只有丰富和发展的希望;周期律创立者的这些预言是完全被证实了。在原子结构的研究中以及後来在原子核的研究中,周期律都起了基本的作用。和周期律密切相联系的,还有在实验室的条件下用人工创造新元素的研究工作。 More than 80 years have passed since the talented Russian scholar Д.И Mendeleev discovered one of the basic laws of nature - the periodic law. In the future there will be no danger of annihilation, but only hope of enrichment and development; these prophecies of the cyclical law creators are fully substantiated. Periodic law plays a fundamental role in the study of atomic structure and later in the study of the nucleus. Closely related to the periodic law, there is also the work of creating new elements by hand under laboratory conditions.
