科技数据是人们从事科研和生产活动不可缺少的技术性资料。尤其在当今“知识爆炸”的时代,数据的利用显得更为重要。各学科间的交叉和新学科的建立无不伴随着诸学科数据交互使用和大量新数据的产生,实验数据和数值计算在科学文献中的比重也日趋增大。伴随着这种进展的是。一大批侧重收集数据的新型工具书相继涌现。一些历史悠久、负有盛名的工具书,如美国CRC公司编辑出版的《化学与物理手册》(Handbook 0f Chemistry and Physics),也尽可能地在保持原有特色的同时,广为收集和扩充有关常数、参数等 Scientific and technical data are indispensable technical materials for people to engage in scientific research and production activities. Especially in today’s “knowledge explosion” era, the use of data is even more important. The interdisciplinary interdisciplinary and the establishment of new disciplines are all accompanied by the interactive use of various disciplines and a large amount of new data. The proportion of experimental data and numerical calculation in the scientific literature is also increasing. With this progress is. A large number of new reference books focused on data collection have emerged. Some historic and well-known reference books, such as the Handbook of Chemistry and Physics edited and published by the CRC Company of the United States, also try their best to collect and expand relevant information Constants, parameters and so on
