CRC 物理化学手册84版完整整理版

The 84th Edition of the CRC Handbook of Chemistry and Physics continues the overall philosophy of this work, namely, to provide broad coverage of all types of physical science data commonly encountered by scientists and engineers. Notwithstanding the growing availability of specialized databases on the Internet, we feel there is still a need for a concise, reliable reference source spanning the full range of the physical sciences and focusing on key data that are frequently needed by R&D professionals, engineers, and students. The CRC Handbook, in its print, CD-ROM, and Internet formats, is aimed at serving these needs. The data contained in the Handbook have been carefully evaluated by experts in each field; quality control is a high priority and the sources are documented. The annual updates make it possible to add new and better data in a timely fashion. In this way we hope to continue the role of the CRC Handbook as a unique reference source.
