REPORTS FROM THE BOARD

摘要

BIPM was originally created to be a scientific institution with responsibility for the coherence and consistency of the world measurement system, traceable to the International System of Units (SI). Initially this focused strongly on length and mass but, over the first 30 or so years of its life, BIPM's technical work grew steadily to cover temperature, electricity and photometry. Ionizing radiation and time characterization came much later and an activity in chemical metrology has been with us for only about five years. The scientific programme is ever-changing with large areas disappearing as BIPM's job is done, but being replaced by new projects designed to meet the needs of today's metrology community. BIPM is accustomed to change-something which makes it a lively and interesting place in which to work as well as keeping us on our scientific toes. Scientific work is at the heart of what we do, and gives us a technical credibility, but it is far from all we do.
