(1) Any of a series of chemically similar, radioactive elements with atomic numbers ranging from 89 ( actinium ) through 103 ( lawrencium ).

(2) The temperature distributions of the flow field measured by two-platinum lawrencium thermocouple certify that the heating scheme by counter flow mixing is basically feasible.

(3) No more will the creators of a new element be able to name it after a famous scientist( lawrencium), city( berkelium ), or sate( californium).

(4) Actinide: Any of the series of 15 consecutive chemical elements in the periodic table from actinium to lawrencium (atomic numbers 89-103).
