absorptive power वाक्य

After a decade of field and greenhouse tests, a variety of techniques harnessing the absorptive power of plants'roots appear poised for a much expanded role.
In 1858, Balfour Stewart described his experiments on the thermal radiative emissive and absorptive powers of polished plates of various substances, compared with the powers of lamp-black surfaces, at the same temperature.
These yielded a remarkable extension of Pierre Pr�vost's " Law of Exchanges, " and enabled him to establish the fact that radiation is not a surface phenomenon, but takes place throughout the interior of the radiating body, and that the radiative and absorptive powers of a substance must be equal, not only for the radiation as a whole, but also for every constituent of it.
