SOLUTION<br />
We believe that a necessary condition for the solution <strong>of</strong><br />
the above-formulated problem is the use <strong>of</strong> newly-<br />
developed ground calibration facilities:<br />
• Highly accurate blackbody sources on the basis <strong>of</strong> phase<br />
transitions <strong>of</strong> eutectic alloys and pure metals that<br />
possess very high reproducibility; such sources on<br />
eutectic alloys were first advanced by the National<br />
Institute <strong>of</strong> Metrology <strong>of</strong> Japan.<br />
• Improved calibration installations<br />
