Табличные пределы КТ позволяют рассчитывать излучение абсолютно черного^тела в видимой и инфракрасной областях спектра при температуре Пример 5. Для абсолютно черного тела с температурой t = 227° С (7 = 273 + т 227 = 500 К) требуется найти спектральные плотности излучения в относительных и абсолютных единицах при длине волиы Я. = 3 мкм, а также суммарные плотности излучения в спектральном интервале = 2 ыкы...Хд = - 4 мкм для обычной и логарифмической шкал длины волны. Решение. I Определяем аргументы для входа в табл. 2.15. соответствующие iWHHaM воли 1 = 3, Яг = 2 и Ха = 4 мкм: -iT 3.10-4,500 = 0,15; г^Г^ 2-10-4.500 = 0,10 и КаТ = = 4.10-4-500 = 0.20 см. К.
