“…Since f cannot represent itself as a good measure of self-absorption, we calculated line transmission (t in Table 3) due to self-absorption as was previously described in our work. 50 The plasma conditions for such calculations were T ¼ 0.8 eV, N e ¼ 2 Â 10 17 cm À3 , and optical length ¼ 0.1 mm i.e., typical conditions for plasma produced by the LE HRR DPSS laser at early stages. 51 Contents of analytes were the same as in OOPE 604.…”

“…Соответственно для каждой экспериментальной точки были рассчитаны значения α при трех температурах: среднем значении T и на границах доверительного интервала (p = 0.95). Так, при изменении температуры с 7100 до 8500 K α изменяется от 70 до 92% в случае Li и от 20 до 70% для Mg. Таким образом, в условиях нашего эксперимента доля незаряженных атомов (1 − α), излучающих на выбранных нами аналитических длинах волн, оказывается небольшой и заметно зависимой прежде всего от температуры плазмы, что хорошо согласуется с данными моделирования спектров плазмы [15]. Таким образом, погрешность оценки температуры вносит большую неопределенность в результат расчета состава образца.…”
