发光体
By using the silica window which achieved thermal equilibrium in the liquid steel as the luminous body, the immersion temperature measurement was carried out and errors resulting from the surrounding perturbation ( i. e., dust and vapor) were decreased.
该高温计利用和钢水达到热平衡的石英玻璃窗作为发光体,实现浸入式测温,减少了环境干扰(如灰尘、水汽等)带来的误差。
