During the measurement, the immersion period of the sublance in the molten steel should not exceed 8 seconds.

测量时要按要求控制好探头在钢水中停留的时间，一般不大于8秒。

The electrochemical impedance spectra changes with extended time clearly. Capacitive impedance increases in early immersion period.

同时整个浸泡过程中，体系的交流阻抗谱也发生了明显的变化。

Two separate periods are identified:the iron shell period and melting period, after immersion of ferrosilicon into liquid iron.

结果表明：硅铁浸入铁液至完全熔化分为两个时期，即铁壳期和熔化期；

In fact, during the most recent rally, Immersion has been walking the upper bollinger band (10-period setting) for the most part, affirming that the trend may continue.
