求翻译：确定脱气时间后，再取3份质量为5000.0mg，粒度＜0.5mm的煤样进行脱气温度实验，脱气温度依次为125℃，175℃和200℃，加上脱气时间中设置的150℃实验，脱气温度实验可以看成有四组是什么意思？

OK degassing time, and then take 3 parts by mass 5000.0mg, particle size <0.5mm degassing of coal samples temperature test , degassing temperature were 125 ℃, 175 ℃ and 200 ℃, plus degassing time set

Determine and air time, and then the 3 QUALITY OF 5000.0 mg, the granularity <0.5 mm of coal as a Temperature Experiment, temperature, in turn, is 125 degrees C, 175 °C and 200 degrees C, and degassing time set in the 150 Degrees C experiment, and temperature experiments can be seen as a group 4

After the determination degasification time, then takes 3 qualities is 5000.0mg, the granularity <0.5mm coal sample carries on the degasification temperature experiment, the degasification temperature is in turn 125℃,175℃ and 200℃, in addition degasification time establishes 150℃ the experiment,

Determine the degassing time, then take 3 quality of 5000.0mg, off the coal particle size <0.5mm temperature experiments, and temperature is 125 degrees, 175 and 200 ℃, 150 ℃ experiment of the degassing time set, take off the temperature experiment can be seen as there are four
