按下左图装置预先收集好氧气和氢气各一塑料袋,为了便于用一手操作,两个袋要放在一起。操作时先打开弹簧夹1,用手轻轻挤压氢气袋,使玻璃吹管中空气排尽,然后点燃吹管,玻璃吹管尖端的内径要在1.0—1.5mm之间。可见氢气在空气中安静地燃烧,放一铁片,铁片不被烧熔。打开弹簧夹2,轻轻挤压氧气袋,发现火焰明亮,根据火焰的明亮程度,可适当调节
Press the device on the left to pre-collect a plastic bag of oxygen and hydrogen. To facilitate the use of one hand, the two bags should be put together. When operating, open the spring clip first, gently squeeze the hydrogen bag by hand to exhaust the air in the glass blow tube, and then ignite the blow tube. The inner diameter of the tip of the glass blow tube should be 1.0-1.5 mm. It can be seen that hydrogen gas is burned quietly in the air, an iron piece is placed, and iron pieces are not melted. Open the spring clip 2 and gently squeeze the oxygen bag to find that the flame is bright. Adjust it according to the brightness of the flame.
