烟花的生命虽然短暂,但它尽力绽放出最美的花朵,它最灿烂的一面,就像人一样,有的人的生命虽短暂,但是有意义的,是没有遗憾的.
焰火要飞得高炸得开,效果才会好.所以,礼花弹中填充了大量用于发射以及爆炸的火药,只有这样才能达到好的表演效果.例如,一个直径为20厘米的礼花弹在发射后,要上升到大概200米的高空才会爆炸开来,让我们欣赏到五颜六色的星星点点.而这些星星点点覆盖的半径大约可以有80米左右.
  不要小看这些星星点点,它们的温度可不低.在发光发亮时,它们的温度能超过1000℃!正是在这样的高温下,礼花弹中填充的各种特制金属材料才能吸收到足够的能量,发出绚丽的光芒,这就是中学常讲的焰色反应.正是因为不同的金属原子在高温下能够放出不同颜色的光,我们才能看到颜色各异的焰火.
he life of a short while fireworks,but it tried to blossom a the most beautiful flower,it's the most brilliant side,like people,some people's life is short,but there are significant,is not regret.
Fireworks to fly high blown to open,the effect will be better.So,in a LiHuaDan filling to launch and the explosion of gunpowder,the only way to achieve good performance effect.For example,a diameter for 20 centimeters in LiHuaDan after launch,will rise to about 200 m of air will explosion come,let us enjoy colorful pinpricks.And these pinpricks of the radius of the cover about 80 meters.
Don't look down upon these pinpricks,their temperature not low.In the shine,their temperature to more than 1000 ℃.It is in this high temperatures in the various special LiHuaDan filled with metal materials can absorb enough energy,a brilliant light,this is high school often speak of the flame reaction.It is because of the different metal atoms under high temperature can emit a different color of light,we can see the fireworks of different colors.
