I nodded at this passage, Understand that what Zhang Xiaobo said is indeed reasonable, It is not a lie, Here I think it is necessary to give you one thing about popular science. So we have to say something digressive: The result of a real bullet hitting a petrol tank is not the same as that shown in most movies. One shot can explode the petrol tank, But this is not the case, Although a pure metal projectile will rub against the air at a speed of hundreds of meters per second to generate equivalent heat, And will produce sparks after hitting the metal oil drum, But none of this is enough to ignite petrol, Especially for gasoline with a large total amount, to ignite gasoline, please remember one thing-open flame must be used. In addition, gasoline is a flammable item, but it is not an explosive item in the true sense. Only after reaching a certain total amount can explosion be caused. If the total amount is insufficient, it can only cause combustion without explosion.一席话下来，黄豆满脸崇拜地看着黄观道：这个哥哥好有文采，我听明白了。Return context.getNum1 () + context.getNum2 ();周星河这部电影和现在的电影，风格截然不同，换成其他有主见的导演，指不定会坏事。秦淼则委屈地嘀咕道：葫芦哥哥跟板栗哥哥也真是的，都没认出咱们。Http://www.freebuf.com/articles/neoppoints/152457.html
