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.纪录片《花开中国》拍摄周期两年，花开花落，行程足迹遍及中国21个省市自治区，深度调研及拍摄走访了英国、法国、美国、日本、荷兰等国家近20个城市，只为追本溯源，探索中国花卉文化的传播发展历程。 本系列共5集，每集50分钟，选择了五种中国人耳熟能详的花卉：茶花、杜鹃、月季、菊花和牡丹。从山野到园林，从中国到世界，花虽无言，却用美连接起不同地域的文化和生活。In real life, China's income tax is divided into enterprise income tax, foreign-invested enterprises or foreign-invested enterprises income tax and personal income tax. For these three types of income tax, each is calculated in a different way. Personal income tax has a personal income tax calculation method, while enterprise income tax has its corresponding calculation method. If we do not adopt the policy mode to realize such a requirement, we will define an income tax class, which has an attribute to identify the type of income tax and a CalculateTax () method to calculate the tax. In this method, we need to judge the tax type and calculate the income tax for different tax types through if-else statements. Such an implementation can indeed solve this scenario, but such a design is not conducive to expansion. If the system needs to add an income tax in the later period, it has to go back and modify the CalculateTax method to add an additional judgment statement, which clearly violates the principle of "open-closed". At this time, we can consider using the strategic mode to solve this problem. Since the tax method is the changing part of this scenario, we can naturally think of abstracting the tax method at this time, which is also the essence of the implementation of the strategic mode.辽沈战役酣战之际的年10月，国民党反动派对我解放区石家庄实施了一次代号“穿心行动”的奇袭计划，妄图一举击毁我党中央“心脏”西柏坡。刚刚解放一周年的新城市石家庄城内，一场波谲云诡的生死对决就此展开。该剧讲述了家庭主妇白莹莹在发现丈夫丁志远出轨了自己闺蜜顾菲儿后，对婚姻生活心灰意冷，而后发现六年前妹妹白晶晶自杀身亡的诸多疑点，在躲过顾菲儿的追杀后，在江川、金瑞等朋友的帮助下，开启事业新篇章的故事。　　故事的舞台是清兰学园仍在举行的学园第一美男美女的选美大赛。憧憬着选美大赛的平凡女高中生的主角，一边抱着外表的烦恼，一边对抗着在校园内留下深刻色彩的外表主义，为梦想和恋爱而奋斗的逆袭爱情故事。这是刘邦不希望看到的局面，也不容许出现的局面。
