1943年日本侵华战争处于相持阶段，敌人实施三光政策，对我华北地区疯狂扫荡。八路军大部队与日军殊死搏斗，以赵大胆为首的赵家庄民兵队却误把八路军埋下的地雷挖走，闯下大祸，民兵队面临解散。Enter the flight simulator. Using flight simulatorsCode as above; Write three functions of order500, order200 and orderNormal respectively, and process their own business logic in the functions respectively. If their own functions cannot be processed, they will return the string nextSuccessor to pass it back, then encapsulate the constructor Chain, pass an object fn into it, and have their own attribute Successor. There are two methods setNextSuccessor and passRequest on the prototype. The method setNextSuccessor specifies the order of nodes in the responsibility chain, and saves the corresponding method to the attribute this.Successor, chainOrder500. SetNextSuccessor (chainOrder200); ChainOrder200. SetNextSuccessor (chainOrderNormal); Specifies the order in the chain, so this.Successor references the order200 method and the orderNormal method, so if chainOrder500.passRequest (1, true, 500) is called for the first time, the order500 method is called, output directly, and chainOrder500.passRequ is called for the second time.20岁的茉莉因患病被告知仅剩10年寿命。为了不对活着这件事抱有执念，她决定不再恋爱。直到她在同窗会遇到了和人...Therefore, learning design patterns, The first thing to do is to understand which aspects of design patterns are available to developers, Then, the principle, timing and method of each design pattern are studied respectively, that is to say, under what circumstances should a certain design pattern be used? When understanding the timing of a certain design pattern, it is also necessary to understand what consequences will be caused if this design pattern is not used at this time. After understanding the principle and usage of each pattern, more importantly, learning the object-oriented thinking mode, after mastering the object-oriented thinking mode, looking back at the design pattern, you will have a deeper understanding. Finally, learning the design pattern, you must study hard and practice more. "I agree with the last sentence very much."故事讲述欠债父亲13年后再次现身，却已身患癌症，时日不多。直到父亲的告别仪式上，才从前来祭拜的人们口中了解真实的父亲。"Er... I really can't remember the model, it's green, probably so thick." Wang Zeduan could not remember the specific model of the explosive cylinder, Just said the color and gesticulated the approximate size with his hand, Later, I looked up the information and learned that The detonators used at position 142 were all Type 68 detonators, This is also a classic explosive barrel widely used throughout the Sino-Vietnamese border war. This type of explosive cylinder is 60 centimeters long each, As long as there is a need, it can be spliced indefinitely. The charge for each section is 2.2 kg, According to Wang Zeduan's description, At that time, the explosive barrel was made up of three sections. Then the total charge is as high as 6.6 kg, However, the high explosive bomb used in the type 66 152 mm howitzer, The charge is 6 kg, In other words, The charge of these three explosive cylinders is 0.6 kg higher than that of a 152 mm grenade. This is also basically in line with his description that it is more powerful than a shell. In addition, after being inserted into the ground, the two sections of the upper half form a certain blast height from the ground, In this way, the explosive power can be better exerted virtually to cover a wider area, so it is indeed reasonable that an explosive barrel can successfully achieve the tactical purpose of successfully clearing position 142 for the second time (the first clearance is 66-type directional anti-infantry mines and 72-type pressure/tripping anti-infantry mines).
