One problem with the factory method pattern is that the creation of the class depends on the factory class, that is to say, if you want to expand the program, you must modify the factory class, which violates the closure principle. Therefore, from the design point of view, there are certain problems, how to solve them? We use the abstract factory mode to create multiple factory classes, so that once new functions need to be added, we can directly add new factory classes without modifying the previous code. Because the abstract factory is not very easy to understand, let's look at the diagram first, and then it is easier to understand with the code.估计最轻也是流放，你们全家都逃不掉。Added flap adjustment F F-儿女们长大了，老人苏世坤和相依相伴的老伴范淑贞历尽沧桑，在不尽的风雨中变老了。 　　作为力学研究院高级顾问的苏世坤，虽已年近七旬，却一天到晚忙忙活活。为这事，老伴和孩子们不止一次劝他“累了一辈子了，也该歇歇，享几年清福了！”但苏世坤却不这么认为，总是说，“人越老越不能闲着，不干事，人就闲坏了，越老越得有点事干，有事干了，才充实……，他还说，人老了，就像一台老机器一样，如果它每天都在运转，就不会报废，如果让它闲置在一边，不再运转了，恐怕用不了几个月，这台机器就会像一堆锈迹斑斑的废铁疙瘩，再也转不起来了……”。 　　眼下，五个儿女都已经长大了，陆陆续续成家立业，按理说，两个老人已经基本完成任务，该过几天安稳日子了，可说不清怎么回事，总是摁下葫芦，瓢起来，这些个儿女们几乎没有一天让老人省过心。 　　儿女们当中，可以说二女儿苏文静是最让两个老人操心的一个闺女了。 　　苏文静这闺女从小又机灵又皮实，可就是学习跟不上趟，几乎年年补考。就是这么一个孩子，却能从初一就和一个叫赵树彬的男同学开始谈恋爱，一故事从主人公乔迪好友李秋来的婚礼上开始，讲述了李秋来在婚礼现场放弃了乔迪与老婆为他介绍的未婚妻，并火速迎娶了漂亮的导游为妻。对此，乔迪的老婆刘佳诺心中十分不悦，一直为自己“被逃婚”的朋友感到不平。并把这些怒气及生活中的琐碎毫无保留地发泄到了老公乔迪身上。从此一场新时代的夫妻大战拉开帷幕，就此展开的故事精彩纷呈，家长里短贴近现代人婚姻生活被赵会南诠释的生动到位。Know the principle + can change the model details man: if you come to this step, congratulations, get started. For anyone who does machine learning/in-depth learning, it is not enough to only understand the principle, because the company does not recruit you to be a researcher, when you come, you have to work, and when you work, you have to fall to the ground. Since you want to land, you can manually write code and run each familiar and common model, so that for some businesses of the company, you can make appropriate adjustments and changes to the model to adapt to different business scenarios. This is also the current situation of engineers in most first-and second-tier companies. However, the overall architecture capability of the model and the distributed operation capability of super-large data may still be lacking in the scheme design. I have been working hard at this stage and hope to go further.在一场巨大而神秘的事故之后，一位年轻有才华的建筑师在一个与现实世界相似的奇异世界里苏醒，这个世界建立在这里人民的记忆之上，而这些人则处于深度昏迷之中。由于这些人的记忆力参差不齐、混乱、不稳定，导致奇怪的记忆和回忆——城市、冰川、河流可以共存在一个房间里，所有的物理定律都可以被打破，建筑师必须找到他们昏迷的具体规律，才能找到通往现实世界的出口。就在他与命运抗争的同时遇到了真爱，而经历此次昏迷之后，他发现自己不得不重新认识这个世界……
