First, there is exhaust gas leakage from the external engine and foreign matter in the air inlet, which leads to unpleasant smell from the air inlet of the air conditioner. In this case, it is very good to check and go to the repair shop to open the cover for inspection, which can be clearly seen. Second, the air conditioning filter element is too dirty. Regular cleaning and inspection can completely prevent the occurrence of peculiar smell. Third, the air conditioning pipes and evaporators are caused by mold, which is also more troublesome and expensive to maintain. The first two situations are relatively simple and easy to check. The following focuses on the third reason, why mold can be produced in pipelines and evaporators. The following master will give you a brief introduction.从今日宴会上边可见一斑，张良并不曾多说几句，套用一句不太恰当的俗语咬人的狗不叫，郦食其虽能舌灿莲花，滔滔雄辩之能，尹旭却并不放在眼里。　　全高云([小公女])执导的短片[亲吻是罪]围绕两个发誓要甜蜜复仇的女孩展开；该剧记录了广州老城区西关一户姓康的人家，老俩口生有四个儿子，依着老康的如意算盘，未来媳妇应该都是广州本地姑娘，但恰恰相反，三个儿子的意中人却都是来自外地女子，其中一个还是金发碧眼的“鬼妹”。康家原有的生活秩序被打乱了，一个带有新鲜内容和喜剧色彩的家庭生活展现在我们面前：老头子对外来人的固有偏见；二儿媳妇自认为是正宗的广东人，争宠夺势；岭南文化与北方文化的冲撞交锋；两个外来媳妇本身之间的地域性格差别；以及这种特殊的婚姻组合所带出的整个珠三角地区的社会生活新变化，展现了广州正向着更为广阔的国际空间发展。The above is only a model of "Long En" bicycle, If you need to generate other types of bicycles, Other subclasses can be written. The most important advantage of factory mode is that some of the same methods can be implemented. We can write code in the parent class for these same methods. If we need to implement specific business logic, we can rewrite the parent class's methods in the subclass to implement our own business logic. In terms of professional terms, there are two points: First, weaken the coupling between objects and prevent code duplication. Instantiating a class in a method eliminates repetitive code. Second: Repetitive code can be written in the parent class. Subclasses inherit all member attributes and methods of the parent class. Subclasses only focus on implementing their own business logic.
