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.28大东集团财务部部长滕浩在举行婚礼前夕，集团595万元巨款被人利用转帐支票提走，掌管财务印章的滕浩涉嫌监守自盗。警察贾超西却将目标锁定青年企业家史哲明和滕浩挚友庄海。就在展开调查之时，史哲明身亡，庄海失踪。在随后的5年里，滕浩连遭离婚和失业的打击。他一直怀疑史哲明的死亡，为此他执着地在史哲明的未婚妻舒小凡周围寻找线索。同时她又对滕浩的郁郁不得志怀有深深歉疚，他们之间弥散着复杂的爱恨情仇。正当滕浩和舒小凡互相接受，开始真正相爱时，一个海外归来的文化人齐明宣闯入了舒小凡的生活，他不加掩饰地追求舒小凡，他的言行举止总让舒小凡似曾相识。齐明宣坦诚承认他是史哲明儿时的朋友。就在滕浩发现蛛丝马迹之时，灾难再次降临，他掉进了齐明宣精心设计的圈套，因杀人罪被判处死刑。舒小凡面对两个深爱着自己的男人，说出她走进齐明宣就是要证实他就是史哲明的事实、以还滕浩的清白！Based on BIM technology, it can dynamically display the installation of important parts in advance and provide virtual reality information for construction scheme discussion and technical exchange. Subway construction may have an impact on the surrounding buildings. BIM technology can simulate the impact of subway construction on the surrounding buildings. Combined with reinforcement technology, it can judge whether the arrangement between various components is reasonable, control the construction progress, carry out comprehensive quality inspection and observation on the construction, dynamically simulate the change trend, and put forward improvement measures.
