一辆车跑400公里用7.87升油,一公里耗多少油
百公里耗油量：0.107*100=10.7升
每公里燃油花费：0.107*7=0.749元
结果很容易给人车辆油耗很高的印象，但这种计算方法没有考虑车辆的运行速度，也就是时速。如果车主是在一直比较拥堵的城市道路行驶，车行速度很慢，又开空调，即使290块跑两百公里也说明不了任何问题。
新规范中各级钢筋的钢筋符号分别是什么HPB300，HRB335，HRB400，HRB500
所有级别的增强钢HPB300，HRB335，HRB400和HRB500符号的新法规为：
因为[GB 50010-2010]（2015 Edition）比[GB/T 1499.1-2017]和[GB/T 1499.2-2018]的混凝土结构的设计规范（也就是说，〖GB50010-2010-（2015版））因此没有HRB600的符号。-400公里多少油钱
参考材料：〖GB50010-2010〗（2015版）混凝土结构设计规范
各个级别的钢筋钢板编号HPB300是：
参考材料：GB/T 1499.1-2017钢筋混凝土零件1：热卷曲的圆形钢条
所有级别的增强钢条HRB400，HRB500，HRB600的新法规为：
参考材料：GB/T 1499.2-2018钢筋混凝土零件第2节：热卷肋钢条
