The dual-function materials could make E. V. 's and hybrid vehicles lighter as they simultaneously provide extra electricity.
这种双功能材料能使电动汽车和氢能车更轻，同时提供额外的电力。
Results: Determine the end-point of titration by sudden potential change of the indicatory electrode (use E-V curve method).
结果：指示电极电势突变时，为滴定终点(选用e V曲线法)。
