查询词典 constant

In this paper,the discharge capacity,stability voltage and the ratio of constant current charge capacity and battery discharge capacity of lithium ion battery were studied. For the lithium manganese lithium-ion batteries,the discharge capacity,mid-value voltage and stability voltage all increased with increasing charge cutoff voltage. As long as charge cutoff voltage was no less than 4.15 V,the battery discharge capacity loss would not exceed 6%. When charge cutoff voltage was 4.15V,the constant current charge capacity accounted for more than 85% of total charge capacity,a little change from 4.20 V.

主要研究了不同截止电压对锰酸锂离子电池的放电容量性能、工作电压和恒流/恒压充电容量等电池性能的影响，结果表明：对于锰酸锂材料锂离子电池，放电容量、中值电压和稳定电压都随着充电截止电压的升高而提高，电池的充电截止电压只要不低于4.15 V，电池放电容量损失就不会超过6%；当充电截止电压为4.15 V时，电池的恒流充电容量占总充电容量的85%以上，与4.20 V相比变化不大。

According to the analysis and computational results in this thesis, although the actual structure and work conditions of the pressure vessel in nuclear power station are much more complex than that of the pressure vessel model, the program FEARPV still can get quite good convergence on the plasticity andcontact iteration. And also the program FEARPV has good value stability, and good regularity. During the heating, compression, constant temperature, constant pressure, cooling and decompression process, the regularity is basically in common with that of the pressure vessel model.
