1、rate of change of momentum of the air is allowed for by apparent mass components, the magnitudes of which must be determined experimentally.───空气动量的变化率可用表观质量分量描述,这些分量的大小必须通过实验来确定。
2、Regardless of hysteresis of air system, the main factor that influences dynamic response of fuel cell is diffusion concentration polarization, which restricts the change rate of stack current.───不考虑空气XiTong的时间滞后,影响电池动态响应时间的主要因素为扩散浓差极化,它限制了电流的变化率。
3、calculation models of the effective area, the rate of change of the effective area and the rate of change of the effective volume are established for the diaphragm air spring.───膜式空气弹簧结构与计算模型的基础上,建立起膜式空气弹簧有效面积、有效面积的变化率及有效体积变化率的计算模型。
