极限电流 meaning in Chinese
carrying current
limited current
limiting current
Examples
- Limiting no damage current
不溶极限电流 - The flow characteristics , distributions of current density and chemical components , and the performance of these two different designs are calculated and compared . the flow and mass transport characteristics are analyzed in detail , which indicate that strong forced convection is produced in the interdigitated flow field , which consist of dead - end gas channel that force the gases through the porous electrodes . results of comparison show that forced convection induced by the interdigitated flow field in the diffusion layer effectively enhances mass transport of reactants and products , thus leading to a higher cell performance and the limiting current density
在传统流道设计的pemfc中，反应物从流道到催化层的供应和生成物从催化层到流道的排出主要是以扩散为主，而在交叉梳状流道设计中，以流动带动的对流传递则占据了主导地位，而且这种以对流为主的传递机理大大提高了反应物和产物传递速率，从而有效地改善了电池的极限电流密度和极化性能等特性。 - According the key factors we find , we bring forward a new conception : multilevel suppressor and design a new high performance suppressor whose ion - exchange membrane has bigger areas and using three electrodes including one cathode ( anode ) and two anodes ( cathode ) , at the same time we fill the suppression compartment with one kind of ion exchange resin which has moderate exchange capacity . according to our experiment ' s results , we find the new type suppressor has quite high working current efficiency and suppressing capacity . in most cases , the suppressor ' s current efficiency is over 90 % ; the suppressor can transform the naoh ( concentration : 200mmol / l , flow rate : i . oml / min , conductance : over 10000 i - i s cm " ) to pure water ( conductance : 8 . 9 it s cm in chapter 3 , the high performance suppressor is applied in determination some trace - amounts ions in plating solution , sewage . in this chapter , we also have a research on the gradient ion chromatography
第二章首先以xyz - 1型电化学抑制柱为例，分析了电化学抑制柱的抑制过程得出影响抑制容量的主要因素主要是抑制柱的电流效率和离子交换膜的极限电流密度，因此采用中等交换能力的离子交换树脂作为抑制室的填料以提高电流效率，在通常情况下电流效率可达到90以上；在选用同种离子交换膜的前提下，可通过增加离子交换膜的有效面积达到提高极限电流的目的从而提高抑制柱的抑制容量，因此提出了多级抑制的概念并据此研制了共电极式高容量电化学抑制柱，该抑制柱最高可将流速为1 . 0ml / min ，浓度为200mmol / l电导率超过10000 s ? cm ~ ( - 1 )氢氧化钠溶液抑制为电导率低至8 . 9 s ? cm ~ ( - 1 )的纯水，并且具有稳定性高、分析结果准确等优点。
