试验一组电解槽时,其结构和工艺特点对槽寿命指标影响的最充分资料,可以在该组电解槽停槽后得到。若电解槽的试验时间很长,有必要在只切断部分电解槽时(未完成试验或分段试验)来评价寿命指标。抽取未完成试验的结果所得到的随机值称为分段抽样,这样,要区别开一次分段抽样和多次分段抽样。一次分段抽样的试验是:将一组的全部电解槽都在同一时间起动,即在分析时,一些电解槽被切断,而其余电解槽具有同样超过被切
When testing a set of electrolyzers, the best information on the effects of structure and process characteristics on the life of the bath can be obtained after the set of electrolyser stops. If the electrolysis cell test time is very long, it is necessary to cut off part of the electrolyzer only (unfinished test or sub-test) to evaluate the life of indicators. The random value obtained by taking the result of an unfinished test is called a piecewise sampling, so that the piecewise sampling and the piecewise sampling are differentiated. A sub-sampling test is to start all of the cells in a group at the same time, ie during the analysis some electrolysers are switched off and the remaining cells have the same power
