The long-term trends of these thermocouples are used to monitor the activity characteristics and aging of the catalyst. The fraction of the catalyst bed’s full temperature rise occurring at each level is a direct indication of the fraction of the total ethylene reaction that has taken place below that thermocouple level. What does “characteristics” mean in this sentence?
Activity characteristics and aging of the catalyst – does this refer to the catalyst’s activity as well as its aging (deactivation) process? I think \"characteristics\" should be translated as \"properties\"
To monitor the activity characteristics and aging of the catalyst. To observe the activity (properties) and aging of the catalyst.
activity characteristics can be translated as “activity” here”
Please try to translate it by yourself first.
It’s been translated, but I’m not entirely sure!
Please post what you have translated, and also mark the parts where you are unsure. Is it that someone has to help you answer questions, and they even have to ask you repeatedly – is it really that troublesome?
