I am not exactly sure what you need help with. The grammar or the meaning of the sentences so I will explain both.
First when you have by followed by the gerund, it is an experssion used to explain how something was done or accomplished.
For example my monthly bills have decreased. How did they decrease? My monthly bills were decreased by shutting off lights, by using less water and by cancelling my cell phone.
So for each of the sentences it is explaining how something was done.
How can you helpme? By translating...
How did Winkler prepare the tetraethylgermane? He did it by treating...
How was the quality estimated? It was estimated by distilling...
How was the solution diuted? It was diluted by pouring...
Does that help?
Have a great day.
