“在调查研究中”可以翻译为 "in the process of investigation and research" 或者更简洁地表达为 "during investigation and research"。
例如：
We discovered many valuable insights in the process of investigation and research.（在调查研究中，我们发现了很多有价值的见解。）
During investigation and research, we gathered a wealth of data.（在调查研究中，我们收集了大量数据。）
