That meant participants were randomized into experimental or control groups, and that both participants and experimenters were blind to which experimental condition they were in.

这意味着参加者被随机分为实验组组，参加者和实验者都他们所处的实验条件一无所。

As such, we can study cells grown in special dishes that allow us to test hundreds of experimental conditions at a time.

因此，我们可以研究在特殊培养长的细胞，这些培养允许我们一次测试数百种实验条件。

This meant that in a day's work, I could really only test five or six different experimental conditions to see how the cells responded.

这意味着在一天的工作，我实际上只能测试五六个不同的实验条件来观察细胞是如何响应的。
