time for individual study的意思|示意

Like I said before, ULD has been with us for a while but until recently, in order to do it, you really had to study many individual grains and it took a long time before you got results.

正如我之前提到的，ULD已经产生了很长时间了，但是直到今天，为了使用它，你必须要研究很多个体砂石，而且要等待很久才能得到结果。

The idea is that when individual know they are part of a study, their productivity automatically increases regardless of other factors, such as how much time or money they are given, for example.

这个观点是指当个体知道他们是研究小组的一部分时，他们的生产率不受比如他们被给定的时间或金钱其他因素影响，自动地提高了。
