在其他的实验里，他们发现在转基因白鼠中，剔除那些制造“SP”物质的基因会降低他们得到那种疾病的概率。

In other experiments, they discovered that "knocking" out the gene that produces SP in transgenic mice lowered their chances of acquiring the condition.

当您研究这些X平方分布图时，请注意，当您在实验中改变自由度(即df)时，概率函数的形状会改变。

As you study these Chi Square graphs, note that the shape of the probability functions change when you vary the degrees of freedom, or df, in your experiment.

Murphy博士在会议上说，迄今为止，这些实验仅仅是在10万亿分之一的概率上证实了等效原理。

So far, Dr Murphy told the conference, these experiments have merely confirmed the equivalence principle to one part in 10 trillion.

In fact, you'll find the probability of this happening 3% is only about 3 percent, of it happening just by accident.

实际上你会发现,出现这种情况的概率是，所以说他们的实验结果完全是偶然的。
