I managed to take one optically stimulated luminescence (O.S.L.) sample at the suspected delta, as well as a few samples for grain size analysis.

我试着在怀疑是三角洲的地方带一个光释光样本，并带一些样本用于晶粒尺寸分析。

sample from the suspected delta deposit could give us information on when the landslide happened and the lake formed.

从疑似三角洲沉积物中提取的光释光样本能提供给我们信息，滑坡沉积物何时发生，湖泊何时形成。

For functions of them, the delta method implies the following result, proved in Section 14.1.4: Let denote a differentiable function of, with sample value for a multinomial sample.

为作用的他们，三角洲方法暗示以下结果，被证明在部分14.1.4：让表示一个能区分的作用，以样品价值为一个多项式样品。
