That is within the accuracy limits of the dating techniques themselves.

这在年代测定技术本身的精度范围内。

But this was before scientists had really perfected their dating techniques for things that old.

但这是在科学家们真正完善他们对那些古老事物的约会技术之前。

Consequently, researchers have had to develop new dating techniques appropriate to its geology.

因此，研究人员不得不开发适合其地质的新测年技术。

I’m going to talk about a particular dating technique. Why? Good dating is a key to good analysis.

我要谈谈一种特殊的约会技巧。为什么？良好的约会是良好分析的关键。

Pieces that had been on public display can now be tested using new dating techniques, says Dr Helwing.

赫尔温博士说，现在可以使用新的年代测定技术来测试曾经公开展示的作品。

But the current find involves new excavations and a dating technique that turned the clock back past 300,000 years.

但目前的发现涉及新的发掘和一项将时钟拨回 30 万年前的测年技术。

Some of the tools were cracked as if they had been heated, and that opened them up to a dating technique known as thermoluminescence.

一些工具出现裂纹，就好像它们被加热了一样，这为一种称为热释光的测年技术打开了大门。

A sophisticated dating technique, called cosmogenic nuclide dating, has upended previous estimates—and, with that, is rewriting an important chapter in the story of human evolution.

一种称为宇宙成因核素测年的复杂测年技术推翻了之前的估计，并由此改写了人类进化史的重要篇章。

A special optical dating technique helped pinpoint the likely age of the DNA. It scoured single grains of sediment for varying exposure to light over the course of millennia.

一种特殊的光学测年技术帮助确定了 DNA 的可能年龄。它在几千年的过程中冲刷了单粒沉积物以改变光照。

Established methods of putting ages to hominin fossils rely on dating layers of volcanic ash above and below the strata in which they were found, using the uranium-lead method, one of the oldest and most refined dating techniques.

确定古人类化石年代的既定方法依赖于使用铀铅法（最古老和最精炼的测年技术之一）在发现它们的地层上方和下方的火山灰层测年。
