known sample

The known sample is not large enough to determine a firm upper mass limit, which would in turn give more detailed insight into the physics of such extremely dense forms of matter.

这些已知的样本还不足以确定一个严格的质量上限，而这个上限可以帮助我们进一步了解这些极高密度的物质的物理特性。

After the mass fractionation of the original Re isotope data, combined with the isotope dilution formula, the Re isotope data was obtained. The quality of the data was controlled by the known sample and international standard sample.

Re同位素数据经过分馏校正后，结合同位素稀释公式，计算出样品的Re含量和同位素组成。

However, the first ever known sample of a visiting card, dating back to1786, was found in Germany.

不管怎样，有记录的第一张名片1786年出现于德国。

However, the first ever known sample of a visiting card, dating back to 1786, was found in Germany.

不管怎样，人们所知道的第一个拜访卡样本－追溯到1786年－出现于德国。

The early-warning model can distinguish the known sample data completely. After the preliminary use, the early-warning model can accurate distinguish almost the unknown sample data.

预警模型对已知的样本数据可以完全判别，在初步使用后对未知样本数据的基本判断准确。

But under normal circumstances, it is impossible to get the theoretical weight function by a finite number of known sample points.

但是一般情况下，通过有限个已知样本点求理论权函数是不可能做到的。

The known sample values are used to estimate the value of the next sample time, and the actual start or stop of the voltage sag are confirmed by detecting how much the actual values deviated the predict values.

利用已知的电压采样值预测下一采样时刻的电压采样值，通过检测实际值和预测值的偏差判断电压扰动的起止时刻。
