I do not know how many people are ready to start their low-carbon style, and how many enterprises have begun to re-measure their production and management by using of the carbon emission.

我不知道有多少人准备好现在开始自己的低碳生活、又有多少企业开始用碳排放来重新衡量自己的生产和经营。

Rare earth elements and thorium in RE-Nb-Ta ores were determined by inductively coupled plasma-atomic emission spectrometry (ICP-AES).

用等离子体发射光谱法测定了稀土铌钽矿中的稀土元素和钍量。

In addition to technical means, re-optimizing the allocation of resources is an important way to achieve the energy saving and emission reduction in power generation industry.

除了技术手段之外，资源的优化重组也是实现发电行业节能减排的一个重要途径。

So, let's say we're looking at an element and we have an emission spectra, and we know that it has five distinct different kinetic energies in that spectrum.

比如我们正在研究一个元素,而且我们得到了它的光谱，知道了在它的光谱里,有五个分立的动能。

we start high and go low, we're dealing with emission where we have excess energy that the electron's giving off, and that energy is going to be equal the energy of the photon that is released and, of course, through our equations we know how to get from energy to frequency or to wavelength of the photon.

当我们从高到低时，我们说的,是发射,电子有多余的能量给出，这个能量等于，发出,光子的能量，当然我们可以通过方程,从能量知道，光子的频率，和波长。
