求翻译：铁谱分析发现油样中含有大量来自轴瓦的有色合金和轴颈的钢铁磨损颗粒，见图2。发射光谱测出该样品的钠和钙含量很高，主要来自水泥颗粒。是什么意思？

The iron spectrum analysis of oil samples containing a large number from the bush colored alloy steel and journal wear particles, as shown in Figure 2. The emission spectra measured sodium and high calcium content of the samples, mainly from the cement particles.

Mass spectrometry analysis revealed that iron in the sample with a large number of bearings from ferrous alloys and the Journal of the iron and steel wear particles, see figure 2. Launch the sample spectra measured sodium and calcium content is very high, mainly from cement particles.
