Pimelic acid was used as the internal satandard. All the standard samples was linear in the concentration range of 0. 0015 -0.03mol/l with good correlation (r > 0. 9997). Average recovery was 99. 32% -100.68% ( RSD = 0. 7286% - 0. 8946% , n = 6).
The technological conditions on which to prepare the standard samples, sach as ATB, ATB+W_(20)O_(58), WO_2+α-W and WO_2+β-W+α-W, are presented in this paper.
The analysis for two standard samples shows the precision s of 2.82%and 2.57%,and the accuracies of -2.34%and -5.82%respectively.

The detection limit of Cr, Fe, Cu,and Zn is below than 0.1 ng/cm~2. The standard samples used for the experiment are fromMicromatter Co. (U. S. A.)
Cr、Fe、Cu、Zn的检测下限小于0.1ng/cm~2, 标样由美国微物质公司(Micromatter Co.U.S.A.)
The experimental results of standard samples indicate that the system measurement accuracy can reach ±10 μm and the whole relative error is lower than 0.375%.
The standard samples were prepared and the properties were tested by GB1040-92 standard.
(5) We adopted the new method, which is named "equal spoke of first wave" and checked 2×2×3cm standard samples successfully, so it is possible to check the little samples.
Preparation of the Standard Samples in Quantitative Auger Analysis
The analytical results obtained by this method agreed with the methed of three standard samples. The relative deviation being within ±8%.

The function of reflectivity graph display interface is displaying the reflectivity graphs of testing samples and standard samples to provide gist for identifying and classifying of diamond color.
Through optimally selecting a group of virtual standard samples off-line, this algorithm can fulfill rapid and accurate on-line fault recognition, so it can effectively solve the problem of local convergence with FCM.
When unknown samples are analysed by this method, identification, classification and assessment can be carried out by compared the similarity of standard samples with the unknown ones.
At the same time, this system displayed the calculating results of chromatism between this testing sample and other standard samples and the the reflectivity graphs.
但是通过比较其色差计算结果发现待测样本y26与 标准样本y2的色差值要大于其与 标准样本y3的色差值，再观察反射率曲线图表明待测样本y26的反射率曲线与 标准样本y3的反射率曲线更接近。 这就表明是实验前的肉眼分类有误，本系统的测试结果是正确的。
