The transmission spectrum and the absorption spectrum of alcohol shows that the characteristic absorption peak shifts with alcoholicity due to the molecular configuration. A multiple regression model was established based on the position, the intensity and the shape of the characteristic absorption peak, and used to detect alcoholicity. The predictive results show a linear relationship between predicted values and real values in sonic range, and can be used as a means to detect the alcoholicity.

通过对酒精透射光谱和吸收光谱的研究发现，其特征吸收峰随浓度不同发生漂移，从分子结构能级角度对其做了定性解释；根据部分稳定的特征吸收峰处不同波长点的吸光度，利用最小二乘法建立了多元线性回归模型，运用此模型实现了根据特征吸收峰波长的位置、强度、形状来预测酒精浓度，测定数据与样品浓度之间在一定范围呈良好的线性关系。

XRD shows: when the value of x is between 0.1 and 0.3, the alloying thin film remains the structure of hexagonal wurtzite and the angle of (002) diffraction peak becomes bigger as the value of X increases; The photoluminescence spectra at room temperature shows that the PL spectra of the alloying thin film is composed of the stronger UV emission band and weaker visible band, and UV emission peak will have the blue shift with the content of Mg increasing and the visible emission weakened.

XRD衍射测试表明：在0.1＜x＜0.3范围内，合金薄膜仍然保持氧化锌六角型纤锌矿结构，(002)衍射峰位随x的增大向大角度方向移动，在X≥0.3的范围内，合金薄膜的结构则为氧化锌和氧化镁的混合结构；室温光致发光谱表明：ZnMgO合金薄膜PL谱都是由较强的紫外发射带组成，且随着Mg含量的增加紫外发射峰位发生蓝移，同时可见发射增强。

The foundation of this system provides a good reference to promote the standardization and intelligence of the overhaul and maintenance of vacuum switches. This paper develops a special HF pulse power supply for internal pressure estimation, which achieves the output of HF-HV sinusoidal pulse wave whose frequency and amplitude can be modified respectively, and meets the design requirements according to the results of Simulink simulation and practical experiments. With the help of AT89S52, this paper designs an I~2C serial bus based signal detection system for peak value signal acquisition of HF pulse currents, which communicates with the upper computer by asynchronous serial communication for uploading the data. In the upper computer, a human computer interface is developed by Matlab software, whose functions are to do some computation and graphic display, such as calibrating the relation curve of vacuum degree and peak value of HF pulse currents, vacuum degree computation, and vacuum lifetime evaluation analysis basing on grey forecasting model as well as making relative suggestions.
