为了提高钢球磨煤机的工作性能和环保性,文中提出了将泡沫铝应用于钢球磨煤机筒体中,利用泡沫铝的减振降噪性能来提高钢球磨煤机的减振降噪性能。首先根据原有钢球磨煤机筒体结构初步设计了泡沫铝层合结构筒体,然后分析计算了筒体在正常运转情况下所受的载荷。利用ANSYS有限元分析软件对两种筒体进行了静、动态性能分析,得出了两种筒体的应力应变云图、前5阶模态振型图和其固有频率。最后将上述结果进行比较分析。结果表明,泡沫铝层合结构筒体具有更高的静、动态性能,从而可提高钢球磨煤机的减振降噪性能。

This paper presents the results of research on the application of inverter in the grid connected solar photovoltaics (PV) system. The main content of the article is to control the three-phase grid connected inverter to meet the requirement of controlling the reactive power to zero at a node of the distribution network while maximizing the active power transmitted to the grid. The control circuits are synthesized on the dq coordinate system and verified on the simulation model by Matlab/Simulink. Both simulation and experimental prototype on 5 kW inverter, being connected to low voltage grid, have been built to show the good results and the practical readiness for implementation.

Er^3- / Yb^3＋ co - doped silica - alumina monolithic xerogels were prepared with the same concentration on 2 000 Er/Si ppm and 6 000 AI/Si ppm. The Yb/Si content was varied from 0 to 4 000 ppm. Densification of the samples was achieved by thermal treatment in air at 950 ~C for 120 hours with a heating rate 0.1 ~C / min. Photoluminescence spectroscopy was used to obtain information about the effective excitation efficiency of Er^3＋ ions by co-doping with Yb^3- ions. The infrared-to-visible up-conversion luminescence has been investigated upon continuous wave excitation at 980 nm. The samples exhibit red, green and blue upconversion emission. It is found that the intensity of up-conversion luminescence increases with increasing Yb3- doping concentration. An opposite behavior is observed for the 4 I13/2 luminescence of the Er^3＋ ions.
