锅炉受热面管的复合涂层防护技术

针对燃煤电站锅炉受热面管磨蚀严重，导致泄露、爆管等事故而被迫停炉检修的情况，根据受热面管的形状、工况条件和使用环境状况，对电弧喷涂工艺以及对若干用于锅炉抗高温磨蚀的喷涂丝材所制备涂层的微观组织结构、硬度、涂层结合性能以及耐冲蚀磨损性能和高温腐蚀性能等进行了深入的研究。结果表明，以超音速电弧喷涂NiAl丝材作为结合底层、金属-陶瓷材料或高Cr材料作为功能层、并辅以高温封孔的复合涂层制备技术，可提高锅炉运行的可靠性和经济性。     

Ultraviolet-visible and surface-enhanced Raman scattering spectroscopy studies on self-assembled films of ruthenium phthalocyanine on organic monolayer-modified silver substrates

A self-assembled film of ruthenium phthalocyanine (RuPc) fabricated on a silver substrate pre-modified with a monolayer of 4-mercaptopyridine (PySH) or 1,4-bis[2-(4-pyridyl)ethenyl]-benzene (BPENB) was studied by ultraviolet-visible (UV-Vis) and surface enhanced Raman scattering (SERS) spectroscopy. PySH or BPENB was used as a ligand to link RuPc since they not only modify the silver substrate, but also deliver a pyridyl group pointing out from the silver surface. Therefore, we can explore the relationship between the structure and orientation of metallophthalocyanine and the substrate modified by the two kinds of organic-monolayers with the different conjugates and molecular lengths. UV-Vis bands due to the organic-monolayer (PySH or BPENB) modified silver films shift to longer wavelengths and a new band arising from the metallophthlocyanine appears, suggesting the binding of RuPc to PySH/BPENB, as well as the interaction between the marcocycle of RuPc and the ring of PySH/BPENB. Vibrational bands arising from both the RuPc and PySH/BPENB moieties appear clearly in the SERS spectra of the RuPc-PySH/BPENB composite films, indicating that RuPc is successfully assembled on the top of PySH/BPENB film. The shifts and relative intensity changes of bands due to PySH or BPENB in the SERS spectra imply the binding of the metallophthalocyanine to the pyridyl group in the composite films. Furthermore, the comparison of the SERS spectra revealed that the orientations of PySH and BPENB in the two kinds of composite films are different; the BPENB moiety in the RuPc-BPENB composite film is more perpendicular to the silver surface compared with the PySH moiety in the RuPc-PySH composite film.

串级控制与Smith预估器结构融合

对串级控制系统来说,一个快速内回路是至关重要的.当副回路存在较大纯滞后时,系统控制品质会很差.Smith预估器是用于解决大纯滞后对象的有效方法.本文提出了串级控制与Smith预估补偿相结合的控制策略.针对纯滞后问题,讨论了串级控制与Smith补偿的互补性.从理论和仿真两个方面讨论了这种系统相结合的可行性和应用价值.仿真结果的表明,这种控制系统抗二次干扰的能力大大提高,其鲁棒稳定性和动态品质均优于单纯的Smith预估补偿控制和单纯的串级控制.

CS双醛淀粉希夫碱的制备及其对苯酚的吸附性能研究

以CS(壳聚糖)和双醛淀粉为反应原料,制备了吸附苯酚用CS双醛淀粉希夫碱。着重探讨了合成希夫碱的影响因素、希夫碱对苯酚的吸附动力学过程。研究结果表明:当n(CS)∶n(双醛淀粉)=2∶3、反应温度为70℃和反应时间为12 h时,制得的希夫碱具有相对最大的接枝率(65.4%);希夫碱对苯酚的吸附速率随吸附时间延长而逐渐下降,80 min时达到饱和吸附;当吸附质浓度为20 mg/L、吸附剂浓度为500 mg/L和吸附剂为0.05 g时,饱和吸附量为32.015 mg/g;拟1级、拟2级吸附动力学方程均具有良好的线性相关性,并且前者的拟合效果相对更好。
