带有模糊集值映象的一般混合拟变分包含的扰动近似点算法 总被引:5,自引:0,他引:5
本文引入一类新的带有模糊集值映象的一般混合拟变分包.在Hilbert空间中,利用极大η-单调映象的预解算子技巧,建立了这类变分包与不动点的等价性.利用这种等价性,构造了一些新的扰动近似点算法,并证明了由此算法所产生的迭代序列的收敛性.这些定理改进,统一和推广了近期文献中许多重要结果. 相似文献

An experimental study of the influence of external magnetic field on the fluidization behavior of magnetic pearls was carried out. Magnetic pearls are a magnetic form of iron oxide that mainly consists of Fe2O3 which are recovered from a high-volume power plant fly ash from pulverized coal combustion. Due to its abundance, low price and particular physical and chemical properties, magnetic pearls can be used as a heavy medium for minerals or solid waste dry separation based on density difference. This paper introduces the properties of magnetic pearls and compares the performance of magnetic pearls fluidised bed operation with or without an external magnetic field. Experimental results show that an external magnetic field significantly improves the fluidization performance of magnetic pearls such as uniformity and stability. 相似文献

CeO 2 nanocrystals with different morphologies were synthesized by adjusting the pH value of the starting solution in water-in-oil microemulsion.The obtained samples were characterized by transmission electron microscopy (TEM),X-ray diffraction (XRD),thermogravimetric analysis and different thermal analysis (TGA/DTA),Brunauer-Emmet-Teller (BET) surface area measurement,ultraviolet-visible absorption (UV-vis) spectroscopy and photoluminescence (PL) spectroscopy.Results show that the morphologies of CeO 2 wer... 相似文献
