During the manufacturing process of dielectric materials used in electromagnetic engineering, the electromagnetic parameters are often spatially uncertain due to the processing technology, environmental temperature, personal operations, etc. Traditionally,the random field model can be used to measure the spatial uncertainties, but its construction requires a large number of *** the contrary, the interval field model only needs the upper and lower bounds of the spatially uncertain parameters, which requires much less samples and furthermore is easy to understand and use for engineers. Therefore, in this paper, the interval field model is introduced to describe the spatial uncertainties of dielectric materials, and then an interval finite element method(IFEM) is proposed to calculate the upper and lower bounds of electromagnetic responses. Firstly, the interval field of the dielectric material is represented by the interval K-L expansion and inserted into the scalar Helmholtz wave equations, and thus the interval equilibrium equations are constructed according to the node-based finite element method. Secondly, a perturbation interval finite element method is developed for calculating the upper and lower bounds of electromagnetic responses such as the electric strength and magnetic strength. Finally, the effectiveness of the proposed method is verified by three numerical examples.

克尔凯郭尔与卢卡奇马克思主义哲学观的流变

克尔凯郭尔并非卢卡奇偶然提及的学术注脚,而是其理解马克思的背景支援。卢卡奇在不同时期都对克尔凯郭尔作了选择性评述,并将其接受或重构马克思主义哲学的曲折心路历程逐一呈现:通过质疑克尔凯郭尔在人与世界相统一问题上遭遇的“审美—伦理”悖论,青年卢卡奇从心灵掘进到阶级意识,将“主体—总体”辩证图式看作马克思的认识论地平,由此创作出《历史与阶级意识》;之后,为回应该书引起的争议,盛年的卢卡奇以批判克尔凯郭尔的非理性主义为契机,尝试清除“主体—总体”辩证图式中残余的主体形而上学痕迹,开始在方法论维度正视生产实践与经济规律间的有机联系;及至晚年,当卢卡奇立足社会存在,抨击克尔凯郭尔有关主体优先性的宗教幻象时,他又把社会性的“自在—自为”运动内嵌于人性的“主体—总体”辩证图式,并根据超然的悟性,默认马克思主义哲学是将经济规律置于从属地位的劳动本体论,再度退回《历史与阶级意识》的主体形而上学谋划。不难看出,在卢卡奇臧否克尔凯郭尔与马克思的“主体—总体”辩证桥段中,当事人对“人之实然性和应然性的现实统一”问题所秉持的龃龉心态暴露无遗。这也恰好说明,卢卡奇一生都徘徊于正统的马克思主义与人道的马克思主义之间。

We study the spatiotemporal Bloch states of a high-frequency driven two-component Bose–Einstein condensate(BEC)with spin–orbit coupling(SOC) in an optical lattice. By adopting the rotating-wave approximation(RWA) and applying an exact trial-solution to the corresponding quasistationary system, we establish a different method for tuning SOC via external field such that the existence conditions of the exact particular solutions are fitted. Several novel features related to the exact states are demonstrated; for example, SOC leads to spin–motion entanglement for the spatiotemporal Bloch states, SOC increases the population imbalance of the two-component BEC, and SOC can be applied to manipulate the stable atomic flow which is conducive to control quantum transport of the BEC for different application purposes.
