In this paper, we introduce the concept of second-order compound contingent epiderivative for set-valued maps and discuss its relationship to the second-order contingent epiderivative. Simultaneously, we also investigate some special properties of the second-order compound contingent epiderivative. By virtue of the second-order compound contingent epiderivative, we establish some unified second-order sufficient and necessary optimality conditions for set-valued optimization problems. All results in this paper generalize the corresponding results in the literature.

This paper proposes a finite-time robust flight controller, targeting for a reentry vehicle with blended aerodynamic surfaces and a reaction control system（RCS）. Firstly, a novel finite-time attitude controller is pointed out with the introduction of a nonsingular finite-time sliding mode manifold. The attitude tracking errors are mathematically proved to converge to zero within finite time which can be estimated. In order to improve the performance, a second-order finite-time sliding mode controller is further developed to effectively alleviate chattering without any deterioration of robustness and accuracy. Moreover, an optimization control allocation algorithm, using linear programming and a pulse-width pulse-frequency（PWPF） modulator, is designed to allocate torque commands for all the aerodynamic surface deflections and on–off switching-states of RCS *** are provided for the reentry vehicle considering uncertain parameters and external disturbances for practical purposes, and the results demonstrate the effectiveness and robustness of the attitude control system.

采用基于密度泛函理论的第一性原理,计算了本征CsPbI_(3)和Mn、Zn、Sn掺杂体系的形成能、电子结构和光学性质.研究结果表明:Mn、Zn、Sn的掺入减小了材料晶格常数,Mn原子掺入CsPbI_(3)晶体结构使得体系的磁矩由0变为5.00μ_(B),丰富了材料磁性.与Zn掺杂体系相比,Mn、Sn掺杂体系更为稳定.Mn掺杂体系增大了材料带隙,Zn、Sn的掺入使材料带隙分别减小了30.2%和16.2%,有利于电子极化跃迁,但Zn掺入使CsPbI_(3)材料转变为间接带隙半导体.在可见光区域中Mn、Zn、Sn掺杂体均表现出优异的光学性能,Sn掺杂体系效果最佳.这些研究结果为实验方面CsPbI_(3)材料的掺杂改性提供了数据支持,有利于CsPbI_(3)钙钛矿在光电领域的应用.

In this paper, minimax theorems and saddle points for a class of vector-valued mappings f（x, y） = u（x）＋ β（x）v（y） are first investigated in the sense of lexicographic order, where u, v are two general vector-valued mappings and β is a non-negative real-valued function. Then, by applying the existence theorem of lexicographic saddle point, we investigate a lexicographic equilibrium problem and establish an equivalent relationship between the lexicographic saddle point theorem and existence theorem of a lexicographic equilibrium problem for vector-valued mappings.
