The high energy coordination compounds Cu(TZCA)_(2)(ClO_(4))_(2)(ECCs-1) was prepared by 1H-tetrazole-5-carbohydrazide(TZCA) with a high energy skeleton and a strong coordination ability group.At the same time,the reaction activity of the ligand was explored,and the single crystal structure of it and intermediate were obtained.The structures of all substances were characterized by IR and EA.And the structure and composition of ECCs-1 are confirmed by ESP,AC,SEM and ICP-OES.Physical and chemical properties tests show that ECCs-1 has an acceptable thermal stability(T_(d)=177℃) and extremely sensitive mechanical stimulation(IS=1 J,FS=5 N).The comprehensive performance test results show that ECCs-1 has excellent initiation ability.In addition,the decomposition mechanism of ECCs-1 is explored from two aspects of experiment and theoretical calculation.

随着隧道滑坡体系支护研究的深入,隧道滑坡与抗滑桩支护之间的受力研究尤为重要。为研究在0°、10°、20°、30°、40°、50°共6种滑带角度影响下隧道衬砌结构与抗滑桩的受力特征,以大准铁路南坪隧道为原型,采取室内缩尺试验以及数值模拟的方法,对三者间受力变形规律进行研究。得到以下结论:随着滑带角度的增大,桩身与隧道衬砌结构变形逐渐减小,作用在隧道以及桩身的土压力、弯矩值逐渐减小;同时,滑带角度为0°、10°、20°、30°时滑坡水平推力对隧道衬砌结构受力影响较大,40°、50°时滑坡水平推力影响显著衰减,拱脚竖向荷载占比逐渐增大。当滑带角度小于30°时,应当主要考虑滑坡水平推力对隧道结构的影响,大于30°时主要考虑由滑坡体所产生的竖向荷载对隧道衬砌结构的影响,此时应当对隧道仰拱及靠近坡体处拱脚位置重点加固。所得试验、模拟结果为隧道与抗滑桩体支护施工提供一定参考。

This paper investigates the problem of Spacecraft Formation-Containment Flying Control(SFCFC)when the desired translational velocity is time-varying.In SFCFC problem,there are multiple leader spacecraft and multiple follower spacecraft and SFCFC can be divided into leader spacecraft’s formation control and follower spacecraft’s containment control.First,under the condition that only a part of leader spacecraft can have access to the desired time-varying translational velocity,a velocity estimator is designed for each leader spacecraft.Secondly,based on the estimated translational velocity,a distributed formation control algorithm is designed for leader spacecraft to achieve the desired formation and move with the desired translational velocity simultaneously.Then,to ensure all follower spacecraft converge to the convex hull formed by the leader spacecraft,a distributed containment control algorithm is designed for follower spacecraft.Moreover,to reduce the dependence of the designed control algorithms on the graph information and increase system robustness,the control gains are changing adaptively and the parametric uncertainties are handled,respectively.Finally,simulation results are provided to illustrate the effectiveness of the theoretical results.

A new robust electronic image stabilization system is presented, which involves feature-point, tracking based global motion estimation and Kalman filtering based motion compensation. First, global motion is estimated from the local motions of selected feature points. Considering the local moving objects or the inevitable mismatch, the matching validation, based on the stable relative distance between the points set is proposed, thus maintaining high accuracy and robustness. Next, the global motion parameters are accumulated for correction by Kalman filteration. The experimental result illustrates that the proposed system is effective to stabilize translational, rotational, and zooming jitter and robust to local motions.

Developing novel magnetocaloric materials is of great significance for the applications of magnetic refrigeration.In this study,we designed a heterogeneous rare-earth-based high-entropy alloy(HEA)comprising amorphous matrix,local crystal-like cluster and nanocrystalline dihydride with average size of 7.5 nm through isothermal hydrogenation.This heterogeneous structure can significantly tune the magnetocaloric effect of alloy.After hydrogenation,the predominant exchange interaction transforms from ferromagnetic to antiferromagnetic with the disappearance of spin-glass-like behavior,and a complete second-order magnetic transition is obtained.Compared with the Gd_(20)Tb_(18)Dy_(18)Co_(20)Al_(24) high-entropy metallic glass with a small number of nanocrystals,the maximum magnetic entropy change of the hydrogen-containing HEA is increased from 8.8 to 13.6 J kg^(-1)K^(-1) under applied magnetic field change of 5 T accompanying unobvious hysteresis and decreased magnetic transition temperature from 59 to 8 K,which is more promising as magnetic refrigerant at cryogenic temperature.This work provides a novel concept of designing heterogeneous structure in terms of special cluster and preferential nanocrystalline to modulate the properties of metallic glasses.

Shape memory alloy metal rubber(SMAMR)is a novel intelligent elastic damping material which can realize the integration of structure and function.The investigations on the anisotropic mechanical characteristics which depended on shaping craft and working temperature were conducted by quasi-static tests.Comparative experiments indicated that the heat setting temperature affect the elastic modulus non-monotonously but has little effect on the loss factor of SMAMR in both martensite and austenite phases.With the increase of the heat setting time,the elastic modulus of SMAMR monotonously decreases and the reduction of loss factor is unobvious.With the present shaping craft,SMAMR exhibits the anisotropy in moulding and non-moulding directions,which is affected by the heat setting process and working temperature.It was proved that the mechanical properties have approximately linear relationship with temperature during the phase transition process.Due to its temperature-dependent mechanical properties,SMAMR that experiences the heat setting procedure is expected to be used in active vibration control systems with varying temperature-dependent stiffness and damping coefficients to provide superior vibration control performance.
