The application of an external field is a promising method to control the microstructure of materials, leading to their improved per-formance. In the present paper, the strengthening and toughening behavior of some typical high-performance structural materials subjected to multifield coupling treatment, including electrostatic field, electro-pulse current, thermal field, and stress field, are reviewed in detail. In addi-tion to the general observation that the plasticity of materials could be increased by multi-external fields, strength enhancement can be achieved by controlling atomic diffusion or phase transformations. The paper is not limited to the strengthening and toughening mechanisms of the mul-tifield coupling effects on different types of structural materials but is intended to provide a generic method to improve both the strength and ductility of the materials. Finally, the prospects of the applications of multi-external fields have also been proposed based on current works.

针对轮换迭代算法在混合互耦误差和幅相误差条件下存在估计精度不高的问题,提出了一种改进非迭代多重信号分类(improved non-iterative multiple signal classification,INI-MUSIC)算法.改进算法利用误差系数在均匀圆阵下的特殊性质和矩阵向量转换定理,将幅相误差和互耦误差与波达方向(direction of arrival,DOA)估计角度分离,从而实现混合误差下的降维操作,进而通过重新构造代价谱峰函数对亏损的秩进行补偿,实现对DOA角度的估计和对误差系数的
大跨度高速铁路桥常采用刚度和动力性能良好的拱桥结构,但是随着拱桥服役期增长,列车运营速度不断提高,结构性能退化严重,难以满足正常运营的要求.为了解决现役铁路拱桥存在力学性能不足的问题,基于三角形稳定性和桁架结构变形小的原理,提出一种结构改进方法,具体做法为在拱肋与主梁之间增设若干个V型结构,使其与拱和梁段构成若干个连续的三角形结构,从而对主梁与拱肋进行有效约束.V型结构布置的位置需综合考虑对拱肋与主梁的均匀约束及其结构的薄弱位置,其个数尽可能使结构的刚度与温度响应之间达到较为合理的平衡状态.有限元分析结果
Mo薄膜是CIGS薄膜太阳电池背电极的首选材料,对薄膜与基底间的结合力提出很大要求.为提高Mo薄膜与基底结合力,借助L9(33)正交表研究基底温度、溅射气压和溅射功率3种影响因素对Mo薄膜结合力的影响,针对每种因素各选取3个水平值.采用压入法衡量薄膜与基底的结合力,结合力的评价指标为压入引起的裂纹的面积,利用改进版龟裂评级法得出裂纹面积.通过极差分析得到基底温度、溅射气压、溅射功率所对应的R值分别为6.51、18.29、5.96;最优水平组合为A1 B2 C3,此时裂纹面积最小,为2.41μm2.结果表明
