In blasting engineering, the location and number of detonation points, to a certain degree, regulate the propagation direction ofthe explosion stress wave and blasting effect. Herein, we examine the explosion wave field and rock breaking effect in terms of shockwave collision, stress change of the blast hole wall in the collision zone, and crack propagation in the collision zone. The produced shockwave on the collision surface has an intensity surpassing the sum of the intensities of the two colliding explosion shock waves. At the collisionlocation, the kinetic energy is transformed into potential energy with a reduction in particle velocity at the wave front and the wavefront pressure increases. The expansion form of the superposed shock wave is dumbbell-shaped, the shock wave velocity in the collisionarea is greater than the radial shock wave velocity, and the average propagation angle of the explosion shock waves is approximately 60°.Accordingly, a fitted relationship between blast hole wall stress and explosion wave propagation angle in the superposition area is *** the experimental conditions, the superimposed explosion wave stress of the blast hole wall is approximately 1.73 times the singleexplosionwave incident stress. The results of the model test and numerical simulations reveal that large-scale radial fracture cracks weregenerated on the blast hole wall in the superimposed area, and the width of the crack increased. The width of the large-scale radial fracturecracks formed by a strong impact is approximately 5% of the blast hole length. According to the characteristics of blast hole wallcompression, the mean peak pressures of the strongly superimposed area are approximately 1.48 and 1.84 times those of the weakly superimposedand nonsuperimposed areas, respectively.

Optoelectronics Letters 2024年

作者： LIU Zijian SONG Jian CHEN quanmin XU Jiangtao Tianjin Key Laboratory of Imaging and Sensing Microelectronic Technology， School of Microelectronics， Tianjin University Spikesee Technology Co.， Ltd.

Although guided image filtering (GIF) is known for preserving edges and fast computation， it may produce inaccurate outputs in depth map restoration. In this paper， a novel confidence-weighted GIF called mutual-structure weighted GIF (MSWGIF) is proposed， which replaces the mean filtering strategy in GIF during handling overlapping windows. The confidence value is composed of a depth term and a mutual-structure term， where the depth term is utilized to protect the edges of the output， and the mutual-structure term helps to select accurate windows during the structure characteristics of the guidance image are transferred to the output. Experimental results show that MSWGIF reduces the root mean square error by an average of 12.37%， and the average growth rate of correlation is 0.07% on average. Additionally， the average growth rate of structure similarity index measure is 0.34%.

近年来,在机器学习和数据技术的强力推进下,计算哲学正在蓬勃地发展,它是运用计算的思想、方法和工具研究哲学问题的新进路,而不是一个哲学的新分支或新学科。就基本目标而言,计算哲学与分析哲学之间并没有实质性的不同,但在背景知识、面向问题和研究方法上存在不少重要的差别。因此,前者应该被看作当代分析哲学发展的新阶段或新拓展。随着人工智能的突破性发展,在不久的将来,很可能出现一个人工智能驱动的哲学研究新方向,这预示着一个哲学的计算时代的到来。

红外探测与遥感是气象观测的核心技术,红外辐射探测仪作为气象卫星的重要载荷,主要用于大气温度、湿度的定量化探测,其探测精度取决于光谱和偏振测量的通道数。常见的技术方案是通过组合滤光片与偏振片转轮实现光谱和偏振的探测,这造成了系统体积大、功耗高、通道数少的问题。发展片上集成式偏振光谱成像器件是解决上述问题的有效方法,已有研究主要采用薄膜谐振腔或共振微结构的阵列化方案,但二者都无法兼顾光谱和偏振选择的要求。有鉴于此,提出了一种基于薄膜微结构耦合调控的设计新思路,以13μm附近的大气红外波段为例,实现了片上集成式的偏振光谱成像,6个通道的平均透过率和消光比分别达到了94%和30。该器件有望在将来被广泛应用于偏振光谱成像领域中,同时,由于该器件对基底折射率并不敏感,基底的选择也会更加自由。
