Unsubmerged cavitating abrasive waterjet(UCAWJ) has been shown to artificially create a submerged environment that produces shear cavitation, which effectively enhances rock-breaking performance. The shear cavitation generation and collapse intensity depend on the pressure difference between the intermediate high-speed abrasive waterjet and the coaxial low-speed waterjet. However, the effect of the pressure of the coaxial low-speed waterjet is pending. For this purpose, the effect of low-speed waterjet pressure on rock-breaking performance at different standoff distances was experimentally investigated,and the effects of erosion time and ruby nozzle diameter on erosion performance were discussed. Finally,the micromorphology of the sandstone was observed at different locations. The results show that increased erosion time and ruby nozzle diameter can significantly improve the rock-breaking performance. At different standoff distances, the mass loss increases first and then decreases with the increase of low-speed waterjet pressure, the maximum mass loss is 10.4 g at a low-speed waterjet pressure of0.09 MPa. The surface morphology of cavitation erosion was measured using a 3D profiler, the increase in both erosion depth and surface roughness indicated a significant increase in the intensity of the shear cavitation collapse. At a low-speed waterjet pressure of 0.18 MPa, the cavitation erosion surface depth can reach 600 μm with a roughness of 127 μm.

Readout errors caused by measurement noise are a significant source of errors in quantum circuits,which severely affect the output results and are an urgent problem to be solved in noisy-intermediate scale quantum(NISQ)*** this paper,we use the bit-flip averaging(BFA)method to mitigate frequent readout errors in quantum generative adversarial networks(QGAN)for image generation,which simplifies the response matrix structure by averaging the qubits for each random bit-flip in advance,successfully solving problems with high cost of measurement for traditional error mitigation *** experiments were simulated in Qiskit using the handwritten digit image recognition dataset under the BFA-based method,the Kullback-Leibler(KL)divergence of the generated images converges to 0.04,0.05,and 0.1 for readout error probabilities of p=0.01,p=0.05,and p=0.1,***,by evaluating the fidelity of the quantum states representing the images,we observe average fidelity values of 0.97,0.96,and 0.95 for the three readout error probabilities,*** results demonstrate the robustness of the model in mitigating readout errors and provide a highly fault tolerant mechanism for image generation models.

堆肥中溶解性有机质(DOM)对重金属具有显著的络合作用,影响其在环境中的迁移和转化。研究采用三维荧光-平行因子(EEM-PARAFAC)结合二维相关光谱(2DCOS)分析方法,系统解析蘑菇渣堆肥(MRC)及水稻秸秆堆肥(RSC)中DOM与Cu^(2+)的络合机制。EEM-PARAFAC结果表明,MRC-DOM和RSC-DOM主要由类腐殖酸(C1)、类富里酸(C2)和类蛋白质(C3)组成,各组分分别占MRC-DOM总荧光强度的43%、32%和25%,占RSC-DOM的39%、29%和32%。2种堆肥DOM与Cu^(2+)作用过程中,3类组分荧光强度均呈不断降低趋势,表明它们均与Cu^(2+)发生了显著的络合作用。2种堆肥中不同荧光组分(C1~C3)与Cu^(2+)的有效猝灭常数(lg K)在4.54~4.76之间,均表现为C3>C1>C2,表明类蛋白组分(C3)与Cu^(2+)结合能力最强,其次为类腐殖酸(C1),类富里酸(C2)最低。2DCOS结果显示,堆肥DOM中类蛋白荧光组分与Cu^(2+)结合能力最强,而类富里酸优先与Cu^(2+)发生反应。总体而言,MRC-DOM和RSC-DOM中类蛋白和类腐殖质组分是与Cu^(2+)发生络合作用的关键物质,且2类堆肥DOM具有类似的Cu^(2+)络合机制(包括活性位点、络合能力和反应顺序)。研究结果为进一步了解堆肥对土壤Cu^(2+)迁移和转化行为的影响提供了重要的理论基础。
