Outwash deposit is a unique type of geological materials, and its features such as heterogeneity, discontinuity and nonlinearity determine the complexity of mechanical characteristics and failure mechanism. In this work, random meso-structure of outwash deposits was constructed by the technique of computer random simulation based on characteristics of its meso-structure in the statistical sense and some simplifications, and a series of large direct shear tests on numerical samples of outwash deposits with stone contents of 15%, 30%, 45% and 60% were conducted using the discrete element method to further investigate its mechanical characteristics and failure mechanism under external load. The results show that the deformation characteristics and shear strength of outwash deposits are to some extent improved with the increase of stone content, and the shear stress–shear displacement curves of outwash deposits show great differences at the post-peak stage due to the random spatial distribution and content of stones. From the mesoscopic view, normal directions of contacts between "soil" and "stone" particles undergo apparent deflection as the shear displacement continues during the shearing process, accompanying redistribution of the magnitude of contact forces during the shearing process. For outwash deposits, the shear zone formed after shear failure is an irregular stripe due to the movements of stones near the shear zone, and it expands gradually with the increase of stone content. In addition, there is an approximately linear relation between the mean increment of internal friction angle and the stone content lying between 30% and 60%, and a concave nonlinear relation between the mean increment of cohesion and stone content, which are in good agreement with the existing research results.

We have developed a type of L-shaped single-component geophone array as a single station(L-array station)for surface microseismic *** L-array station consists of two orthogonal sensor arrays,each being a linear array of single-component sensors.L-array stations can be used to accurately estimate the polarization of first arrivals without amplitude *** a synthetic example,we first use segmentally iterative ray tracing(SIRT)method and forward model to calculate the travel time and polarization of first arrivals at a set of L-array ***,for each L-array station,the relative delay times of first arrivals along sensor arrays are used to estimate the polarization *** small errors in estimated polarization vectors show the reliability and robustness of polarization estimation based on L-array *** then use reverse-time ray-tracing(RTRT)method to locate the source position based on estimated polarizations at a set of L-array *** small errors in inverted source location and origin time indicate the great potential of L-array stations for source localization applications in surface microseismic monitoring.

目的检测特发性膜性肾病(idiopathic membranous nephropathy,IMN)患者血脂水平,分析其与抗磷脂酶A2受体(phospholipase A2 receptor,PLA2R)抗体和病理学表现的相关性及预后价值。方法选取2020年4月至2023年4月平顶山市第一人民医院诊治的IMN患者124例,收集临床和病理资料。Spearman检验和logistic回归分析血脂水平和临床病理特征的关系,Cox回归评估血脂水平对治疗后蛋白尿缓解的预测能力。结果高密度脂蛋白胆固醇(HDL-C)降低和甘油三酯(TG)升高与肾小管萎缩相关,非高密度脂蛋白胆固醇(non-HDL-C)和TG降低与补体C1q沉积相关。TC(r=0.432,P<0.001)、non-HDL-C(r=0.462,P<0.001)、低密度脂蛋白胆固醇(LDL-C)(r=0.315,P<0.001)和TG(r=0.289,P<0.001)与蛋白尿正相关,HDL-C(r=-0.099,P=0.039)与蛋白尿负相关。TC(r=0.323,P<0.001)、non-HDL-C(r=0.396,P<0.001)和LDL-C(r=0.401,P<0.001)与血清抗PLA2R抗体滴度正相关,HDL-C(r=-0.057,P=0.539)和TG(r=0.110,P=0.229)与血清抗PLA2R抗体滴度无显著相关性。血清抗PLA2R抗体滴度(r=0.502,P<0.001)和肾小球LA2R沉积(r=6.381,P<0.001)与蛋白尿正相关。结论血脂异常与IMN患者病理表现存在相关性,高胆固醇血症是肾小球PLA2R沉积和血清抗PLA2R抗体阳性的独立危险因素,HDL-C、non-HDL-C和LDL-C是治疗后蛋白尿缓解的预测因素。
