【目的】分析贸易争端对中国玉米生产和消费的影响,从而找到提升玉米竞争力的主要途径。【方法】采取定量分析与定性分析相结合和比较分析等方法,对中国玉米的贸易现状进行了分析,在此基础上,以生产玉米量较大的美国作为分析对象,通过对中美两国玉米的生产量、生产成本、生产价格及消费量进行了比较分析。【结果】中美贸易争端对中国玉米生产和消费的影响较大,具体表现为中美贸易争端直接导致中国进口美国玉米量大幅下跌;面对巨大的国内市场需求,玉米的市场供给量减少,供需矛盾逐年加剧,玉米的价格不断攀升;农民加大投入导致生产成本不断上涨,生产量也逐渐提高。【结论】中美贸易争端对中国玉米市场的影响较为明显,说明中国玉米进口依赖性较大,参与国际竞争力明显不足。国家应该采取拓展进口市场和渠道,实施进口市场多元化。加大科技投入,实现玉米生产方式的转变。降低玉米生产成本,调整玉米种植结构。加大玉米补贴力度,实现补贴形式多样化等系列措施,切实提高玉米的竞争力,减少对国际玉米市场的依赖性。

For the purpose of investigating the influence of metastable olivine（MO） phase transformations on both deep seismicity and stagnation of slabs,we constructed a 2-dimensional finite element thermal model for a 120 Ma-old 50°dipping oceanic lithosphere descending at 10 cm/yr with velocity boundary layers,which would mitigate the interference of constant velocity field for the slab. The resulting temperatures show that most of intermediate and deep earthquakes occurring within the Tonga slab are occurring inside the 800℃and 1200℃isotherm,*** elevation of olivine transformation near～410 km and respective persistence of metastable olivine and spinel within the transition zone and beneath 660 km would thus result in bimodal positive,zonal,negative density anomalies,*** results together with the resulting pressure anomalies may reflect the stress pattern of the Tonga slab：（i） slab pull force exerts above a depth of～230 km;（ii） MO existence changes the buoyancy force within the transition zone and facilitates slab stagnation at a depth of 660 km;（iii） as the subducting materials accumulated over 660 km,deepest earthquakes occur due to MO transformation;（iv） a flattened‘slab’ may penetrate into the lower mantle due to the density increment of Sp transformation.

目的探讨椎-基底动脉迂曲与老年血管源性头晕/眩晕脑梗死的关系。方法选取2022年1月至2023年10月太原西山医院神经内科住院的老年血管源性头晕/眩晕脑梗死患者160例,根据头颅磁共振血管成像检查是否存在椎-基底动脉异常将其分为迂曲组和非迂曲组,每组各80例。比较两组患者的一般临床资料、血管病危险因素、美国国立卫生研究院卒中量表扩展版(expanded-National Institutes of Health stroke scale,e-NIHSS)评分。迂曲组根据椎-基底动脉形态又分为单纯异常组和混合异常组,分析对相关脑梗死的影响程度。结果迂曲组患者的高血压、椎动脉优势、吸烟史的比例和e-NIHSS评分均显著高于非迂曲组(P<0.05)。多因素Logistic回归分析结果显示,高血压病史、椎动脉优势、吸烟史均是伴有椎-基底动脉异常老年血管源性头晕/眩晕脑梗死患者的独立危险因素(P<0.05)。单纯异常组中54.3%为中重度脑卒中患者,混合异常组中58.8%为中重度脑卒中患者,两组比较差异无统计学意义(χ^(2)=0.029,P=0.864)。结论高血压病史、椎动脉优势、吸烟史是伴有椎-基底动脉迂曲的老年血管源性头晕/眩晕脑梗死的独立危险因素,此类患者神经功能缺损评分更高。

Non-negative Tucker decomposition(NTD) has been developed as a crucial method for non-negative tensor data ***, NTD is essentially an unsupervised method and cannot take advantage of label information. In this paper, we claim that the low-dimensional representation extracted by NTD can be treated as the predicted soft-clustering coefficient matrix and can therefore be learned jointly with label propagation in a unified framework. The proposed method can extract the physicallymeaningful and parts-based representation of tensor data in their natural form while fully exploring the potential ability of the given labels with a nearest neighbors graph. In addition, an efficient accelerated proximal gradient(APG) algorithm is developed to solve the optimization problem. Finally, the experimental results on five benchmark image data sets for semi-supervised clustering and classification tasks demonstrate the superiority of this method over state-of-the-art methods.
