Background In the past decades, the one-year graft survival of cadaveric renal allografts has been markedly improved,but their long-term survival has not kept pace. The attrition rate of renal allografts surviving after one year remains almost unchanged. The causes for late graft loss are multiple. The aim of this study was to analyze the predictive factors that impact long-term survival of grafts after kidney *** We retrospectively analyzed 524 kidney transplantation patients who were treated in our hospital between January 1991 and January 2000, including 254 patients who had lived more than 10 years with normal graft function （long survival group）, and 270 cases whose renal graft had survived less than 10 years （control group）. Specifically, we analyzed 10 factors that may potentially affect graft survival by both univariate and Logistic model multivariate analyses to pinpoint the independent risk *** Univariate analyses showed that no significant differences existed in the age or gender of recipients, dialysis time, lymphotoxin levels, or cold ischemia time between the two groups. However, the ratio of delayed graft function and acute rejection, and the uric acid levels of patients in the long survival group were significantly lower than those in the control group （P ＜0.01）. Furthermore, we found that the concentration of cyclosporin A at one year after transplantation and the histocompatibility antigen match of donor-recipients for patients within the long survival group were significantly higher than those in the control group （P ＜0.01 ）. Furthermore, multivariate analyses showed that these four factors were independent risk factors that impact patient *** The ratios of delayed graft function and acute rejection, the concentration of cyclosporin A at one year after transplantation, and serum uric acid levels are very important factors that affect the long-term survival of renal grafts.

在低品位、多夹层盐矿地层中建设地下储库,利用水采溶腔(盐穴)底部不溶物沉渣空隙储气有望较大幅度扩大储气库库容,但需要开展沉渣空隙储气可行性和适用性评估。首先,采用不溶物沉渣制备大尺寸CT扫描试样,构建了沉渣空隙三维重构模型,定性分析了沉渣空隙尺寸和空隙连通性,发现沉渣空隙尺寸大且连通性好;其次,采用自主研制的盐矿水采沉渣储气试验装置,利用不溶物小颗粒和夹层垮塌大尺寸块体混合堆积样品进行注气排卤试验,测定注气排卤前后沉渣空隙率,分析了沉渣空隙率变化的原因;最后,建立沉渣空隙体积预测模型,提出了盐腔采动空间和沉渣可排卤水体积的计算公式。通过考虑盐层不溶物小颗粒连续堆积,又考虑夹层垮塌大尺寸块体无序堆积,计算了沉渣堆积体积及可排卤储气体积,计算结果与现场采卤数据吻合较好。该研究可为评价低品位、多夹层盐矿沉渣空隙储气能力提供参考。

Methane, an abundant one-carbon（C1） resource, is extensively used in the industrial production of vital fuels and value-added chemicals. However, current industrial methane conversion technologies are energy-and carbon-intensive, mainly due to the high activation energy required to break the inert C–H bond, low selectivity, and problematic side reactions, including CO2emissions and coke deposition. Electrochemical conversion of methane（ECM） using intermittent renewable energy offers an attractive solution, due to its modular reactor design and operational flexibility across a broad spectrum of temperatures and pressures. This review emphasizes conversion pathways of methane in various reaction systems, highlighting the significance and advantages of ECM in facilitating a sustainable artificial carbon cycle. This work provides a comprehensive overview of conventional methane activation mechanisms and delineates the complete pathways of methane conversion in electrolysis contexts. Based on surface/interface chemistry, this work systematically analyzes proposed reaction pathways and corresponding strategies to enhance ECM efficiency towards various target products, including syngas, hydrocarbons, oxygenates, and advanced carbon materials. The discussion also encompasses opportunities and challenges for the ECM process, including insights into ECM pathways, rational electrocatalyst design, establishment of benchmarking protocols, electrolyte engineering, enhancement of CH4conversion rates, and minimization of CO2emission.

为了更简便地从滑动轴承非线性油膜力直接识别获得油膜动力特性系数,从频域角度建立了轴颈在轴承中的扰动与非线性油膜力之间的关系,采用等幅异频位移激励技术,一次性识别出油膜8个刚度和阻尼特性系数,通过圆瓦滑动轴承实例验证了该方法的准确性,分析了扰动幅值和频率对识别精度的影响。研究结果表明,扰动频率对识别精度没有明显影响,而扰动幅值对识别精度有较大影响,当扰动幅值大于0.016倍半径间隙时,识别精度超过5%。当扰动幅值小于0.005倍半径间隙时,识别精度在0.5%以内,0.001倍半径间隙时,所给出的油膜动力特性系数识别方法的识别精度可达到0.045%。
