Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT A major challenge in fabricating eutectic NiTiNb alloys is the incomplete melting of Nb due to its much higher melting point than the NiTi matrix. In this work, a novel electron‐beam freeform additive manufacturing strategy is developed to eliminate unmelted Nb particles and achieve a fully eutectic structure through independent dual‐wire ...

Effects of the distribution of vegetation on small catchment runoff during rainstorm events
, 2015 基于二维运动波模型,建立了一个适用于小流域场次降雨产汇流过程的动力学模型。通过对典型小流域内不同区域(坡顶、坡中及坡底区域及距离流域出口的远近)种植植被时产流过程的数值模拟,分析了小流域内植被分布对产流过程的影响。结果表明:植被分布及其特性对小流域场次降雨产流有较明显的影响;下游区域种植植被的减水效果和延滞洪峰作用优于上游区域,陡坡区域减水效果优于缓坡区域,且郁闭度越大,这种差别越明显;在该研究条件下,下游区的减水效果可达到上游区的3倍;30%郁闭度条件下减水效果可达10%和20%郁闭度条件下的3倍和1.

International Journal of Applied Linguistics, Volume 36, Issue 1, Page 714-724, February 2026.ABSTRACT Interlingual translation, as defined by Roman Jakobson, refers to the transfer of meaning between languages. However, this concept has often been conflated with linguistic shifts between distinct cultures and nation‐states. To challenge this misconception, I propose the concept of self‐consumption translation (SCT), a subfield of interlingual ...

Shuitu Baochi Xuebao, 1996 运用人工模拟降雨研究了裸地及不同盖度沙打旺草地产流产沙过程。结果表明：裸地产流产沙过程可用指数函数ｙ＝ｅａ＋ｂｘ型式描述；不同盖度的沙打旺草地产流产沙过程均可用幂函数ｙ＝ａｘｂ来描述，且随着盖度由大向小变化，方程参数ａ值减小，ｂ值增大。

Shuitu Baochi Xuebao, 2020 准确地预测农田地表径流是实现农业面源污染控制的基础，根据降雨和地表径流的运动特征，耦合Green-Ampt模型累积入渗量显函数、运动波模型和稳态的产沙模型，建立了降雨条件下的坡面产流产沙近似解析模型。该模型通过线性表示入渗率和水深之间的关系近似求解了运动波方程，通过设置30~90 mm/h的5种不同雨强的模拟降雨试验，推求模型参数并验证模型精度，并对模型参数进行敏感性分析。结果表明：（1）径流和泥沙的模型计算值与实测值吻合较好，且模型更适合于模拟60 mm/h雨强下的产流产沙过程，曼宁糙率系数均分布在0.

Shuitu Baochi Xuebao, 2022 设置不同PAM施加量(0,0.4,0.8,1.6 g/m2),在不同坡度(15°,20°,25°)条件下开展不同雨强(60,90,120 mm/h)的模拟降雨试验。研究不同PAM施加量紫色土坡面片蚀产流产沙过程及其对产流产沙量的影响程度和主要因素,并分析了PAM对坡面片蚀可蚀性的影响。结果表明:坡面产流过程呈现先持续增加后趋于波动稳定的变化趋势,产沙过程则呈现先迅速减少并趋于稳定的变化趋势,PAM对片蚀的产流产沙过程变化趋势没有影响。和空白对照组相比,PAM施加量为0.4,0.8,1.6 g ...

Modelling soil erosion in a small catchment on the Chinese Loess Plateau : Applying LISEM to extreme conditions [PDF]
, 2002 The Chinese Loess Plateau suffers some of the highest soil erosion rates on earth. This is caused by the fact that it can be characterized as a semi-arid area with low vegetation cover, erodible soils, steep slopes and occasional high intensity summer ...
