Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Nickel‐based superalloys (Ni‐based superalloys) have attracted extensive attention in laser additive manufacturing (LAM) due to their capability to directly fabricate complex and high‐performance structural components. However, the rapid melting and solidification inherent to LAM result in intense thermal cycling, which induces high residual ...

贵州省黔南区不同侵蚀性雨型条件下生物措施对坡面产流产沙的响应
Shuitu Baochi Xuebao, 2020 为探讨不同降雨条件下的生物措施对坡面产流产沙特征的影响，分析了贵州省黔南自治州云雾水土保持监测站2014—2017年4年6个小区104次侵蚀性降雨下的实测产流产沙数据。结果表明：（1）侵蚀性降雨按历时、雨强和雨量可分为3类，包括A雨型（中历时、中雨强、中雨量），B雨型（长历时、小雨强、大雨量），C雨型（短历时、大雨强、小雨量）。C雨型为引起区域水土流失的主要雨型。（2）较坡耕地而言，A雨型和C雨型条件下减流量均呈水平阶整地+经果林 > 水保林 > 人工草地 > 自然恢复草地 > 经果林的趋势 ...

Zhongguo shiyan zhenduanxue, 2008 目的研究肝素结合性表皮生长因子（HB-EGF）在早孕人工流产（正常早孕）及早孕自然流产（早期流产）绒毛组织中的表达是否存在差异,并进一步探讨HB-EGF在早期流产病因学中的作用。方法采用免疫组化链霉菌抗生物素-过氧化物酶（SP）连接法检测正常早孕妇女及早期流产患者绒毛组织中HB-EGF的表达。结果正常早孕组与自然流产组绒毛组织内均有HB-EGF表达,各组HB-EGF均表达于绒毛组织滋养细胞细胞膜和细胞浆内。灰度测定与对照组比较,自然流产组绒毛组织内HB-EGF表达明显减弱（t=2.48,P=0.02 ...

, 2019 生物钟是生物体对环境长期适应而形成的自主计时机制。生物钟基因调节人体多项生理活动，比如睡眠-觉醒、激素分泌、细胞代谢和免疫调节等，其目标是使细胞、组织以及器官能够有序、协同作用，并呈现明显的节律。女性生殖功能受下丘脑-垂体-卵巢轴的昼夜节律调控。由于外界因素引起的昼夜节律中断与女性各种生殖功能障碍的发生发展有关，包括月经失调、流产和生育力下降等。本文旨在从月经周期中卵泡发育的调控、排卵 ...
