Application of artificial intelligence to ultrasound imaging for benign gynecological disorders: systematic review

open access: yesUltrasound in Obstetrics &Gynecology, Volume 65, Issue 3, Page 295-302, March 2025.
ABSTRACT Objective Although artificial intelligence (AI) is increasingly being applied to ultrasound imaging in gynecology, efforts to synthesize the available evidence have been inadequate. The aim of this systematic review was to summarize and evaluate the literature on the role of AI applied to ultrasound imaging in benign gynecological disorders ...

陶瓷超滤膜处理煤矿矿井水的中试研究

open access: yesGongye shui chuli, 2020
为解决煤矿矿井水水量和水质波动大而导致浸没式超滤膜产水量低,易污堵和难清洗的问题,开展了陶瓷超滤膜在煤矿矿井水处理系统中的中试研究。结果表明,在超滤进水投加13~15 mg/L聚合氯化铝的条件下,即使进水浊度在数小时内跃升至100 NTU,陶瓷超滤膜均可在260 L/(m2·h)的目标运行通量和315 L/(m2·h)的挑战运行通量下稳定运行。产水浊度稳定< 0.1 NTU,优于后续纳滤系统进水要求。

超滤膜平均孔径测算的新探讨 [PDF]

open access: yes, 1992
利用扫描电镜法测定超滤膜底表面上总孔面积与该底总表面积之比,再结合哈根——泊肃叶定律来推算超滤膜皮层的平均孔径。这样所得的超滤膜平均孔径比起原先单独使用扫描电镜法或哈根—泊肃叶法 ...
