Gongye shui chuli, 2023 采用电絮凝+微气泡臭氧氧化耦合工艺处理页岩气压裂废水，考察了不同工艺、初始pH、电流密度、臭氧投加量、反应时间等因素对压裂废水COD去除效果的影响。结果表明，电絮凝+微气泡臭氧氧化耦合工艺对页岩气压裂废水具有较好的处理效果，在初始pH为9.5、电流密度为15 mA/cm2、臭氧投加量为80 mg/L和反应时间为60 min最优反应条件下，压裂废水COD去除率可达到85.96%。电絮凝与微气泡臭氧氧化之间存在协同作用，碱性环境更有助于页岩气压裂废水的电絮凝耦合微气泡臭氧氧化处理 ...

, 2016 监控单元在现代航空航天飞行器中有重要作用,通常置于相对封闭的薄壁容器内。为提高监控单元可靠性,需要准确描述其环境条件,包括其声学、振动状态和热环境,三者存在相互作用,其结构和声响应是耦合的。本文通过一个典型结构模型,建立热-声-振耦合响应分析方法,研究监控及控制单元的多物理环境特征。首先建立考虑热膨胀效应和热软化效应的热-结构动力学控制及有限元模型,其次进行不同声激励下的声-振耦合数值分析;用该耦合方法预测了该盒子壁面的声传递损失,建立了监控单元薄壁容器多物理环境与声 ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The immunosuppressive milieu of hepatocellular carcinoma (HCC) remains a major obstacle to durable antitumor responses. Mechanical‐energy‐driven piezocatalysis provides a noninvasive means of inducing oxidative damage and immunogenic tumor destruction; however, inefficient utilization of piezoinduced charges and insufficient localization of ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT High‐yield photocatalytic H2O2 production in sacrificial agent‐free pure water constitutes a critical bottleneck requiring urgent advances in energy catalysis. Although ZnIn2S4 (ZIS) exhibits favourable visible light absorption, it is plagued by severe bulk charge carrier recombination and scarce accessible surface‐active sites.

Gaoya dianqi, 2013 理论分析了定向耦合器监测端脉冲信号波形与辐照等效源波形的关系,实验研究了在定向耦合器输入功率不变的前提下,直通端阻抗的变化对耦合端监测功率的影响,证明了理论分析的正确性,仿真分析了对称定向耦合器耦合端和直通端的相位差对监测波形的影响。结果表明:对于非线性互联系统,在保证系统响应相同的条件下,注入电压与辐照场强的关系是线性的;在系统端口匹配的情况下,监测电压与辐照等效源电压为线性关系;耦合端和直通端的相位差会导致监测波形畸变,应选用反对称或非对称定向耦合器作为监测设备。

Shuitu Baochi Xuebao, 1994 该文通过对春小麦２年田间水肥试验结果分析表明：①水肥对春小麦产量，收入有明显的主效应与交互效应，在试验范围内（水分为９％－１８％，肥料为５－２０ｋｇ／亩），水分平均主效应（以１．５％个土壤水分为１个单位）＞肥料平均主效应（以２．５ｋｇ／亩为１个单位）。②春小麦的水肥产量，收入效应为报酬递减函数，生产中存在一个经济合理的水肥耦合区，通常肥料为５－１６．０ｋｇ／亩时，需９％－１７．８％的水分与之配合；
