Guangtongxin yanjiu, 2006 文章从密集波分复用（DWDM）系统抵抗恶意侵扰的角度,分析了光放大段（OAS）中掺铒光纤放大器（EDFA）和OAS长度的配置对系统稳定性的影响,认为EDFA累积噪声会随着放大器的级数增加而呈线性增长,而且还会随着OAS损耗的增大而呈指数增长。系统的OAS数量和接收机灵敏度确定时,选择恰当的EDFA配置和OAS长度,可以达到提高系统稳定性的效果。

Jianzhu Gangjiegou Jinzhan, 2007 通过对比美国规范AISC360-05,欧盟规范EN1993以及我国规范GB50017关于轴压构件整体稳定设计的相关规定,发现AISC360-05因采用单一柱子曲线,因而不能充分考虑残余应力等因素对整体稳定承载力的影响;EN1993和GB50017分别采用5条和4条柱子曲线,因而较为科学;GB50017规定的整体稳定系数对大多数截面而言高于EN1993,但由于GB50017采用的抗力分项系数较低,其预测的承载力设计值仍低于EN1993和AISC360-05。

Highly Anisotropic TbCo11Ti: Phase Evolution, Microstructure and Magnetic Properties
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Among the 1:12‐type compounds, TbCo11Ti stands out due to its high Curie temperature and pronounced magnetocrystalline anisotropy. However, its magnetic behavior at room temperature and its phase evolution process have not been clearly established.

Jianzhu Gangjiegou Jinzhan, 2020 温室单层球面网壳的稳定性在设计中起着控制作用,尤其是非对称(半跨均匀)荷载、初始几何缺陷(节点偏差)、矢跨比和拉索预应力等因素对温室单层球面网壳稳定性的影响还有待深入研究。基于构形易损性理论,提出了判断参数对极限承载力影响的指标,即节点构形度的差异系数。利用ANSYS软件对矢跨比分别为1/3、1/5和1/7的K6、K8型温室单层球面网壳进行了整体刚度矩阵的提取,并通过MATLAB自编程序计算得到节点构形度的差异系数,定性分析了各参数对极限承载力的影响与节点构形度的差异系数的关系。研究表明 ...

Zhejiang Daxue xuebao. Lixue ban, 2006 针对一类含有不确定参数的离散时滞系统，研究了当传感器发生增益故障情况下的静态输出反馈鲁棒H∞容错控制器设计问题.系统中的参数不确定性满足广义匹配条件，传感器元件具有部分增益故障.根据Lyapunov稳定性理论和线性矩阵不等式(LMI)方法，分别给出了含有时滞记忆和无时滞记忆静态输出反馈鲁棒容错镇定控制器以及静态输出反馈H∞容错控制器的存在条件.通过求解一组线性矩阵不等式可以得到使得闭环系统渐近稳定并且H∞范数小于给定界y的鲁棒容错控制器.最后通过仿真示例说明本文提出设计方法的正确性.

Dianci bileiqi, 2013 研究了不同温度（900～1040℃）下烧结的ZnO-Bi2O3系叠层片式压敏电阻器（ML-CV）的热稳定性和8/20μs电流脉冲冲击稳定性,发现1000℃烧结的MLCV试样的稳定性最好,其压敏电压变化率的温度系数低于1.67×10-4/K,电脉冲冲击后压敏电压和分线性指数的变化率分别仅为0.25%和4.27%。然后分析了烧结气氛对MLCV在1 mA直流负载作用下压敏电压稳定性的影响,发现当垫料中添加剂的质量百分比比试样中添加剂质量百分比高20%时,MLCV试样压敏电压的稳定性最高。

Stability Analysis of Deep Foundation Pit of Hechang Trade Center in Quanzhou [PDF]
, 2017 基坑力学特性与变形机理复杂，且具有较强地域性，在进行基坑支护设计及施工时多采用工程经验类比法，为确保基坑的稳定性，需要对基坑稳定性进行较为详细的分析验证。本文针对泉州和昌贸易中心大型深基坑工程，在总结基坑稳定性分析基本原理及验算公式的基础上，进行整体、抗隆起、抗倾覆及抗冲剪稳定性分析验算，得到基坑四种稳定性安全系数，以验证此基坑的稳定性，在此基础上，深入探讨了土层粘聚力、内摩擦角及重度和桩入土深度等因素与基坑四种稳定性安全系数的相互关系，对于基坑工程的稳定性分析具有一定参考意义。本文主要研究结论包括： （
