Policy Studies Journal, EarlyView.ABSTRACT Why did Australia go from the White Australia Policy, which excluded non‐whites, to institutionalizing multiculturalism policy in the 1970s? This question defies traditional political ideologies of the major political parties, which had long supported the White Australia Policy. This article is a rare empirical demonstration of the Five‐Thread

Dianci bileiqi, 2019 支柱瓷绝缘子的脆性断裂故障给电力系统的安全稳定运行造成了严重的影响,而支柱瓷绝缘子在动态载荷下的运行条件要更加恶劣,断裂故障亦更加频繁。为分析动态载荷下支柱瓷绝缘子的应力特征分布规律,基于热-结构耦合数学模型建立了支柱瓷绝缘子有限元数值仿真模型,并分别建立了相应的动态风力、短路电动力和地震动态载荷的数学模型,对动态风力、短路电动力和地震波作用下的应力特征及最大拉应力动态变化特征进行计算分析。

Gaoya dianqi, 2008 随着同步相量测量技术的发展和对电力系统的深入研究,人们认识并观察到电力系统中的功角扰动以远低于光速的速度传播。大规模电力系统的连续体模型突破了对传统认识的局限性,用波动理论这一崭新的视角研究电力系统的机电动态。本文根据经典物理学中矢量场理论,推导出电力系统连续体模型中的非线性波动方程,求出均匀电力系统在平衡点附近的解析解,分析了机电波传播幅度变化的内在机理。最后用一个由64台发电机组成的环形仿真系统,证明了大规模电力系统连续体系机电波模型的正确性。作为一种新的数学模型 ...
