This evolution rate of the partial excess stochastic entropy is equivalent to the partlal excess stochastic entropy production, as well as the stochastic excess entropy production rate based on the stochastic potential npproach. It appears also as an eqivalent quantity of the Gibbs excess entropy production for the Polsson distribution. The macroscopic stability of chemical reaction systems is dominnted by this new stochastic quantity when the local equilibrium thermodynamics is broken down .展开更多

Based on the multiple compounding of the charactemtic town planning, it is significant to combine tiie universal viewpoint widi traditional small town planning. This paper by combining with “universaT viewpoint introduced the transformation of traditional small town planning in theory and practice, and combed the planning stategies from the 4 a^ects of “all level”,“all space”, “all element^,and “all dimension”. Based on the master plan of Guzhu Town in Heyuan, specific strategies were put forward from the 6 dimensions of resoutce analysis, spatial layout, industtiai construction, traffic connection, ecological control and system update, to provide references for the planning of characteristic towns.展开更多
为研究热老化时间及测试温度对油纸绝缘时域介电特性的影响,以及更好地应用时域介电响应技术评估变压器油纸绝缘老化状态,首先进行了不同热老化时间及不同测试温度下油纸绝缘绕组模型的极化/去极化电流(polarization and depolarization...为研究热老化时间及测试温度对油纸绝缘时域介电特性的影响,以及更好地应用时域介电响应技术评估变压器油纸绝缘老化状态,首先进行了不同热老化时间及不同测试温度下油纸绝缘绕组模型的极化/去极化电流(polarization and depolarization current,PDC)测试,然后通过扩展Debye模型实现时域介电测试技术间转换,深入研究了热老化时间及测试温度对时域介电特性及其特征参量的影响,最后提出运用时间及幅值平移因子构造电流标准主曲线以消除测试温度对时域介电特性影响的方法。结果表明:油纸绝缘时域介电特性及特征参量受热老化时间及测试温度影响较大;在应用时域介电响应技术评估变压器油纸绝缘状态时,必须考虑测试温度的影响,否则将导致评估结果失实;通过本文方法绘制的电流标准主曲线不仅能消除测试温度对时域介电特性的影响,还能实现在不额外延长实际测试时间的前提下,获得更多反映油纸绝缘状态的时域介电响应信息,并通过实验验证该方法的有效性。展开更多
