城镇生态化视角下三峡库区人口-经济-环境(PEE)耦合协调发展
Shuitu Baochi Xuebao[目的] 探索PEE系统的互动耦合特征,可为三峡库区城镇生态化发展提供理论支撑和量化依据。[方法] 在2000—2020年三峡库区PEE系统综合评价基础上,运用耦合协调度模型、引力模型和障碍度模型对系统耦合协调度的时空演化特征、空间联系特征及主要障碍因子进行实证研究。[结果] (1)2000—2020年库区PEE系统综合发展水平呈逐步上升态势;(2)研究期内系统的耦合协调度基本不变,协调等级不高,协调类型呈"西南-东北""中部-北部"的空间特征,总体呈良性上升发展趋势;(3 ...

Gaoya dianqi与交流配电系统一样，表征直流配电系统特征指标的直流电压、直流电流也在时刻变化着且其变化幅度、变化频度均具有很强的随机性，导致接入电网的照明类负载灯光照度的随机变化，引起感受体—人对照度变化的视感即常说的闪变。相比于交流配电系统已有公认的、标准化的闪变测量方法，直流配电系统的闪变测量方法目前还处于研究探讨之中。文中基于直流配电系统的特点，在分析传统交流配电系统平方解调闪变测量方法的基础上提出了一种适用于直流配电系统的去平方解调闪变测量方法；仿真分析表明：该方法准确度高 ...
