城市雕塑作为一种公共艺术,是城市景观的重要部分,同时也是城市精神文化的载体。近年来,城市雕塑在表现城市发展成就和城市地域特色等方面起到越来越重要的作用。然而在国际著名的风景旅游城市——张家界市,目前的城市雕塑几乎不能完整体现张家界本土文化特色,且城市雕塑的规划设计与可持续发展不受重视。本文通过实地踏勘与问卷调查,分析张家界城市雕塑的现状及存在的不足,结合张家界地域文化特色及城市发展定位,提出富有张家界特色的城市雕塑四大主题,并对城市雕塑的空间布局做出具体指引。以期对今后张家界城市雕塑的规划设计与建设提供参考借鉴。

Photovoltaic (PV) modules, as essential components of solar power generation systems, significantly influence unitpower generation *** service life of these modules directly affects these costs. Over time, the performanceof PV modules gradually declines due to internal degradation and external environmental *** cumulativedegradation impacts the overall reliability of photovoltaic power generation. This study addresses the complexdegradation process of PV modules by developing a two-stage Wiener process model. This approach accountsfor the distinct phases of degradation resulting from module aging and environmental influences. A powerdegradation model based on the two-stage Wiener process is constructed to describe individual differences inmodule degradation processes. To estimate the model parameters, a combination of the Expectation-Maximization(EM) algorithm and the Bayesian method is employed. Furthermore, the Schwarz Information Criterion (SIC) isutilized to identify critical change points in PV module degradation trajectories. To validate the universality andeffectiveness of the proposed method, a comparative analysis is conducted against other established life predictiontechniques for PV modules.

鸭绿江断裂带为吉林省东部山区规模较大的北东向断裂带之一,与省内闻名的依兰—伊通断裂带、敦化—密山断裂带基本平行展布,纵贯我省南部中朝准地台和北部天山—兴安地槽两个一级大地构造单元。鸭绿江断裂带在长期活动中对沉积建造、岩浆活动具有重要的控制作用,因而成为重要的构造岩浆岩带。鸭绿江断裂带在发展演化过程中,对有色金属、贵金属都有明显的控制作用,因此鸭绿江断裂带也是我省东部的重要成矿带之一。
