Nana L'ange protecteur

Nana L'ange protecteur 是法美艺术家妮基·德·圣法勒创作的公共雕塑，位于苏黎世中央火车站主大厅上方。作品属于她的“Nana”系列，呈现一位拥有蓝色身体和金色翅膀的女性守护天使。雕塑高约十一米，重约一点二吨，鲜艳服饰为车站空间增添了醒目的色彩。天使双手各握一个瓶子，树脂材料与水彩颜料共同构成了它的表面。作品的色彩需要谨慎维护，工作人员使用掸子和压缩空气清洁金色翅膀与彩色衣饰。

这件艺术品由苏黎世的Securitas赠送，用于纪念瑞士联邦铁路成立一百五十周年。妮基·德·圣法勒亲自监督了安装，雕塑则从美国分成三部分运抵苏黎世。它将女性形象、守护主题和充满动感的造型带入日常交通空间。Nana L'ange protecteur 面向经过车站的人群开放观看，也属于轮椅可通行的艺术地点。 blenders? Need Chinese only, Securitas Latin okay. "水彩颜料" source. Sentence issue "艺术品" etc. Count maybe. Ensure no foreign "Nana". Fine. But "轮椅可通行" from property. "开放观看" inference? public art accessible everyone source. Fine. Need 150-300 words, Chinese chars around 230, likely okay. However first paragraph maybe sentence 5 all. We have 9 sentences. Sentence 1 etc. Need no "Nana series" quote? entity source quote not prohibited, draw. They said descriptions never published as stands, quotes? We can use series name. Fine. Could avoid exact anniversary as count? Historical, okay. Rule no counts likely no counts maybe means no numerical current counts. But given guidance "Prefer ... numbers" and historical details. Fine. Note "flask" translated bottle. Great. Wait Chinese only: "Securitas" proper name is Latin, allowed. "Nana" proper name. There is no English. Good. bidi? no. Need maybe "苏黎世中央火车站" source says Zurich main station, natural. Final only.
