霓虹招牌修复保育说明（送审稿）
RC-87 · 1987
「生机」茶铺招牌为 1987 年初制霓虹招牌，2019 年停电故障后损坏。本次修复遵循最小干预、可逆原则：「生」字主笔与「机」字弯圈原件原位保留并测绘气口，老式镇流器以 RC-87-B01 编号移存库房；仅对变形不可逆的主笔以新制件 RC-87-C01 替换，管径（6mm）与气体配方（Neon 99.5%，5.2 mTorr）与原件一致。全部原件与替换件已逐件编号并双人签字，可随时凭编号甄别真伪。
The "Sheng Ji" teahouse sign is a neon installation originally made in 1987 and damaged in a 2019 power failure. Conservation followed minimum-intervention and reversibility: the main stroke of "sheng" and the loop of "ji" are retained in place with electrode ends documented; the aged transformer is stored under tag RC-87-B01. Only the irreversibly deformed main stroke was replaced with new member RC-87-C01, matched to the original 6 mm tube and gas recipe (Neon 99.5%, 5.2 mTorr). Every original and replacement part is double-signed and identifiable by tag at any time.
