The ISS does have its own defenses, of course. Fabric-y buffers envelope some of the systems, and a bumper called the Whipple Shield helps blunt impact.

我国向联合国教科文组织提交的列入人类非物质文化遗产代表作名录的申请项目，从早期重视对濒危非遗项目的抢救保护，逐渐转向对于具有人类创造性、认同性、可持续发展且存活良好的传统文化项目的关注。项目本身的体量也在不断扩展，从“单个技艺”（昆曲、古琴艺术、木拱桥传统营造技艺、雕版印刷技艺等）向内涵丰富的综合性项目（二十四节气、传统制茶技艺及其相关习俗等）转化。这一变化，反映出我国非遗保护工作取得的巨大成就。
