2025年12月，国家互联网信息办公室公布《人工智能拟人化互动服务管理暂行办法（征求意见稿）》，首次对“AI陪伴”类服务作出系统性规范，划定制度红线，专门设立针对未成年人用户的条款，明确未成年人模式的使用权限与监护人管控功能等。技术开发者作为风险防控的第一道关口，应当严格落实主体责任，优化算法设计，加强全流程管理，确保产品服务安全可靠；学校作为教育主阵地，应积极推进人工智能通识教育，在提高学生实践技能的同时，也注重培养批判性思维，引导他们正确认识技术边界；家庭则需做好陪伴与守护，用现实的温度帮助青少年建立与真实世界的情感联结。

\newif inside macros fails on the second call. Since \newif creates a global flag, calling it again raises “already defined”. All boolean flags must be declared once at the global level.
The power behind the high gradients comes from CERN’s Xboxes, the X-band RF systems that dominate the experimental hall. Each Xbox houses a klystron, modulator, pulse compressor, and waveguide network to generate and shape the microwave pulses. The pulse compressors store energy in resonant cavities and then release it in a microsecond burst, producing peaks of up to 200 megawatts; if it were continuous, that’s enough to power at least 40,000 homes. The Xboxes let researchers fine-tune the power, timing, and pulse shape.
