🔬 科技与市政树 Technology & Civics Tree

文明6的研究系统分为两条独立的树：科技树（Technology Tree）由科研值驱动，解锁单位、建筑和改良设施；市政树（Civics Tree）由文化值驱动，解锁政策卡、政体和部分建筑。每项科技/市政都有一个"尤里卡/启发"（Eureka/Inspiration）条件，完成后减少50%研究成本。

Research Strategy Tips

Always aim for Eurekas: A 50% discount on every tech/civic adds up enormously. Plan 2-3 turns ahead to trigger boosts before researching.

Beeline key techs: You don't need to research everything in order. Focus on the techs that unlock your victory condition or critical military upgrades.

Campus placement: Adjacent to 2+ mountains = +4 science minimum. Build Campuses early in every city for passive science generation.

Theatre Square for civics: Culture accelerates civic research. Even non-culture players should build Theatre Squares for faster policy unlocks.

Great Scientists: Some Great Scientists provide free tech boosts or instant research completion. Prioritize these in late game for space race techs.

Era Score & Research

★ Golden Age bonus: In a Golden Age, your cities gain +10% science/culture. Time your research of critical techs during Golden Ages for maximum efficiency.

★ Overflow research: If you finish a tech with excess science, the overflow carries to the next. Switching to a nearly-complete tech wastes less overflow.

★ Tech trading (GS): In Gathering Storm, you can trade diplomatic favor for techs via the World Congress. Late-game this can skip expensive technologies.
