## 概述

Interactive visualization of thermal expansion - explore how materials expand and contract with temperature changes. Features linear expansion formula ΔL = α·L₀·ΔT and volume expansion ΔV = β·V₀·ΔT. Six preset materials (Aluminum α=23×10⁻⁶/°C, Copper α=17×10⁻⁶/°C, Steel α=12×10⁻⁶/°C, Glass α=9×10⁻⁶/°C, Concrete α=10×10⁻⁶/°C, Water β=207×10⁻⁶/°C). Heat and cool animations with temperature changes from -100°C to +500°C, adjustable magnification factor (10-200x) to visualize tiny expansions, real-time material bar animation showing expansion/contraction with color-coded temperature indicator. Three interactive charts: Length vs Temperature curve with real-time tracking, Expansion Coefficient Comparison bar chart across materials, and Volume Expansion (ΔV/V₀) vs ΔT plot. Parameters: initial length L₀ (0.1-10 m), temperature change ΔT (-100 to +500°C), initial temperature T₀ (-50 to +100°C), and animation speed. Educational content covers linear expansion, volume expansion with β ≈ 3α for isotropic solids, real-world applications (expansion joints in bridges, thermometers, bimetallic thermostats), and water's anomaly with ice floating and insulating lakes. Multi-language support (zh, en, es, fr, de, ru, pt).
