小狐化学实验室 vs PerturbLab

小狐化学实验室是一款面向中学生的化学实验学习工具，围绕常见中考化学实验，把实验步骤、实验现象、化学方程式、易错点和微观原理整合到一个可交互的学习流程中。 主要功能： 1. 化学实验训练 覆盖制取氧气、制取二氧化碳、粗盐过滤、蒸发结晶、金属活动性、酸碱盐反应等中学常见实验。每个实验包含仪器选择、操作顺序、现象判断和扣分点训练。 2. 实验原理微观分析 用粒子视角解释实验背后的变化，例如过氧化氢分解生成氧气、碳酸盐与酸反应产生二氧化碳、粗盐过滤中的分离过程等，帮助学生从“背结论”走向“理解为什么”。 3. 3D 可视化学 提供轨道杂化、σ键/π键、甲烷空间构型、VSEPR模型、离子晶格溶解等可视化模块，把抽象化学概念变成可以观察和对照理解的模型。 4. 学习进度与错因记录 记录实验掌握情况、练习结果和错因，方便学生复习薄弱环节。 适合： - 初中化学实验复习 - 中考实验操作与实验题训练 - 想用可视化方式理解化学概念的学生 - 家长和老师辅助讲解实验原理 Privacy Policy: http://mindkey.xyz/index.php/mindkey/privacy-policy/ Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

See how a tiny change at the start grows into a completely different world. PerturbLab is a chaos and physics simulator with 176 experiments – Double Pendulum, Three-Body orbits, the Lorenz butterfly, Game of Life and more – that run live on your device. Free, offline, no ads, no account. WHAT YOU SEE • Side-by-side comparison: the same system runs twice, one copy nudged by a tiny amount. Watch them move together, then split apart. Overlay both runs and follow the distance between them on a live log-scale chart. • Simple rules, surprising order: Langton's Ant, cellular automata, chip-firing and walkers grow complex patterns from a single rule. • Tipping points: percolation, the Ising magnet, epidemics, traffic jams and synchronization sweep across a critical value so you can see the sudden change happen. WHO IT IS FOR • Students: see sensitive dependence, strange attractors and phase transitions instead of just reading about them. • Teachers: a ready-made classroom demo on iPhone or iPad, with side-by-side runs in landscape on iPad. • Curious minds: endless generative patterns to watch, tweak and share. 176 EXPERIMENTS IN 9 CATEGORIES • Classics and pendulums: Double Pendulum, Triple Pendulum, Spring Pendulum, Driven Damped Pendulum • Celestial and particles: Three-Body, Restricted Three-Body, N-Body, Billiards, Magnetic Pendulum • Oscillators and circuits: Duffing, Van der Pol, Chua's Circuit, Coupled Oscillators • Maps: Logistic Map, Hénon Map, Standard Map, Arnold's Cat Map, Clifford and De Jong attractors • Flows: Lorenz, Rössler, Thomas, Aizawa, Halvorsen and the Sprott family of chaotic flows • Fields and grids: Gray-Scott reaction–diffusion, Kuramoto oscillators, sandpiles, aggregation • Visual systems: fractal ferns, dragon curves, flow fields, iterated function systems • Rule emergence: Langton's Ant, Wireworld, turmites, rule 184 traffic, Pascal's triangle modulo n • Phase transitions: percolation, Ising magnetization, epidemic threshold, forest fires, Kuramoto locking NEW IN THIS VERSION • A short note for every experiment: what it is, what to watch, what to try • Favorites, recent experiments and search • Share the current picture as an image, with the settings that made it • Opens where you left off • Divergence chart and full dark mode • Now in English, Simplified Chinese, Traditional Chinese, Japanese, German and French CONTROLS Presets (Calm, Chaotic, Dramatic), perturbation and trail sliders, 0.25x to 4x speed, random seeds, pause and reset. Every run is reproducible from its seed. PRIVACY Everything runs on your device. PerturbLab has no ads, no tracking, no account and collects no data.
