动态知识模型

我们的 DKM 收藏将会不断扩大。其中一些已经开发完成，另一些正在开发中或处于项目阶段。一旦 DKM 的开发成本获得资助，它将采用 LGPL 许可发布；否则，它将采用 CC by-nc-nd 许可。

交互式几何

通过该模型，用户可以构建交互式几何图形。得到的图形随后可以用鼠标进行变形。通过使用脚本，我们创建了种类繁多的图形，当应用循环或递归时，其中一些图形会变得非常复杂。该 DKM 将由 Dr. Geo 改编而来，可作为 DKM 模块和独立应用程序共同使用。 | canvas r f u | canvas := DrGeoSketch new axesOn scale: 500. r := canvas float: 2 at: 0 @ -0.1 from: 0 to: 4 name: 'r' showValue: true. f := [ :x | r value * x * (1 - x) ]. canvas ray: 0@0 to: 1@1. canvas plot: f from: 0 to: 1. u := canvas pointOnLine: (canvas segment: 0@0 to: 1@0) hide at: 0.2. 100 timesRepeat: [ | v | v := canvas " v sequence term " point: [ :previous | previous point x @ (f value: previous point x) ] parent: u. canvas segment: u to: v. u := canvas " u is a point on the Ray (0,0) (1,1) " point: [:previous | previous point y @ previous point y ] parent: v. v hide. u hide. canvas segment: u to: v. v := u]

气体模拟器

该模型允许定义一个矩形外壳以及任意数量的壁面和氩原子。该模型模拟了通过漫反射与壁面相互作用的理想气体，或者同时具有壁面相互作用和 Lennard-Jones 原子间势能的真实气体。在模拟过程中，包括外壳在内的所有壁面的温度设定值都可以通过鼠标进行调节。此外还提供任意数量的覆盖矩形区域的温度探头。 GasSimulation new fenceOrigin: 0@0 corner: 300@200; addWallFrom: 100@0 to: 80@85; addWallFrom: 100@200 to: 80@105; addMolecules: 50

时间轴

该模型允许表示包含任意数量事件的时间轴。每个事件包括日期和描述。对于事件非常分散的时间轴，可以使用 shrink 消息进行压缩。 Timeline title: 'Five Defining Moments of Alexander' :: addEvent: 'Tutelage by Aristotle.
