由于基于实物的模拟，特效模拟工具必须是直观的、动态可控的，这样才能保证真实感和模拟效果的质量。

To this end, special effects simulation tools, while physically based, must be able to be dynamically controlled in an intuitive manner in order to ensure believability and the quality of the effect.

整个实验过程可同时在计算机上和模拟实验板上直观的展现出来。

The whole experimental process can be displayed in both computer and the simulation experiment interface at the same time.

The way we use technology to overcome that is we have a lot of simulations and visualizations set up, built around in the virtual spaces.

我们用技术来解决这个问题的方法,是我们用很多模拟实验,以及直观化实验，放在模拟空间里。
