对于天然丝，他们的研究方法采用计算机模型，来帮助确定使天然丝材料具有卓越力学特性的分子与原子机制。

With silk, that means using computer models that help determine the molecular and atomic mechanisms responsible for the material's remarkable mechanical properties.

现在， 新的模型使用漂亮的， 有光泽的镀铬六角形镙丝。

Now, new models use nice, shiny chrome, hex - head screws.
