通过门样机施加等效风压荷载和人群挤压荷载，模拟门受荷载作用下的不利工况。

To simulate the vulnerable working conditions of APG under the applied load, place the substituted load equal to the wind load and the crowd extrusion load on the prototype of APG.

目前他们模拟了产生重叠噪音信号的基本回路，基于噪音的与门和或门，还有其他的一些元件。

So far they have simulated basic circuits for generating composite noise signals, as well as noise-based and and or logic gates, among other components.

如果不需要非易失性门，考虑使用器件共用在模拟和混合信号系统中：数字电位器(图1)。

If you need only a few nonvolatile gates, consider using a component common in analog - and mixed-signal systems: the digital potentiometer (Figure 1).
