These moduleunits are assembled annually in a Wildlife Management Area site chosen for optimal 24/7 polar bear viewing.
每年野生动物管理区就会搭建这样的小屋，在这里一周七天、一天二十四小时都能看到北极熊。

The advantage of this design is that high reliable and module-realizable power supply can be achieved, and different voltage output can be realized through varying the amount of moduleunits.
研制的电源可靠性高，可实现模块化，可通过增减模块单元的数量，满足不同输出电压的需要。

There are four units and one module task in each module.
