"note that"

问题描述:

"note that"
经常在英语中看见note that这个短语,而汉语中好象没有太确切的翻译.请问下句中的note that
To make the phrases "low-indesity" and "large area" easier to understand,note that in order to produce 1000 kwh of electricity per year,a home owner in cloudy Europe needs to use eight square meters of solar panels.

为了更容易理解短语“低密度”和“大面积”,注意,在多云的欧洲,一个家庭为了得到一年1000千瓦时的电需要使用8平方米的太阳能板.
