Wrap-around Contact Solar Cell 卷包式太阳能电池
There is one thing I need to estimate first –the area of contact between the ground and the bubble wrap.
当然,还有一件东西是我们必须首先考虑的——那就是地面与汽泡纸接触面的大小。
The problem is difficult because BPA is used for most types of plastic foil in which you wrap food. Thus, a direct contact with the body is established and it occurs on a daily basis.
更困难的是,BPA是最常用在保鲜膜中的原料,人们每天都不可避免的会有直接接触。
Do not wrap it with conduct material to avoid the damage caused by the direct contact between the metal and battery. Keep the battery in day places.
请用不导电材料包裹电池,以避免金属直接接触电池,造成电池损坏,将电池保存阴凉干燥处。
