A new magnetic material breakthrough has been achieved by scientists, which can indirectly lead to the end of the current memory and storage crisis.

大多数冰箱贴虽单个重量不大，但如果是大面积整块磁贴、金属材质或立体装饰款，长期集中贴在某一区域，就会形成持续的局部压力。外层金属面板在长期施压下，可能出现细微的形变；中间的发泡层虽有一定弹性，但长期受力会逐渐失去回弹能力，进而影响门体的平整度 [4]。而门体不平整又会直接破坏密封条的密封效果，导致冷气外泄，增加冰箱能耗，甚至缩短压缩机的使用寿命。
