The other metric that sometimes pops up on MicroSD cards is the Application Performance Class. Rather than referring to the minimum speed for writing predictable data in large chunks to the card, this number references the capability to random smaller read and write operations, like you might have when running an application stored on the card. There are currently only two options here, A1 and A2, with the A2 being the faster, newer standard. While there are some exceptions, most of the V30 or higher MicroSD cards I see for sale online are A2, but it's worth keeping an eye out for if you plan on using the card in your phone.，详情可参考体育直播
这一发现激发了研究团队的探索热情。在对材料的纹理控制上，他们利用高精度的电子束光刻工具，在聚合物薄膜上“微雕”出各种图案。当薄膜被浸入不同液体中时，会发生可逆的局部膨胀或收缩，从而隐藏或显示预设的纹理图案。在颜色控制上，则采用了一种精巧的光学结构，将薄膜夹在两个极薄的金属层之间，使之构成一个“法布里—珀罗谐振腔”（一种光学谐振装置）。这一结构如同给材料装上了精密的“调音器”，可精确控制薄膜不同区域的溶胀程度，改变器件对特定颜色光的反射率，从而呈现不同的结构色。
