So in the late 1800s and early 1900s, celluloid accessories were everywhere -- buttons, jewelry, eyeglass frames, toys, and little hair combs that ladies would wear.

因此， 在 1800 年代末和 1900 年代初，赛璐珞配饰无处不在——纽扣、珠宝、眼镜框、玩具和女士们会戴的小发梳。

In daily life, you can find SMAs in simple objects such as eyeglass frames and bra wires, which can regain their shape even after being bent or twisted.

在日常生活中，您可以在眼镜框和文胸钢丝等简单物体中找到 SMA，即使在弯曲或扭曲后也能恢复原状。
