流动镶嵌模型 Fluid Mosaic Model

磷脂双分子层是细胞膜的基本结构，细胞膜的流动性和其中的各种蛋白质和分子在维持细胞功能中起着关键作用。
The phospholipid bilayer is the basic structure of the cell membrane, and the fluidity of the cell membrane along with the various proteins and molecules within it play a key role in maintaining cellular functions.

为了更直观地理解这些结构及其功能，我制作了多个手工模型，涵盖磷脂双分子层、通道蛋白、整合蛋白、螺旋蛋白、球蛋白、碳水化合物和糖蛋白等。
To better understand these structures and their functions, I have created several handcrafted models, including those representing the phospholipid bilayer, channel proteins, integral proteins, peripheral proteins, globular proteins, carbohydrates, and glycoproteins.

这些模型适用于生物学课程，特别是在讲解细胞生物学和生物化学时使用。旨在通过物理模型的展示，帮助学生深入理解细胞膜的组成和功能，增强教学的互动性和趣味性。
These models are suitable for biology courses, especially when teaching cell biology and biochemistry. They are designed to help students gain a deeper understanding of the composition and functions of the cell membrane through the display of physical models, enhancing the interactivity and fun of teaching.

收纳盒抽屉组装说明   Assembly Instructions for Storage Box with Drawers：

你可以选择安装磁铁使抽屉更加牢固，选择的磁铁是5*2mm，但是我量出来略小一圈，安装可以选择一些硬的东西将磁铁按压进去固定就可以了。

You can choose to install magnets to make the drawers more secure. The recommended magnets are 5x2mm, but I found them to be slightly smaller than expected. For installation, you can use a hard object to press the magnets into place to secure them.
