其它流程，如混入聚合体热敏细丝通过自加固原理进行聚合以产生成模。

The bulb works by passing an electric current through a thin filament, which heats it up.

灯泡的工作原理是让电流通过一根细细的灯丝，使它变热。

A sarcomere contains both thin filaments, made up mostly of two light and twisty actin strands, and thick filaments, composed of thicker, lumpy-looking myosin strands.

肌节既包含细丝，主要由两条轻盈而扭曲的肌动蛋白链组成，也包含粗丝，由更厚、看起来块状的肌球蛋白链组成。

One of the fossils is made of thin filaments, divided into compartments that the researchers think are cells.

其中一块化石由细丝组成，被分成研究人员认为是细胞的隔间。

Each sarcomere is separated by what's known as a Z line at either end, which is just a border formed by alternating thin filaments in a kind of zig zag pattern.

每个肌节在两端都被一条 Z 线分开，这条 Z 线只是由以之字形图案交替排列的细丝形成的边界。
