| 摘 要： | 用透射电镜(TEM)观察螺旋形碳晶须的微观形貌，并作选区电子衍射，分析其结构，可知螺旋形碳晶须的结构为六方晶体．由衍射图的圆弧可知，晶体为有结构的石墨多晶．将衍射图与形貌图对应起来，可知C轴与螺旋轴大致平行．将碳晶须放在压片机上加压，碳晶须在30MPa压强下受压15min后，无被损害之现象．

| Abstract: | Using the TEM to observe the micro shape of coiled carbon whiskers, and analyze their structure by electron diffraction, it can be informed that its structure is hexagonal crystal. From the arc of the diffraction pattern, the crystal body is well organized graphite polycrystalline. When comparing the diffraction pattern with the micrograph, it can be known that the C-axis is almost parallel with the coiling axis. Press the carbon whiskers on the pressure machine under the pressure of 30 Mpa for 15 minutes, but there is no observable damage found in the whiskers. |
