用石英晶体切成厚0.3—0.8厘米的定向切片进行光学性质观察后,再放置在氟氢酸中腐蚀进行观察。 1.用偏光显微镜检验偏光面旋转方向,确定左族或右旋晶体: 将石英垂直c轴切片在正交偏光镜和聶氏镜下生成中间空心状干涉象(图1)。只有具
After the optical properties were observed by slicing the quartz crystal into oriented slices with a thickness of 0.3-0.8 cm, the films were observed for corrosion in hydrofluoric acid. 1. Using polarized light microscopy examination of the direction of rotation of the polarizer, to determine the left or right-handed crystal: the vertical quartz c-axis section of the orthogonal polarizer and Nirvitz mirror to generate intermediate hollow interference image (Figure 1).
