 == Phonons in Perfect 4H-SiC
 
-These phonons were categorized into two groups and discussed separately, according to their electrical polarities:
-  negligible-polarity phonons (i.e., zero or very weak electrical polarity), and strong-polarity phonons.

+Owing to the distinct behaviors arising from their different electrical polarities,
+  Raman-active phonons were categorized into two groups:
+  negligible-polarity phonons (i.e., having zero or very weak electrical polarity),
+  and strong-polarity phonons.
+The negligible-polarity phonons exhibited minimal dependence on the wavevector direction
+  (see the intersection of gray solid lines and orange dashed lines in @figure-discont b and c),
+  and were therefore usually analyzed at the #sym.Gamma point regardless of the incidence configurations;
+specifically, there were eight such modes
+  labeled A#sub[1]-1 to A#sub[1]-2, E#sub[1]-1 to E#sub[1]-2, and E#sub[2]-1 to E#sub[2]-4,
+  according to their irreducible representations in the C#sub[6v] group and in order of increasing frequency.
+In contrast, the strong-polarity phonons displayed significant anisotropy,
+  and required analysis under specific incidence configurations.
+In this paper, we focused on incidence within the zOx plane,
+  where three modes were present and named according to their vibration directions:
+  TO-zOx (vibrating in the zOx plane and roughly perpendicular to the incidence direction),
+  TO-y (vibrating along the y-axis), and LO (vibrating roughly parallel to the incidence direction).

+// 第二段：我们具体计算了模式对极性的依赖。可以看到，弱极性声子的变化极小。与实验比较，也验证了我们实验的准确性。

+// 第三段：有两个弱极性模式还没有在实验上看到过。我们通过计算知道了它们的强度，并看到了其中一个。

+// 第四段：声子模式的强度可以从理论上得到解释。
 
 === Negligible-polarity Phonons
