今发现以水牛角瓣充广角瓣者,现提供二者主要鉴别特征如下。广角瓣为犀科动物非洲产黑犀(Rhinoceros bicornis) 或白犀(R.simus)的角经加工而成。广角瓣多以第二角或小形角锯段后纵向劈成长方瓣,灰黑色或黄白色。质坚实,有韧性。锯断面光滑平坦,丝纹细腻,有光泽;纵劈裂面有明显纵向顺直丝纹,并有撕裂的毛刺翘起,形如白发。气微香,味淡。 Now we found that filling the wide-angle flaps with buffalo horn flaps provides the main distinguishing features of the two as follows. The wide-angle flaps are processed from the corners of the rhinoceros African Rhinoceros bicornis or R.simus. The wide-angle flaps are often seen in the second corner or small-angle corner and are longitudinally sloping and grow into square lobes, grayish black or yellow-white. Solid and tough. The cross section of the saw is smooth and smooth, and the silk pattern is delicate and glossy. The longitudinal crack surface has a clear longitudinal straight silk pattern, and the tear burr is curled and shaped like a white hair. Gas is slightly fragrant and tasteless.
