The original version of this Article contained errors in the second sentence in the legend of Fig. 1, which incorrectly read 'These two elastic insulators are identical in lattice constant a (3a), plate thickness (0.4a), and radius of perforated holes r (0.18a) but different hole-center distance characterized by b.' The correct version states 'plate thickness (√3 × 0.4a)' in place of 'plate thickness (0.4a)' and 'radius of perforated holes r (√3 × 0.18a)' rather than 'radius of perforated holes r (0.18a)'.The first sentence of the 'Sample preparation' section of the Methods originally incorrectly read 'Our samples are prepared exclusively on polished stainless-steel plates (Type 201, mass density 7803 kg m) with a fixed plate thickness 7.82 mm.' In the corrected version, 'mass density 7903 kg m' replaces 'mass density 7803 kg m'.The second sentence in the legend of Supplementary Fig. 3, originally incorrectly read 'The symmetry of the phononic crystal remains unchanged as C, and thickness of the substrates H (equals to 0.4a), lattice constant a (equals to 3a) and radius of perforated holes r (equals to 0.18 a) maintain constant.' The correct version states '√3 × 0.4a' in place of '0.4a' and '√3 × 0.18a' rather than '0.18a'.This has been corrected in both the PDF and HTML versions of the Article.
本文的原始版本在图1的图例第二句中存在错误,原句错误地表述为“这两个弹性绝缘体在晶格常数a(3a)、板厚(0.4a)和穿孔半径r(0.18a)方面相同,但孔中心距不同,用b表示”。正确的版本将“板厚(0.4a)”表述为“板厚(√3 × 0.4a)”,将“穿孔半径r(0.18a)”表述为“穿孔半径r(√3 × 0.18a)”。方法部分“样品制备”一节的第一句原错误表述为“我们的样品仅在抛光的不锈钢板(201型,质量密度7803 kg m)上制备,板厚固定为7.82 mm”。在修正版本中,“质量密度7903 kg m”取代了“质量密度7803 kg m”。补充图3的图例第二句原错误表述为“随着C的变化,声子晶体的对称性保持不变,并且衬底的厚度H(等于0.4a)、晶格常数a(等于3a)和穿孔半径r(等于0.18a)保持恒定”。正确的版本将“0.4a”表述为“√3 × 0.4a”,将“0.18a”表述为“√3 × 0.18a”。本文的PDF和HTML版本均已进行了修正。
