On this basis, a kind of symmetry bevel automatic welding equipment with vertical and horizontal tracking system is designed, which has met the production requirement well. 在此基礎上設計并研制了具有高度和橫向跟蹤的兩側對稱(chēng)斜角自動(dòng)焊設備，較好地滿(mǎn)足了生產(chǎn)需求。
The graph is divided by its symmetry axis. 這個(gè)圖形沿著(zhù)對稱(chēng)軸左右對稱(chēng)。
Bilateral symmetry, for example, is almost universal among animals. 舉例來(lái)說(shuō)左右對稱(chēng)就幾乎普遍地存在動(dòng)物世界。
