Abstract
(EN)
A microbead, the periphery of the microbead being provided with an engraved code, and the microbead comprising a center area and an edge area that surrounds the center area; the peripheral profile of the edge area is non-circular both before the engraved code and after the engraved code; the edge area is provided thereon with multiple coding positions, the code of the microbead is engraved on the coding positions, and each position of the code corresponds one-to-one to each coding positions. The present invention increases the utilization rate of a microbead.
(FR)
L'invention concerne une microbille, la périphérie de la microbille présentant un code gravé, et la microbille comprenant une zone centrale et une zone de bord qui encercle la zone centrale ; le profil périphérique de la zone de bord est non circulaire à la fois avant le code gravé et après le code gravé ; la zone de bord présente sur celle-ci de multiples positions de codage, le code de la microbille est gravé sur les positions de codage, et chaque position du code correspond de façon biunivoque à chacune des positions de codage. L'invention augmente le taux d'utilisation d'une microbille.
(ZH)
一种微珠,所述微珠外围具有刻制编码,所述微珠包括中心区域与环绕中心区域的边缘区域,所述边缘区域的外围轮廓在刻制编码前和刻制编码后均为非圆形,所述边缘区域上设置多个编码位,所述微珠的编码刻制于所述编码位上,且编码的每一位与所述编码位的每一位一一对应。本发明提升了微珠的利用率。
