Finally, after these nodes are connected according to the certain rule, the quadrilateral grid of tooth profile plane model is generated.

先按照齿廓的形状，在齿廓平面模型的不同部分生成一定疏密间隔的控制线，然后在控制线上生成一定疏密间隔的节点，最后根据一定的规则连接这些节点，即可自动生成齿廓平面模型的四边形网格。

Following the puncture of zona pellucida with two holes by injection pipette that contained donor nuclei or cells, the injection pipette was pulled back to the perivitelline space while the negative pressure was increased in the holding pipette until the polar body and karyoplasm were wiped off completely. Then a reconstructed embryo was completed by the direct injection of the donor nucleus or cell without pulling out the injection pipette.

首先以预先吸有细胞核或细胞的注射针在固定于持卵针上的卵母细胞透明带上穿刺两个孔，然后一边缓慢地将注射针回拔至卵周隙中，一边逐渐增加持卵针中的负压，直至极体与目标核质被完整吸入持卵针中而完成去核，最后在不拔出注射针的情况下直接注射细胞核或完整细胞进而完成重构胚的构建。
