Result :We found that the line from the apes of the mastoid process making for the front margin 4cm(superior 1/4 joint with inferior 3/4)of the sternocleidomastoid muscle to the posterior margin 5cm(superior 1/3 joint with inferior 2/3)is the projective line of the accessory nerve(80%±5%).

结果：见乳突尖向胸锁乳突肌前缘4cm（上1/4下3/4交点）和向下至后缘5cm（上中1/3交点）处连线深面有副神经（80%±5%），该处是切断胸锁乳突肌及其副神经肌支的最佳部位之一。

In the leaves of Liriodendroideae, some of the abaxial epidermal cells are papillose and the vascular tissue of the main vein appears to be separated. However, papillose were not found and there are uniseriate, multicellular or unicellular hairs distributed on the epidermis, and the vascular tissue of the main vein appears to be continuous in the leaves of Magnolioideae. Furthermore, in the Magnolioideae, the structure of the leaves of plants in Manglietia are different from that of Magnolia.

结果表明：鹅掌楸亚科和木兰亚科在叶的结构上的主要区别是鹅掌楸亚科两种植物叶的部分下表皮细胞呈乳突状，且整个细胞外壁只形成一个乳突，而在木兰亚科的植物中有单列多细胞或单细胞的表皮毛，未发现乳突；鹅掌楸亚科植物的叶主脉维管组织环分隔呈束状，且其外包被的纤维也排列成束状，而木兰亚科的80种1亚种植物中，叶主脉维管组织连成轮状，其外面也由一圈连续的纤维环所包围。

The supramastoid crest and the superior rim of zygoma arch correlated with the level of the bottom of the middle fossa.
