后生韧皮部

There is no transition between root and epicotyl of dicotyledonous seedlings with epigeal germination, whereas only having a directly simple connection between the tissues with the same radially developmental direction.

真叶叶迹的木质部与下胚轴中靠近韧皮部的后生木质部或次生木质部连接。根与上胚轴之间不存在维管组织的过渡、转变，而只是在同样发育方向的组织中有一种直接的简单的连接

It consists of the PROTOPHLOEM and METAPHLOEM.

由原生韧皮部和后生韧皮部组成。

The PROTOPHLOEM and METAPHLOEM are primary tissues and derived from the procambium,while the secondary phloem is formed from the VASCULAR CAMBIUM.

原生韧皮部和后生韧皮部属于初生组织，来源于原形成层，而次生韧皮部由维管形成层产生。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
