The typical structural characteristics of oil cells include, presence of a tripartite cell wall, in which the outer and inner layers are cellulose, the middle layer is a suberin layer lamellated; presence of a cupule attaching the oil vacuole to the wall; presence of plasmodesmata occurring in wall protuberances, which is coursed by the suberin layer.

成熟油细胞结构的典型特征是：具有三层暗明暗相间的细胞壁，内外两层是纤维素壁层，电子不透明，中间一层是电子透明的木栓质化壁层，由明暗相间的片层结构组成；细胞腔被油囊充满，它由一个细胞壁向内突起的杯形构造连接于细胞壁上：胞间连丝发生于由木栓质化壁层形成的一个向内的突起中。

In Chapter 3, for a prime p as 6κ+1, we represent the finite field of order p as a sublattice of Eisenstein integers concretely.

Based upon this, the author puts forward that the supercooling solidification should consist three stages, i.

据此，提出深过冷凝固过程应包含形核、快速再辉和快速凝固三个阶段。

Two component design total ankle replacement is based on restricted type design to prevent dislocation ,and make syndesmosis union to enlarge tibia component contact area and stability. Three component design total ankle replacement is based on unrestricted type design. Components are mimic to anatomic shape ,and congruent polyethylene insert was also characterized. Successful total ankle replacement depends on reasonable prosthesis design and rational contact stress .

二件式人工踝关节，其设计理念，在於以高限制型设计，避免脱位之产生，并以胫骨腓骨骨联合扩大胫骨元件的接触面积与稳定度；三件式人工踝关节，主张以非限制型设计，近於解剖形状之元件，以及与关节面一致构形的聚乙烯内衬为其特点成功的全踝人工关节置换术仰赖合理的踝关节设计以及合理的接触压力。
