绒毡层细胞在发育后期由单核分裂为2 核，多原位解体，为腺质型；但大约有12％小孢子囊的绒毡层在小孢子四分体释放时期进入花药室内，成为变形绒毡层。

TG-DSC results revealed that the decomposition of magnetic CoAl HTLcs proceeded in two stages. The first large endothermic effect below 220℃involves the loss of physically absorbed and interlayer water and the second endothermal effect, between 220℃and 402℃, corresponds to the decomposition of the hydroxide layers and the removal of anions in the brucite-like layers. The S_ and pore diameter information of magnetic CoAl HTLcs were tested by N_2 adsorption-desorption analysis.

TG-DSC结果表明磁性CoAl水滑石有两个过程，在220℃以下的第一个失重过程是由于物理吸附水的移除造成的，在220℃至402℃之间的主要失重过程是由于材料脱除结构水，碳酸根离子和部分羟基造成，并伴随着层板结构的塌陷。N_2 adsorption-desorption测试分析了磁性钴铝水滑石的比表面积、孔径等信息。

利用调和平均法对电缆导体外的多层介质进行处理，最终将电缆等效为导体和外护层的2层结构。

Two technology including nitrocarburizing process and salt nitrocarburzing process haver been adopted. Several conclusions were obtained: firstly, nitrided layers consist of two layers including the outer white layer, mainly ε and γ′ with favorite errosion resistance, the inner dark layer consist of α-Fe.

再往里为扩散层，扩散层与原始组织无明显区别，是过饱和含氮的α-Fe固溶体，比原始组织更易受腐蚀；(2)试样经长时间氮碳共渗后，渗层最表面会出现疏松，这是因为Fe原子向外扩散，在ε相内造成Fe原子空位，空位向内扩散，并可能在晶界上或某些晶体缺陷处堆积，以致造成空洞。

The C atom in ideal graphite crystals is hybridized in sp^2 orbital and forms covalent bonds with adjacent 3 other C atoms. The graphite crystals consist of stacks of parallel hexagonal net planar layers. These layers are integrated with Van der Waals attraction.

理想的石墨晶体是由碳原子以sp^2杂化轨道和邻近的三个碳原子形成共价键，构成六角平面的网状层片结构，层片之间以Van der Waals力相结合。
