As a result, if the iridescence is produced by thin-film interference, not only the thickness of lamellar structure must be defined within a certain nanometer, but also the refractive index need to be different between lamellar structure. In other words, the chemical composition, refractive index and thickness of exsolution lamellae need form to trinity, such as labradorite, albite, andradite and orthoamphibole. If the iridescent color is produced by grating-diffraction, the lamellar structure just needs to be arrayed regularly, the spacing of the edges of lamellar structure needs to be regular and narrow, but not necessarily within the range of the wavelength of visible light, such as shell of abalone, pearl and opal.

薄膜干涉式晕彩不仅要求宝石内部结构层的厚度必须在一定的纳米范围内，而且结构层内部的折射率也必须有所差别，也即，当结构层由两相组分出溶而成，其化学成分、折射率和结构层厚度形成三位一体时，符合薄膜干涉式晕彩，如拉长石、钠长石、石榴石和角闪石；而光栅式衍射晕彩则仅要求结构层排列规则，边缘狭窄但不需要窄到可见光波长范围内，能使入射光的振幅或位相，或两者同时产生周期性空间调制的结构即可，如鲍贝壳、珍珠和欧泊。

The pore distribution in the direction of coating thickness was self-existent and could not join to intercommunicating pore.The pore diameter was very tiny so that it could prevent hydrotropic solution entering into the pore.

机械镀锌的形层过程既没有热镀锌那样的高温冶金反应，也没有电镀锌那样的电沉积效应，镀层是常温常压下利用化学吸附沉积和机械碰撞使金属锌粉在工件表面镶嵌堆积而成[1]，所以人们认为机械镀锌镀层的致密性要低于电镀和热镀锌镀层，但机械镀锌镀层又表现出良好的耐腐蚀性能。

The phase structure of the ceramic-coating includes γ-Al2O3, AlPO4 and CoO. The forming process of the ceramic-coating includes iron movement, melting of surface layer, movement of electrolyte towards the melting-zone and the final nucleus-forming and sintering.

Based on the results, it has found that six distinct layers can be identified from lateral to medial in the olfactory bulbs, and the adults have more cells than the subadults. Ventricles of the adults take up larger vacuity, have richer choroids plexus, and primordial pallium and primordial hippocampus of them are more developed than the subadults, in which the primordial piriform is well-developed. Ventral to the primordial hippocampus, there is a septal area which can not be divided into medial and lateral parts in both adults and subadults, nor there is lateral limiting sulcus to separate the primordial piriform and the corpus striatum, but only in the subadults, a medial limiting sulcus can be clearly identified to separate the primordial hippocampus and the septal area. Besides, the corpus striatum of Onychodactylus fischeri is paleostriatum. The cell group that located at two sides of the third ventricle is amygdale, and shape and size of neurons within the telencephalon are poorly differentiation.

结果表明：爪鲵嗅球内细胞从外到内大致可分为6层结构，亚成体的细胞数量少于成体；成体爪鲵的侧脑室所占空间较大，脉络丛更为丰富，原始大脑皮层和原始海马都比亚成体发达，后者大脑内原始梨状区较为发达；隔区位于原始海马的下方，成体和亚成体都没有外侧隔核和内侧隔核之分，也没有外侧界沟作为原始梨状区和纹状体的分界，而在亚成体的侧脑室壁有内侧界沟区分原始海马和隔区，成体则没有；此外，爪鲵的纹状体属于古纹状体，杏仁核是位于第三脑室两侧的两个细胞团，端脑内细胞形态和大小分化较为单一。

The medium-grained sandstones and medium-fine-grained sandstones form good reservoirs and the poststones medium reservoirs, while siltstones form poor reservoirs and pelitic siltstones poorest reservoirs. Sand bodies mostly develop in sand-flats, tidal channels and distributary channels of braided stream delta microfacies. The reservoir rocks of sand-flat and tidal channel are best with the physical property. Diagenesis such as compaction, cementation and dissolution has strongly reformed the reservoir rocks and the late dissolution has greatly improved their porosity and permeability.

中粒砂岩、中细粒砂岩属好储层，细粒砂岩属中等储层，粉细砂岩，粉砂岩属较差储层，而泥质粉砂岩则属差储层；砂坪、潮道和辫状河三角洲分流河道微相中的砂体最发育，它们决定了储集岩的发育、分布及原始物性条件；砂坪和潮道储集岩的物性最好，辫状河三角洲分流河道储集岩的物性次之，砂泥混合坪、辫状河三角洲分流河道间储集岩的物性较差；成岩作用对本区CⅠ油组的储层有强烈的改造作用，尤其是较晚期的溶蚀作用对岩石的储集性能有明显的改善，对本区CⅠ油组中孔高渗透储层的形成有很大的贡献。

碳纳米管／镍基激光熔覆层耐腐蚀的原因在于熔覆层保留的碳纳米管使熔覆层更加致密，隔离了腐蚀介质，促进了镍基合金的钝化，从而提高了熔覆层的耐蚀性；同时，熔覆层中保留下来的碳纳米管和被分解的碳纳米管与金属基体形成碳化物，作为增强相均匀弥散在熔覆层中，它们的存在阻止了腐蚀坑的长大，因而蚀坑较小，耐腐蚀性得到提高。
