Methods: We divide the rats into 5 groups in random, with Morris method, detect the change of some active oxygen radicals such as super-oxide demitasse, Nitric Oxide Synthase, malondialdehyde etc. Also, we detect the change of cholinesterase, Monoamine Oxidize; using HE,PAS staining, immuno-histochemical technique, detect hippocampus CA1 cerebral pathology slices optical density value of NOS, CHE and lipofuscin of neural cell; detecting apoptosis rate and the expression of P53 , which are neuronal apoptosis related genes.

大鼠随机分为5组，采用"Morris水迷宫"法观察脑缺血性模型大鼠学习记忆功能，检测超氧化物歧化酶、一氧化氮合酶、丙二醛等自由基代谢异常的改变，检测胆碱酯酶、单胺氧化酶等老化相关酶的变化、脑组织神经细胞免疫组织化学技术、检查海马CA1区脑组织的病理切片，检测NOS、CHE光密度值；流式细胞技术：检测细胞凋亡率，及促细胞凋亡基因、P_(53)蛋白表达；病理切片采用HE染色、PAS染色及免疫组化法检查，检测对大鼠海马神经元细胞一般病理变化及脑细胞内脂褐含量。

Thermal oxidation treatment can increase the surface hardness and elastic modulus significantly and reduce the E /H ratio of the TC4, which indicate the treatment can enhance the wear resistance of TC4 alloy. Long time treatment can increase the thickness of the oxide layer, but the outside layer is apt to desquamate during the scratching. The oxide layer closing to substrate has better bonding properties, but microcrack forms as a result of high stress loading, which lead the layer to flake off completely.

长时间的高温氧化可以增加氧化层的厚度，但在划擦过程中氧化层发生两次脱落，表明氧化层由外表层和次外层组成，外层结合力差，易发生一次脆性剥落，内层与基体的结合强度较高，但在较大载荷作用下会产生微裂纹，导致氧化层的二次剥落。

And the emission band at 420 nm should be contributed to intrinsic diamagnetic defect in the amorphous oxide layer, while the damaged oxide layer could contribute to the bands around 420 nm.

通过真空退火之后发现470nm的谱峰明显变强了，这一实验结果证实了此峰是由纳米硅线表面氧化层的氧缺失缺陷引起的说法。
