The refractive index of metal effects mainly resonance depth and the half peak breadth. There is an optimum metal thickness with the largest resonance depth and the smallest reflection coefficient. The refractive index and thickness of dielectric layer and recording layer impact resonance angle and the half peak breadth.

金属薄膜的折射率是影响共振半峰宽度和共振深度的主要因素，计算表明存在一个最佳的金属层厚度，使得共振深度最大，反射系数最小；介质层和记录层的折射率和厚度的变化均会影响共振角的大小和共振峰半峰宽的变化。

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。

In this thesis, the AlN thin films were deposited on SiO2/Si and GaN/Sapphire substrates respectively for layered structure SAW devices by Helicon sputtering system. Laser ultrasound system was used to measure the acoustic wave velocity of AlN/SiO2/Si layered structure. Frequency response and insertion loss were measured by an HP8510C vector network analyzer to analysis insertion loss, sidelobe and quality factor. The results showed the possibility of incorporating thin films SAW devices with other semiconductor devices.
