In this study, copper alloy adding Ti-Zr and Al-Zr was the target and made the cupper alloy ingots by vacuum arc remelter. After rolling and heat treatment, the two-inch round target was cut by wire electrical discharge machining. DC sputtering deposited cupper alloy thin films on silicon base materials and optical glasses to discuss the thin film microstructures、compositions、practical performances and optical characteristics.

中文摘要本研究以自行设计之铜基合金靶材，在铜基材料中添加钛锆与铝锆等微量金属，以真空电弧熔炼制作铜合金方锭，经滚压加工及热处理后，以线切割机切成两吋之圆型靶材，再进行直流溅镀沉积铜合金薄膜於矽基板和光学玻璃基板上，探讨不同成分比例下之薄膜显微结构、成分组织、实用性能与光学特性。

The system point spread function is designed to be similar to the Dirac delta function. The experimental results and the theoretical calculation of the PSF are in accordance. The experiments on absorbers embedded in the intralipid solution with concentration of 1% and depth of 1.7 cm are implemented.

用菲涅耳波带板扫描全息成像系统进行了成像实验，得到了嵌埋在浓度为1%、深度为1.7 cm的脂肪乳剂中的吸收体清晰的再现像，吸收体为直径0.4 mm的金属丝和内径为6.0 mm的金属环，另外，也得到了直径为2.5 mm的黑塑料球的再现像。

Electron emission characteristics have been investigated for amorphous diamond films with low or even negative electron affinity.

摘要利用阴极电弧法分别在矽基板及镀有一层钐金属的矽基板上沉积非晶钻石。

It didn't have metal frets, but the fingerboard was scalloped so the tips of each scallop were the frets.
