亮度

Generally, this is a limiting factor for luminance, the higher the aperture ratio, the brighter the luminance.

通常，这是亮度的一个限制的原素，孔比率越高，亮度越明亮。

Another approach in enhancing the light extraction efficiency of AlGaInP LED was accomplished using a surface roughening process. In this process, the Au(170 nm)/AuBe(260 nm)/Au(170 nm) ohmic contact layers were first deposited on the GaP window layer. After the alloy annealing process (480°C for 10 min), the Be atoms will diffuse into the GaP top layer and form non-uniform clusters. The LED samples were then immersed into a mixture 3H3PO4:1H2O2:1H2O solution for 6 min, resulting in a rough GaP surface. The luminous intensity of the AlGaInP LED can increase from 42 to 50 mcd, that is, an 18% enhancement can be achieved via the present non-photolithography surface roughening process.Keywords: LED, AlGaInP, Cu substrate, Reflector, Surface roughening

在实验的第二部份是开发磷化镓窗口层之粗化制程，我们是藉由正面金/铍欧姆接触电极之熔合制程，使铍扩散至磷化镓层，同时利用铍渗入磷化镓造成之特殊组成，可形成不均匀之蚀刻阻挡，而在磷化镓表面形成粗化，我们发现480℃、10分钟的熔合制程，加上浸泡磷化镓蚀刻溶液6分钟，可将四元发光二极体之发光亮度由42 mcd 提升到50 mcd，经由此无光罩粗化制程可将亮度提升18%，明显提升磷化铝铟镓发光二极体之外部量子效率。

Primers used in PCR were designed based on the sequence of mitochondrial 16S rDNA (AJ250642 and AF312718) and beta-actin (AY910691) of Eriocheir sinensis which had been deposited in GenBank. PCR analysis using total DNA from muscle, branchia, testis and sperm indicated that 16S rDNA exhibited different expression in the four samples. Beta-actin gene was detected plentiful in all the four tissues/cells and exhibited the same expression pattern. 16S rDNA gene amplification was detected at high levels in muscle and branchia, appreciable low in testis and very low in sperm. The PCR products of 16S rDNA gene were sequenced and aligned with the sequence of 16S rDNA from GenBank (AJ250642 and AF3 12718), and the alignment result showed there was no difference between them.

通过GenBank中的中华绒鳌蟹线粒体16S rDNA序列设计引物，利用PCR扩增方法，以beta-actin做内参，检测了中华绒螯蟹肌肉、鳃、精巢和精子中线粒体16S rDNA扩增情况，发现各组织或细胞beta-actin扩增片段大小、条带宽度和亮度基本一致，表明各模板DNA量基本一致；而在同一DNA浓度下，16S rDNA的扩增片段长度虽一致，但其产物量存在明显差异，精子16s rDNA产物量显著低于其他3种组织，其条带宽度和亮度很弱；16S rDNA扩增产物经测序分析及比对证明与已有序列完全吻合。
