摘要：等离子平面显示(pdp)用荧光粉的主要参数有发射光谱,色坐标,激发光谱,相对亮度等。由于pdp荧光粉的激发光源在紫外 真空紫外波段,因此需要一套真空紫外激发 荧光光谱仪装置来测量这些参数。介绍了一种采用30W氘灯激发光源的pdp粉体测试装置。通过光路的聚焦式设计和高增益放大器的采用,实现了120～300nm波段,分辨率好于2nm的激发光谱测量。测试结果表明发射光谱和激发光谱的重复性好于±2%,色坐标误差小于±0.001。

摘要：This study focused on differences in vehicle-to-vehicle radio channel character- istics in the same region but different traffic density and speeds at 5.9 GHz （congestion and non-congestion）. The continuous measurement campaign was conducted on a city expressway through the complex dense urban area in Wu- hart, China. Small-scale channel characteris- tics including power delay profile, amplitude fading distribution, K-factor, delay spread and Doppler shift were obtained, respectively. Spe- cifically, the cumulative distribution function of root mean square delay spreads and root mean square Doppler spreads in the non-con- gested scenario and congested scenario were all fitted well with Lognormal distribution. We also found out that different intensity of traffic and speed of vehicles have little effect on root mean square delay spreads, but have a big im- pact on root mean square Doppler spreads and level crossing rate. According to estimation outcomes, the V2V channel characteristics for urban areas in Chinese big city were differ- ent from the previous measured results under similar scenarios in Europe. Delay spread and level crossing rate in this study can provide significant references to design the wireless communication system for vehicle-to-vehicle channel.
