[目的]满足粮农对高产、优质、广适和多抗玉米新品种的需求,使粮食持续增产。[方法]2015年通过不同海拔地区玉米新品种田间对比试验,对玉米产量、主要经济性状、主要农艺性状、生育期和抗逆性等指标进行分析。[结果]芮单26和永瑞16可以在海拔2 200 m以下地区推广种植;华兴单88可以在海拔1 750 m以下地区推广种植,其他品种需进一步试验。[结论]该研究结果可在该地区和其他类似地区推广应用,将有效促进玉米品种更新换代,提高单位面积产量。
[Objective] To meet the needs of grain farmers for new varieties of high yield, high quality, wide adaptability and multi-resistance so that the grain output will continue to increase. [Method] The maize yield, major economic traits, major agronomic traits, growth period and stress resistance were analyzed in field trials of new maize varieties at different altitudes in 2015. [Result] Ruidan 26 and Yongrui 16 could be planted in the area below 2,200 m. Huaxing 88 could be planted in the area below 1,750 m. The other varieties needed further tests. [Conclusion] The results of this study can be popularized and applied in this area and other similar areas, which will effectively promote the upgrading of maize varieties and increase the yield per unit area.

针对激光雷达回波信号所含噪声的特点,对比分析了传统去噪算法的优缺点,重点就小波自适应阈值去噪方法和独立成分分析去噪方法进行了系统研究。为了验证这两种方法在激光云高测量信号去噪上的有效性和优劣性,对包含高斯白噪声的模拟仿真信号进行了消噪,并对半导体激光云高仪实际探测得到的大气回波信号进行了消噪处理,最后对去噪结果进行了对比分析。仿真结果和实验结果表明,这两种消噪方法均能够有效降低激光雷达回波信号中所
