To improve our understanding of the formation and evolution of the Moon, one of the payloads onboard the Chang＇e-3 （CE-3） rover is Lunar Penetrating Radar （LPR）. This investigation is the first attempt to explore the lunar subsurface structure by using ground penetrating radar with high resolution. We have probed the subsur- face to a depth of several hundred meters using LPR. In-orbit testing, data processing and the preliminary results are presented. These observations have revealed the con- figuration of regolith where the thickness of regolith varies from about 4 m to 6 m. In addition, one layer of lunar rock, which is about 330 m deep and might have been accumulated during the depositional hiatus of mare basalts, was detected.

Lunar Penetrating Radar （LPR） onboard the rover that is part of the Chang＇e-3 （CE-3） mission was firstly utilized to obtain in situ measurements about geological structure on the lunar surface and the thickness of the lunar regolith, which are key elements for studying the evolutional history of lunar crust. Because penetra- tion depth and resolution of LPR are related to the scientific objectives of this mission, a series of ground-based experiments using LPR was carried out, and results of the experimental data were obtained in a glacial area located in the northwest region of China. The results show that the penetration depth of the first channel antenna used for LPR is over 79 m with a resolution of 2.8 m, and that for the second channel antenna is over 50.8 m with a resolution of 17.1 cm.

通过60Co-γ射线处理籼稻品种青华占的干种子,获得一个稳定遗传的卷叶突变体(γ-rl),对其进行叶片细胞学观察、根形态特性分析及生长素(IAA)和色胺含量的分析。结果显示卷叶突变体γ-rl叶片的中脉面积比野生型增加,而侧脉数目减少;突变体种子萌发后幼苗的主根长度比野生型显著缩短,根总数也显著减少,表明幼苗期γ-rl的根系发育明显差于野生型;突变体γ-rl幼苗的主根生长对外源IAA、IAA抑制剂NPA处理的反应与野生型相比也存在显著差异;在幼苗期,突变体γ-rl叶片内源IAA的含量明显低于野生型,而色胺的含量明显高于野生型,但在抽穗期,突变体γ-rl叶片的IAA和色胺含量与野生型相比均无显著差异。研究结果将为阐明该突变体卷叶突变产生的原因及卷叶相关基因(OsFMO(t))的功能打下基础。
