The aluminum-air battery is considered to be an attractive candidate as a power source for electric vehicles(EVs) because of its high theoretical energy density(8100 Wh kg^(-1)), which is significantly greater than that of the state-of-the-art lithium-ion batteries(LIBs). However,some technical and scientific problems preventing the large-scale development of Al-air batteries have not yet to be resolved. In this review, we present the fundamentals, challenges and the recent advances in Al-air battery technology from aluminum anode, air cathode and electrocatalysts to electrolytes and inhibitors. Firstly, the alloying of aluminum with transition metal elements is reviewed and shown to reduce the selfcorrosion of Al and improve battery performance. Additionally for the cathode, extensive studies of electrocatalytic materials for oxygen reduction/evolution including Pt and Pt alloys, nonprecious metal catalysts, and carbonaceous materials at the air cathode are ***, for the electrolyte, the application of aqueous and nonaqueous electrolytes in Al-air batteries are discussed. Meanwhile, the addition of inhibitors to the electrolyte to enhance electrochemical performance is also explored. Finally, the challenges and future research directions are proposed for the further development of Al-air batteries.

During the 3rd mission of Chinese Unmanned Spacecraft the application sys tem of "SZ-3" (Shenzhou, a divine ship) gets a great success, all its goals are achieved. Many areas of science and breakthrough technology, including earth observation, earth environment monitoring, space material, space life science etc., are carried out in the mission. There are 44 payload instruments *** the instruments are working well during the orbit flight and a lot of good results are obtained. Many areas, for example the moderate resolution imag ing spectroradiometer, the solar ultraviolet spectral irradiance monitor and the space protein crystallization facility perform better than required and expected.A brief introduction of the experiments and the achievements of the mission is given in this paper.

在我还是外科住院医师的时候,林顿、布莱克莫尔、德巴基等人对临床上各种血管手术的报道对我产生了很大的影响。随后我决定找一些有腹水的狗,以便于我同时研究狗和肝硬化患者的腹水。匹兹堡市圣弗朗西斯医院的玛丽·阿黛尔护士长,是个非常友善的人,一次就买了3只狗,并将它们伺养在病理学实验室大楼的屋顶上。单纯地通过胸腔下静脉缩窄术所获得的犬腹水中蛋白质含量远高于肝硬化患者。腹水形成后6个月,将腹直肌一端切断,进行腹膜转位,这样腹水便可以流经肌纤维。我在匹兹堡大学外科住院医师科研大会上发表这篇论文时,第一次见到了匹兹堡大学外科研究实验室的负责人伯纳德·费舍尔医生。当我在1955年完成了圣弗朗西斯医院的住院医师实习时,他邀请我加入他的团队。
