Based on the results of DEA model, we dissected scale advantages of each discretionary scheme or plan. We examined scale advantages of each discretionary scheme, tested profoundly a definitive purpose behind not-DEA efficient, which elucidated the system and methodology to enhance these discretionary plans. At the end, another method had been proposed to rank and select the optimal scheme. The research was important to guide the practice if the modification of agricultural production industrial structure was carded on.展开更多

Later on, the Chang'E-2 and Chang'E-3 satellites were successfully launched in 2010 and 2013, respectively. In order to achieve the science objectives, various payloads boarded the spacecraft. The scientific data from these instruments were received by Beijing and Kunming ground stations simultaneously. Up to now, about 5.628 Terabytes of raw data were received totally. A series of research results has been achieved. This paper presents a brief introduction to the main scientific results and latest progress from Chang'E-3 mission.展开更多

There were T.citrinoviride, T.longibrachiatum, T.sinensis in section Long ibrachiatum, T.atroviride, T.koningii, T.viride, T.asperellum, T.hamatum, T.e rinaceum in section Trichoderma, T.harzianum (H.lixii), T.inhamatum, T. ve lutinum, T.cerinum, T.strictipile, T.spirale, T.virens, H.nigrovirens (Trichode r ma sp.) in section Pachybasium. Among them four species: T. asperellum, T .velutinum, T.cerinum, T. spirale were reported firstly in China. In addition, two suspected new taxa (Trichoderma spp.) in Trichoderma s ec tion were proposed: Trichoderma sp.1 (ZAUT261, 4, 4A, 15A, 2C), Trich od erma sp.2 (2B, 5, 7A, 7B, 9A). Trichoderma sp.1 was similar to T.h a matum , but the temperature optimum for mycelial growth was lower than that of T.hamatum and the species tended to form hemisphaerical pustule with rela tively larger conidia (average length 4.6 μm×2.8 μm). Trichoderma sp.2 was distinguished morphologically from related species T. strigosum, T. pub escens, T. erinaceum, T. hamatum and Trichoderma sp.1 in pustules on CM D without fertile or sterile conidiophore elongation and distinctive phialide sh ape, the conidiophore branches similar to T.koningii, but the conidia sim ilar to T. viride, subglobose, conspicuously tuberculate.展开更多
