作者：王淑红邹应斌李小湘敖和军刘武程兆伟湖南省水稻研究所湖南长沙410125 湖南农业大学农学院湖南长沙410128

2004-2005年在长沙大田栽培条件下,以准两优527和两优293为材料,研究了低肥(N 135kg/hm2、P 29.7kg/hm2、K 112.1kg/hm2)、中肥(N 180kg/hm2、P 39.6kg/hm2、K 149.4kg/hm2)、高肥(N 225kg/hm2、P 49.5kg/hm2、K 186.8kg/hm2)对超级杂交稻产量、产量构成和某些栽培生理指标的影响。结果表明:(1)产量及有效穗数、每穗粒数、结实率等各施肥量处理间的差异不显著,但两年间的差异显著;(2)总干物质重与产量呈高度正相关,其相关系数准两优527为0.9377**,两优293为0.8630**;(3)某些栽培生理指标的品种间差异明显,其中两优293叶面积指数大、分蘖能力强,前中期干物质生产优势明显,但分蘖成穗率不高。准两优527前中期生长平稳,分蘖成穗率高,后期干物质生产优势明显,但抗倒伏能力弱。

针对某变电站35 kV主变闸刀支柱瓷绝缘子异常发热问题,通过分析加压模拟测温、直流泄漏电流检测、绝缘电阻测试和超声波检测试验的结果,初步认为支柱瓷绝缘子异常发热的原因是瓷绝缘子内部存在疏松或裂纹等结构缺陷。为此,对该瓷绝缘子进行了解剖检查和空隙性吸红试验,结果表明瓷绝缘子内部确实存在疏松(黄芯)、裂纹缺陷。最后,对该瓷绝缘子异常发热问题,提出了一系列预防措施以供借鉴和参考。

＜正＞ Wheat yellow dwarf is a serious disease of wheat infected by barley yellow dwarf virus （BYDV） .All wheat collections tested have been proven vulnerable to BYDV infection. However, Thinopyrum intermedium （ Host ）Barkworth and Dewey（syn. Agropyron intermedium （Host） P B） ,a hexaploid perennial Triticeae species （2n = 6x = 42. e1e2X = JJsSt）, contains at least two genes resistant to BYDV located on the chromosomes of group 7 and group 2, respectively. The wheat- Th. intermedium addition line LI carries the BYDV resistance gene located on the alien

Current Zoology 2019年第4期65卷 363-373页

In a study of gerbils with contrasting social and mating systems (group-living monogamous Mongolian gerbil Meriones unguiculatus, solitary nonterritorial promiscuous midday jird M. meridianus, and solitary territorial promiscuous pale gerbil Gerbillus perpallidus), we employed part ner pref ere nee tests (PPTs) to assess among-species variation in sociability and pair-bonding patterns and tested whether the nature of contact between individuals: direct contact (DC) versus nondirect contact (NDC) affected our results. We measured male pref ere nces as the time: 1) spe nt alone, 2) with familiar (partner), and 3) unfamiliar (stranger) female in the 3-chambered apparatus. Gerbil species differed strongly in sociability and male partner preferences. The time spent alone was a reliable indicator of species sociability indepe ndent of the nature of con tact, whereas the pattern and level of betwee n-species differe nces in male partner preferences depended on con tact type: DC PPTs, un like NDC-tests, discriminated well betwee n monogamous and promiscuous species. In the DC-tests, stranger-directed aggression and stranger avoidanee were observed both in the highly social monogamous M. unguiculatus and the solitary territorial promiscuous G. perpallidus, but not in the non territorial promiscuous M. meridianus. In M. unguiculatus, stranger avoidanee in the DC-tests increased the time spent with the partner, thus providing evidence of a partner preference that was not found in the NDC-tests, whereas in G. perpallidus, stran ger avoidance in creased the time spe nt alone. This first comparative experimental study of partner prefere nces in gerbils provides new in sights into the in terspecific variation in gerbil sociality and mating systems and sheds light on behavioral mechanisms un derlyi ng social fidelity and pair-b on ding.

The complexity of social-ecological systems(SeS) is rooted in the outcomes of node activities connected by network topology. Thus far, in network dynamics research, the connectivity degree(CND), indicating how many nodes are connected to a given node, has been the dominant concept. However, connectivity focuses only on network topology, neglecting the crucial relation to node activities, and thereby leaving system outcomes largely unexplained. Inspired by the phenomenon of ‘‘consensus of wills and coordination of activities' ' often observed in disaster risk management, we propose a new concept of network characteristic, the consilience degree(CSD),aiming to measure the way in which network topology and node activities together contribute to system outcomes. The CSD captures the fact that nodes may assume different states that make their activities more or less *** two nodes with in/compatible states will lead to outcomes that are un/desirable from the perspective of the SeS in question. We mathematically prove that the CSD is a generalized CND, and the CND is a special case of CSD. As a general, fundamental concept, the CSD can facilitate the development of a new framework of network properties, models, and theories that allows us to understand patterns of network behavior that cannot be explained in terms of connectivity alone. We further demonstrate that a co-evolutionary mechanism can naturally improve the CSD. Given the generality of co-evolution in SeS, we argue that the CSD is an inherent attribute rather than an artificial concept, which underpins the fundamental importance of the CSD to the study of SeS.
