基于系统工程的系统分类法及应用 总被引:2,自引:0,他引:2
首先叙述了一般文献中对系统的分类,然后对钱学森为首的一批知名学者关于系统的人和了介绍。详细地讨论了Shenhar和Bonen对系统的二维分类法,并同钱学森的系统分类法进行联系,根据2-D分类法,提出了系统开发的三维结构,最后对其应用实例进行了说明。 相似文献

A new giant cave-dwelling species of planthopper of the family Meenoplidae (Fulgoromorpha) is described from the Tsingy de Bemaraha National Park in western Madagascar, with information on its distribution and ecology. As the new species could not be placed in any of the previously described genera, a new genus is established. This is the first record of a cavernicolous meenoplid from the Afrotropical Region, and the second cave-dwelling Fulgoromorphan species from Madagascar. It is also the second example of island gigantism in the Fulgoromorpha from Madagascar. 相似文献

The ground plan of the bot flies (Oestridae, part) is compared with those of Ephydroidea and Calyptratae. Comparative anatomy suggests that the bot flies are unlikely to have arisen from within Calyptratae and that their derivation from near the base of Ephydroidea is more probable. A large body of evidence is assembled to counter the theory that would place Oestridae within the Tachinidae family-group. It is shown that Hippoboscoidea is unlikely to be monophyletic. The fit of Glossinidae to the suggested ground plan profile of the Ephydroidea/bot flies is shown to be good. 相似文献

Increasing oil-exploration activity and associated ecological surveying west of the Shetlands is leading to the discovery of many poorly known or undescribed tanaidaceans. Three species of the typhlotanaid genus Paratyphlotanais Kudinova-Pasternak and Pasternak, 1978 have been recorded from shelf and bathyal depths between Iceland, the Faroe Islands and the western margin of the British Isles. Two, P. gracilipes (Hansen) and P. microcheles (G. O. Sars), formerly belonging to the genus Typhlotanais, are redescribed and a new species is described. A key to their identification is included. Inhabiting largely discrete zoogeographic areas, these species help define regional macrofaunal associations. 相似文献

Three new eriophyoid mite species (Acari: Eriophyoidea: Eriophyidae) from China are described and illustrated. They are Cecidophyes truncatis sp. nov. on Acer truncatum Bunge (Aceraceae), Cecidophyes hirsutes sp. nov. on Cardamine hirsute L. (Cruciferae) and Paracolomerus fopingacer sp. nov. on Acer sp. L. (Aceraceae). All the new species described herein are vagrants on the host plant. 相似文献

Thirteen Notostrix Keifer species are presently known, all from leaves of palm trees (Arecaceae) to which they seemingly cause no major damage. A new species of this genus, Notostrix macrothrix sp. nov., is morphologically described based on adult females and males collected from coconut, Cocos nucifera L. (Arecaceae), on La Reunión Island. A discussion about the presently known distribution of mites of this genus is also presented. http://www.zoobank.org/urn:lsid:zoobank.org:pub:14C65CB2-AF56-4D85-AD49-56FA11119EF5 相似文献

本文对水狼蛛属Genus Pirata的几种蜘蛛进行了修订研究。通过对雌性生殖■、雄性触肢中突及生殖球顶部的比较研究,认为:秦岭水狼蛛Pirata qinlingensis Zheng et Qiu,1980为八氏水狼蛛P.yaginumai Tanaka,1974新的同物异名;弓水狼蛛Pirata praedatoria Schenkel,1953、武昌水狼蛛Pirata wuchangensis Schenkel,1963同为类水狼蛛P.Piratoides(Bos.etStr,1906)的新的同物异名;中华水狼蛛Pirata procuruus sinensis Song et al,1978(近来有人将其上升为种)、加拿大水狼蛛P.canadensis Dondale et Redner,1981二者均为前凹水狼蛛P.procuruus(Bos.et Str,1906)新的同物异名。另外比较了易混淆的真水狼蛛和拟水狼蛛,重新描述了克氏水狼蛛;对水狼蛛属的主要特点和分类学价值也进行了系统的讨论。 相似文献
