This paper deals with the Zonophyllids collected from the Longdongshui Forma-tion of the Early Middle Devonian(Eifelian)in Dushan of southern Guizhou.Through studying the ontogeny and the phylogeny of Zonophyllids,the writer suggeststhat the Zonophyllids are most probably derived from the Silurian Pycnactis.In theZonophyllids,fine structure of the septum is of the monacanthine;and the majorsecondary septa are developed on both sides of the counter septum(Yü-type).Thus,the Zonophyllids quite different from the...

This paper deals with the Zonophyllids collected from the Longdongshui Forma-tion of the Early Middle Devonian(Eifelian)in Dushan of southern Guizhou.Through studying the ontogeny and the phylogeny of Zonophyllids,the writer suggeststhat the Zonophyllids are most probably derived from the Silurian Pycnactis.In theZonophyllids,fine structure of the septum is of the monacanthine;and the majorsecondary septa are developed on both sides of the counter septum(Yü-type).Thus,the Zonophyllids quite different from the Silurian Cystiphyllids should be referred tothe Mesocorallia Yü,1963.According to the above mentioned statement,the writer isinclined to revise the classification of“Cystiphyllids”as follows:Cystiphyllida Nicholson,1889Tryplasmatidae Etheridge,1907Cystiphyllidae Edwards et Haime,1850Goniophyllidae Dybowski,1873Mesocorallia Yu,1963Zonophyllidae Wedekind,1924Zonophyllinae Wedekind,1924Digonophyllinae Wedekind,1923Arcophyllinae Markov,1926Cystophrentidae Yu,1963Pycnactidae Hill,1940

This paper deals with the tabulate corals and chaetetids collected from the Long-dongshui Member of the Houershan Formation in Dushan of Guizhou.The collec-tions contain 19 genera and 50 species(including 12 new species and 3 varieties)oftabulate corals,2 genera and 2 species of heliolitids and 2 genera and 4 species(in-cluding 2 new species)of chaetetids.The new species are:Roemerolites dushanensis(sp.nov.),R.Polymorphus(sp.nov.),Parastriatopora jumuwanensis(sp.nov.),P.jumuwanensis var.varia(var.nov.),P.jumuwanensis var.thamnoporoidea(var.nov.),Thamnopora tersa(sp.nov.),T.longdongshuiensis(sp.nov.),Gracilopora spina(sp.nov.),Alveolites convolutus(sp.nov.),A.inconstans(sp.nov.),Crassialveolites yun-nanensis var.dushanensis(var.nov.),Caliapora mixta(sp.nov.),Placocoenites elas-matus(sp.nov.),Aulopora mixta(sp.nov..),Syringoporella convexotabulata(sp.nov.),Chaetetes raritabulatus(sp.nov.)and Cyclochaetetes distortus(sp.nov.).Thetabulate corals,heliolitids and chaetetids were found together with rugose corals(Utaratuia sinensis,Sociophyllum minor and Breviseptophyllum kochanensis etc.)andBrachiopods(Acrospirifer houershanensis,Eospiriferina lachrymosa,Athyrinsinasquameosaeformis,Acrospirifer fongi,Gypidula biplicata and Kwangsia perfecta etc.).Accordingly,the tabulate coral-bearing deposits may be assignable to the early MiddleDevonian stage,approximately corresponding to the Eifelian stage in Europe.Basedupon the characteristic features of the tabulate corals and chaetetids,two coral assem-blages may be recognized in the Longdongshui Member of the Houershan Formation,the upper assemblage is characterized by the presence of Parastriatopora jumuwanen-sis,Favosites clarus and Roemerolites dushanensis,while the lower assemblage isrepresented by Pachyfavosites nilella,Favosites multiplicatus and Pachycanalicula bar-randei.

本文记述了黔南独山中泥盆世早期的猴儿山组龙洞水段中的15个床板珊瑚新种及新变种和2个刺毛虫类的新种。通过对床板珊瑚、日射珊瑚和刺毛虫类组合的分析,确定龙洞水段的地质时代为中泥盆世早期。根据床板珊瑚在地层上分布的规律,又可以将它划分成上部的Parastriatopora jumuwanensis-Favosites clarus-Roemerolites dushanensis 组合和下部的Pachyfavo-sites nitella-Favosites multiplicatus-Pachycanalicula barrandei 组合。

This paper introduces a two-dimensional laser Doppler velocimeter ap--plied to measurements of flow field in water-tunel and water-model. In this device, He-Ne laser is used as a light source and a rotating circular grating is used as both the light spliter and the optical frequency shifter. Therefore, it is simple, cheap and valuable for wide applications.
