煤矿用带式输送机跑偏原因分析及预防措施

在生产中出现输送带跑偏引起其边缘与其他部件剧烈摩擦,致使输送带的边缘被磨损,甚至撕边及物料撒落。因此,增加了大量的人力投入,成为带式输送机使用中的一大痼疾。为解决这一问题,笔者针对同煤集团使用的各种型号带式输送机进行实地观察、分析、研究、总结,得出以下经验,供借鉴。     

Deep‐water ascidians from the North Atlantic (RV Academic Keldysh,cruise 46 and 49)

Ascidians from two locations in the North Atlantic are discussed. Predominantly small specimens of five known species were taken by Sigsbi trawl in the vicinity of the wreck of the Titanic (the region referred to as the Titanic location), and two large specimens of a Corynascidia species were taken by manned submersible MIR‐2 on the mid‐Atlantic Ridge (the Charlie Gibbs Fracture Zone). Definitions of the species are reviewed and their relationships and intraspecific variations are discussed and revised.     

XV.—Descriptions of three new freshwater fishes from China

The North American members of the eulophid subfamily Tetrastichinae are reviewed in light of systematic advances which have occurred in other geographic realms. Forty-two genera are recognized as valid, with the largest of these, Aprostocetus, having four subgenera in the study area. Thirteen new genera are described: Apterastichus, Careostrix, Chytrolestes, Comastichus, Cucarastichus, Dapsilothrix, Eriastichus, Exalarius, Exastichus, Hadrotrichodes, Mesofrons, Oxypracetus, Styotrichia; the new subgenus Quercastichus is described in the genus Aprostocetus. Five new generic synonymies are made. With Aprostocetus Westwood, 1833: Exurus Philippi, 1873, Omphalomopsis Girault, 1917, Paromphaloidomyiia Girault, 1917, and Prothymus Girault, 1917. With Pentastichus Ashmead, 1894: Hypertetrastichus Moser, 1965. Six previously described genera are newly recorded from North America: Aceratoneuromyia, Anaprostocetus, Henryana, Kocourekia, Lisseurytomella and Pentastichus. Two hundred and twelve species of North American Tetrastichinae are currently recognized as valid. Eighty new combinations are proposed from North America, and three from the Neotropical Region. The majority of these species are being moved from the genus Tetrastichus, which had previously held most of the North American Tetrastichinae species. Eighteen new species are described: Aprostocetus (Quercastichus) burksi, Apterastichus oculatus, Careostrix yoshimotoi, Chytrolestes alibaba, Comastichus zopheros, Cucarastichus texanus, Dapsilothrix jeanae, Eriastichus cigdemae, E. masneri, E. nakos, Exalarius huachucensis, Exastichus odontos, Hadrotrichodes waukheon, Kostjukovius grahami, Mesofrons villosus, Oxypracetus opacus, Styotrichia bicolor, S. quadrata. One new specific synonymy is made. With Aprostocetus (Quercastichus) pattersonae (Fullaway, 1912): Tetrastichus spilopteris Burks, 1943. A lectotype is designated for Tetrastichus pattersonae Fullaway. Aprostocetus (Ootetrastichus) mymaridis (Girault) is removed from synonymy with Tetrastichus polynemae Ashmead and considered as valid. Twelve previously described species are newly recorded from North America: Aceratoneuromyia fimbriata Graham, Anaprostocetus acuminatus (Ratzeburg), Aprostocetus antiguensis (Crawford), A. leucone (Walker), A. pygmaeus (Zetterstedt), A. strobilanae (Ratzeburg), A. longicauda (Thomson), A. terebrans (Erdös), Henryana magnifica Yoshimoto, Kocourekia debilis (Ratzeburg), Lisseurytomella flava (Ashmead), Tamarixia leucaenae Bou?ek.     

Description of a new species of Armandia (Polychaeta: Opheliidae) from western Kyushu,Japan, with character variations

Armandia amakusaensis sp. nov. (Polychaeta: Opheliidae) is described from an intertidal sandflat in western Kyushu, Japan. The holotype measures 13.14 mm in total body length, and has 32 setigers, with branchiae on setigers 2–31. Eleven pairs of lateral eyes are present on setigers 7–17. The anal funnel opens dorsally, fringed with 11 papillae, its length being slightly shorter than the length of the last three setigers. A long unpaired cirrus originates mid-ventrally from the inside of the anal funnel. Variation in these diagnostic characters is described. The new species is most similar to A. leptocirris (Grube, 1878) and A. intermedia Fauvel, 1902. However, it is distinguished from A. leptocirris in the distribution patterns of the branchiae and the lateral eyes, and from A. intermedia in the distribution pattern of the lateral eyes, the ratio of anal funnel length to total body length, and the number of anal-funnel papillae.     

A new genus and six new species of the Parabathynellidae (Bathynellacea,Syncarida) from the Kimberley region,Western Australia

Six new species of a new genus of the Parabathynellidae are described from the Kimberley Region, Western Australia. The erection of the new genus, Kimberleybathynella gen. nov., is based on the two‐segmented antenna, the partial fusion of the second and third segments of the maxilla, and the setal condition of the uropodal exopodite, where the outer seta is longer than the inner one. The one‐segmented exopodite of thoracopods I–VII and hemispherical form of male thoracopod VIII suggest the close relationship of Kimberleybathynella to the genus Atopobathynella.     

On the systematics,distribution and conservation status of Ichthyophis longicephalus Pillai, 1986 (Amphibia: Gymnophiona: Ichthyophiidae)

The caecilian Ichthyophis longicephalus was described in 1986 based on a single specimen. Only one specimen has been referred subsequently to this species, and the validity of that referral has been questioned. Seven specimens discovered in 2009–2010 at two new localities and two specimens collected in 1990 from a third locality are referred here to I. longicephalus. These specimens are described and compared with the poorly preserved holotype. Mitochondrial DNA data are consistent with the interpretation that the new specimens represent a single species distinct from (and most closely related to I. tricolor among) sampled congeners. The previously referred specimen, from c. 320 km south of the type locality, is not I. longicephalus and probably represents an undescribed species. The “rediscovery” of I. longicephalus in forests and disturbed habitats indicates that the species probably could be transferred from the Data Deficient to the Least Concern category of the IUCN Red List.     

Calcareous nannofossil bioevents and microtektite stratigraphy in the Western Philippine Sea during the Quaternary

Two sediment cores, MD06-3050 and MD06-3047, were analyzed to study the Quaternary calcareous nannofossil and microtektite records. We dated bioevents and the microtektite impact event by calibrating with oxygen isotope stratigraphy. Seven calcareous nannofossil bioevents were identified over the past 2.36 Ma including the last appearance of data for Discoaster brouweri, Calcidiscus macintyrei, large Gephyrocapsa and Pseudoemiliania lacunosa, the first appearance of data for large Gephyrocapsa and Emiliania huxleyi, and the abrupt increase in the abundance of Gephyrocapsa caribbeanica. In addition, we fortunately observed that Australasian microtektites were distributed in core MD06-3050 from 1340 to 1374 cm.     

辜鸿铭、杜亚泉、梁漱溟中西文化观之比较

二十世纪初，中国经历了前所未有的震荡与激变，强势的西方文化把整个中国都卷入到“西化”的浪潮中。面对民族和文化的双重危机，以辜鸿铭、杜亚泉、梁漱溟为代表的文化保守主义，高举中国传统文化，以复兴传统文化来振兴民族精神。他们与新文化派展开了一系列的论战。中西文化之争便成了世纪之初我们民族精神生命层面的主流。
