煤矿环境中人体ESD模型

在有瓦斯的煤矿环境中,井下工作人员等效于移动的孤立静电导体,人体静电比井下器材静电更具有隐蔽性、偶发性、危险性.本文通过实验确定能代表煤矿特殊环境中的人体电容、人体电阻,建立煤矿环境中的人体ESD物理模型,为制定煤矿人体静电安全标准提供实验依据.     

Colonial ascidians from the Foveaux Strait region of New Zealand

Colonial ascidians collected from wharf piles and natural substrata from Bluff Harbour and Stewart Island in the South Island of New Zealand are described in this paper. Two species, Lissoclinum violaceum sp. nov. and Didemnum marineae sp. nov. are new to science and described for the first time. The ascidian fauna in this region is a mixed assemblage of southern species, species with a New Zealand-wide distribution, and two species with trans-Tasman affinities.

原子第二宇宙速度与电离能普遍公式的推导、实验验证和理论预言

提出了“原子第二宇宙速度”这一新概念,并根据此概念推导出了单电子原子和离子的原子第二宇宙速度和电离能的普遍公式。根据这些公式计算出了100余种单电子原子和离子电离能的具体数值,计算数据与实验数据符合得很好,从而使这一新的理论和计算获得了成功。因现今实验技术的局限性,有些单电子离子的电离能实验值尚未被科学界测出,我们的理论计算值就作为理论预言列出,已获得的成功使我们有理由相信它们将会获得实验验证。本文的概念和计算显然涉及到经典物理与量子物理的关系等原则问题,其物理本质将在后面两篇文章中论述。     

Gastrointestinal helminths from fifteen species of Litoria and Nyctimystes (Anura: Hylidae) from Papua New Guinea

Three hundred and ninety‐nine individuals representing 10 species of Litoria and five species of Nyctimystes (Hylidae), L. arfakiana, L. bibonius, L. eucnemis, L. genimaculata, L. impura, L. infrafrenata, L. modica, L. nasuta, L. thesaurensis, L. wollastoni, N. gularis, N. kubori, N. papua, N. pulcher and N. semipalmatus collected in Papua New Guinea were examined for helminths.

Five genera are described as new: Cabeza, including six species (baeostigma (§, ¦), canaliculata (§), laticeps (¦), petiolata (§), planiscapus (§), ugaldei (§)); Itahipeus, including two species (brasilicola (§, ¦), euryceps (¦)); Monterrondo, including one species (aphelosoma (§)); Sifraneurus, including one species (strigifer (§)); Xenopomphale, including one species (sulcata (§)); all above-mentioned species are described as new. Five additional genera are included: Aleuroctonus LaSalle and Schauff, with four species, one described previously: vittatus (Dozier) (§, ¦), and three described here: latiscapus (§), marki, (§, ¦) and metallicus (§); Entedononecremnus Girault, with 14 species, two described previously: krauteri Zolnerowich and Rose (§, ¦), unicus Girault (§, ¦), and 12 described here: bennetti (§, ¦), bimaculatus (§, ¦), convexus (§, ¦), crassicornis (§, ¦), depressus (§), fulgens (§), hansoni (§, ¦), imdasus (§, ¦), parfer (§, ¦), reticulatus (§), tripar (§) and unicarinatus (§); Euderomphale Girault, with two species, one described previously: flavimedia (Howard), and one described here: sulciscapus (§, ¦); Neopomphale LaSalle and Schauff, with 20 species, two described previously: aleurothrixi (Dozier) (§, ¦), quercicola (Dozier) (§, ¦), and 18 described here: azofeifai (¦), cerrobius (¦), depilis (§), dichrous (§, ¦), erecta (¦), graciliclava (§), longicornis (¦), longipilis (§, ¦), nonaequa (§, ¦), noyesi (§), pinguicornis (§, ¦), prymna (§), rubescens (§, ¦), rubii (§), silvestris (¦), transversa (§), umbonata (§, ¦), xenipennis (§); Dasyomphale LaSalle and Schauff, including one species (chilensis LaSalle and Schauff).

Lectotypes are designated for Entedononecremnus unicus Girault, Euderomphale quercicola Dozier and Gyrolasia flavimedia Howard. Key to genera and species are included.     

Notes on astogeny of some Petraliellidae (Bryozoa) from Australia

Members of the bryozoan family Petraliellidae share the capacity to develop basal rhizoids, which anchor the unilaminar, semi-repent parts of the colonies above the substratum, and enable them to overgrow other, competing sessile forms. Little is known of the larval behaviour and settlement, or the early astogeny of species. Ancestrulate colonies of the Australian Tertiary lunulitiform species Smittia biincisa are referred to the genus Riscodopa, and together with Riscodopa paucipora sp. nov. are described and compared with the Recent species R. cotyla and R. parva from New Zealand, and with R. hyalina sp. nov. from New South Wales, Australia. All the Recent species are known to develop basal rhizoids, and an early astogeny similar to that of many other small, rooted bryozoans, comprising the post-metamorphosis development of a binary complex, including rhizoid and feeding elements, is inferred for Riscodopa. Observations on living Hippopetraliella magna from Queensland suggest that both the ancestrular morphology and early astogeny show a capacity for semi-repent growth, even though they do not include rhizoid development. Larvae metamorphose without direct attachment, and the ancestrula develops elongated, partially calcified supporting processes, which raise the early stages of growth above the substratum. A similar kind of ancestrula has been found in preserved specimens of Mucropetraliella ellerii.     

Lernanthropus antofagastensis sp. nov. (Copepoda: Lernanthropidae) parasitic on Anisotremus scapularis in Chilean waters,and new records of Lernanthropus trachure (Brian, 1903)

Lernanthropus antofagastensis sp. nov., parasitic on Anisotremus scapularis, and inshore fish of Antofagasta, Chile, is described and illustrated. It resembles five other species of Lernanthropus in its dorsal plate and third leg, but can be distinguished from them by a combination of characters. L. trachuri Brian, 1903, is recorded, its male described and illustrated from specimens collected from Seriolella violacea and Trachurus murphy, taken in the same locality.     

A new species of mycophagous Rentonium (Coleoptera: Cleroidea: Trogossitidae) based on larvae and adults,and a catalogue of Rentoniinae

Adults and associated larvae of Rentonium bicolor sp. nov. are described from New Zealand (North Island) and represent the first associated larvae of the Rentoniinae. Larvae and adults were found among the fruiting bodies of Hypocrea rufa (Pers.) Fr. (Ascomycota: Hypocreaceae). The larvae are morphologically similar to a previously described and undetermined larva but differ from it by the unpaired, hook-like urogomphus, four stemmata, and the apical antennal seta subequal in length to the antenna. Potential implications for phylogeny of Cleroidea are discussed. A catalogue of the genera and species of Rentoniinae is provided, along with comments about the status of Rentonellum loebli Kolibá?.

The first instar larva of Aulacoscelis appendiculata n. sp. (Coleoptera: Chrysomelidae: Aulacoscelinae) and its value in the placement of the Aulacoscelinae

Of all of the chrysomelid subfamilies, only the larvae of the Aulacoscelinae remain undescribed. The adults and first instar larva of Aulacoscelis appendiculata sp. n., from Panama are described, as well as the eggs. Larval characters, eggs, and oviposition behaviour are used to relatethe Aulacoscelinae with other chrysomelid subfamilies, in support of what is known to date concerning adult morphology.
