Two new species of the genusTinocladia Kylin (1940)T. eudesmoides Ding et Lu sp. nov. andTinocladia zhangii Ding et Lu sp. nov., are described.T. eudesmoides is mainly characterized by its longitudinally and transversely produced sub-cortical filaments from the medulla, its short uniseriate assimilating filaments, usually composed of 6–10 cells with slightly swollen and narrow ultimate cells, and its unilocular sporangia (60–115)×55–70μm, variable in size.T. zhangii is mainly characterized by its very solid frond, not rip apart by hands, its evident longer primary branches, its short and slender secondary branches, with very evident sub-cortical layer, and filaments divided repeatedly, and its large and small unilocular sporangia, with the latter borne on an evidently swollen pedicel.

Design formulations for supplemental viscous dampers to highway bridges     

Jenn‐Shin Hwang  Yi‐Shane Tseng 《地震工程与结构动力学》2005,34(13):1627-1642

Design formulas for supplemental viscous dampers to building structures are readily available in FEMA provisions and MCEER research reports. However, for the design of supplemental viscous dampers corresponding to a desired system damping ratio of highway bridges, there exist, if any, few design guidelines. This is particularly true if the bridge components such as elastomeric bearings, piers and abutment possess different damping ratios, stiffnesses, and lumped masses. In this paper, the design formulas for supplemental viscous dampers to highway bridges have been derived based on the concept of ‘composite damping ratio’. The design formulas can be used to determine the damping coefficients of the dampers corresponding to a desired system damping ratio of the bridge in which different component damping ratios may be assumed for the elastomeric bearings, piers and abutments. The proposed design formulas are numerically validated by comparing the seismic responses of a three‐span bridge equipped with viscous dampers with those of the same bridge without viscous dampers but with an assigned inherent system damping ratio equal to the target system damping ratio.

中国马尾藻属的研究　Ⅳ.具腺系的两个新种

──线形马尾藻和钦州马尾藻     

曾呈奎  陆保仁 《海洋与湖沼》1994,25(4):368-371

对于中国马尾藻属，真马尾藻亚属滑托组Malacocarpicae（J.Ag．）Abbott，TsengetLu．总状托序亚组suhectionRacemosae,具腺系SeriesGlandulariae的种类进行了系统的研究。结果表明，中国共有具腺系3个种，除棒托马尾藻前人已经报道外，本文建立了两个新种，它们是：1．线形马尾藻，模式标本于1955年5月7日来自广东省硇洲岛，模式标本号为AST55－2259；2．钦州马尾藻，模式标本于1955年5月7日采自广西钦州湾龙门镇，模式标本号为AST55－1987。两者的模式标本均保存于中国科学院海洋研究所藻类标本室。  相似文献   

中国异枝软骨凹顶藻Chondrophycus intermedius (Yamada) Garbary et Harper的形态及解剖学     

丁兰平  黄冰心  曾呈奎 《海洋科学集刊》2006,47(47):182-189

异枝凹顶藻Laurencia intermedia Yamada广泛地分布于东亚西太平洋沿岸的中国、朝鲜半岛(Nam et al. , 1984)及日本(Yoshida et al. , 1998)。在东南亚的菲律宾(Silva et al., 1987)，太平洋的斐济岛(NYeurt et al., 1996)，东非、印度次大陆及印度洋的斯里兰卡、肯尼亚、坦桑尼亚及Réunion (Silva et al., 1996)，以及西非的利比里亚、象牙海岸及加纳(Law son et al., 1987)等地均有报道。 Howe(1934)最早报道了中国的异枝凹顶藻。1962年，曾呈奎、张峻甫在“黄海西部沿岸海藻区系的温度性质”一文中也提到了该藻。1983年, 曾呈奎等在《Common seaweeds of China》中报道了黄海沿岸的异枝凹顶藻。1983年, 杭金欣等在《浙江海藻原色图谱》报道了浙江嵊山、渔山和南凫岛的异枝凹顶藻。1988年，张峻甫等也再次对该藻进行了报道。2000年，黄淑芳报道了台湾的异枝凹顶藻。  相似文献

In our phycological trips to the Xisha Islands,Guangdong Province,South ChinaSea in 1976 and 1980,two interesting brown algae had attracted our special attention.Oneof them was a Hydroclathrus,evidently more delicate and slender than H.clathratus com-monly met with in the South China Sea region.The other was a Turbinaria,characterizedby especially small leaves.Comparative studies of the two algae with other known speciesof the two genera concerned showed sufficient differences to warrant their statuses as un-  相似文献
