Species Diversity and Abundance Distribution of Pelagic Siphonophores in Nan Wan Bay of Taiwan, China, in Late Autumn and Early Winter

Zooplankton surveys were carried out on November 2-3 and December 8-10, 2001 at 12 stations in the Nan Wan Bay of Taiwan, China. Altogether 92 quantitative zooplankton samples were collected from subsurface water and bottom water layers with two conical plankton nets （180 cm in length, 45 cm in opening diameter, 333μm and 200 larn in mesh size）. A total of 31 species of Siphonophores were identified, among them 7 species are new records in the waters around Taiwan Island, of which Rocacea cymbiformis is a new record in China. Dominated by Chelophyes appendiculata, Bassia bassensis, Diphyes bojani, Diphyes dispar, Abylopsis eschscholtzi and Chelophyes contorta, these species accounted for over 76 % and 63 % of the total abundance in November and December. The species number and Siphonophores abundance in December （25 species, 1.99 inds/m3） were more than those in November （19 species, 0.438 inds/m3）, and they were more in the surface water layer than in the bottom layer at most sampling stations. In early winter, the offshore high salinity water mass was a main factor influencing the distribution. The sampling efficiency for two plankton nets is discussed and the seasonal variation of species number and abundance in the Nan Wan Bay is compared with that in the neighboring waters.

石家庄市污染日特征及其天气背景分析

对石家庄市2002年1月到2004年12月空气质量达到中度及以上典型污染日进行了统计分析,得出典型污染日的分布特点、对应的气象要素特征及3种天气型。结果表明:典型污染日多出现在采暖季节,出现时间具有相对连续性;污染日分为沙尘和非沙尘两类,气象要素特征前者表现为风速大、湿度小、多正变压等锋后特征;后者则表现为地面风小、湿度高、多逆温层、大里查逊数等稳定大气层结,这些均为锋前特征;还侧重指出由于石家庄的特殊地形作用,高压前部型是石家庄重污染出现几率最多的天气类型。并由此提炼出中度以上污染日的预报要点,可供空气质量预报业务参考。     

福州峨嵋叶蜡石矿区围岩蚀变特征及成矿作用初步探讨

The Emei pyrophyllite ore district is localized in the middle part of eastern Fujian volcanic eruptive belt, within the Mesozoic fault mobile zone along the coast region of Fujian and Zhejiang. Upper Jurassic (J3n) Nan Yan Formation, which is composed mainly of rhyolitic erystalclastic tuff-lava, rhyolite and rhyolitic crystal tuff, is widely distributed throughout this region. Pyrophyllite and alumstone ore bodies occur principally in the rhyolitic crystal tuff and volcanic breccia-bearing tuff in the IV litbofaeics of the Nan Yan Formation. As a result of hydrotbermal metasomatism closely related to volcanic activities, pyrophyllitization, silicifieation and alunitization, empholitization, pyritization, and etc. are extensively developed, causing a systematic migration, enrichment and resetting of the constituents in the tuffs.     

根据因果岸三维地震资料研究地裂缝形成机理

塌隐地裂缝，改变了地层的几何结构，破坏了三维地震反射层的连续性，出现了反射波同相轴错断、反射层产状变化、反射波能量转换、反射波增多或减少等特征。据此利用石塘湾因果岸三维地震资料对其地裂缝地质灾害形成进行了研究。通过对实际资料的分析，指出本区地裂缝类型为张跌型，并以较多的资料翔实地说明了诱发本区地裂地质灾害不可分割的五个因素，从而为治理地裂缝地质灾害提供了丰富的地质资料和治理方向。     

多旋翼微型无人机气象探测适用性分析

本文通过多种试验对多旋翼无人机搭载微型气象探测设备进行低空温湿度探测和数据传输进行了适用性分析。结果表明,采用433 MHz无线透传的数据通讯方式数据传输稳定性较好,选用的微型气象探测设备温湿度传感器通过了实验室计量检定,与百叶箱温湿度的对比观测中二者一致性较好;无人机在单纯悬停过程中,温湿度观测与对比观测设备误差较小,相关性较好;在低空连续飞行过程中,温湿度观测结果与探空仪观测结果具有较好的一致性(温度平均绝对误差0.84℃,相对湿度平均绝对误差4%),但存在温湿度小脉动变化无法捕捉的情况,可能与设备温湿度响应时间、通风防辐射罩结果、飞行速度等有关。
