武功山国家森林公园的自然生态化规划设计实践

森林是重要的自然资源，在开发方式上应十分慎重。以自然生态化规划设计思想作为指导思想，进行了武功山国家森林公园的规划和设计，进行了森林公园可持续规划设计的探索。     

三种草坪草净光合速率和蒸腾速率的日变化特点研究

研究了在晴天的条件下，假俭草、细叶结缕草和地毯草净光合速率和蒸腾整编的日变化特点。结果表明：（1）假俭草和细叶绍缕草的净光合速率的日变化曲线均为双峰型，而地毯草为三峰型，3种草出现峰值的时间不同，均有明显的“午睡”现象，日平均净光全速率的大小顺序为俭草＞地毯草＞细叶结缕草；（2）假俭草和细叶结缕草的蒸腾速率的日变化曲线均为双峰型,而地毯草为单峰型，3种草出现峰值的时间有所判差别，“午睡”现象均不明显，日平均蒸腾速率的大小顺序为细叶绍缕草＞地毯草＞假俭草；（3）不同生态因子与3种草坪草净光合速率、蒸腾速率的相关程度均不相等。同种态因子与不同草坪草的净光合速率、蒸腾速率的相关程度也不一样。     

泡沫比例混合器在液下喷射灭火系统中的应用

提出了环泵泡沫比例混合器和泡沫压力比例混合器在相应灭火系统中的应用、安装和操作中应注意的问题，对两种泡沫比例混合器组成的系统进行了对比，认为环泵比例混合泡沫灭火系统采用正压进水，可以克服负压进水方式存在的缺陷，比较适合油库火灾的扑救；压力比例混合泡沫灭火系统灵活性、匹配性较差，适用于泡沫混合液流量相对不变的火灾扑救。

The immunohistochemical detection of Mycoplasma bovis and bovine viral diarrhea virus in tissues of feedlot cattle with chronic, unresponsive respiratory disease and/or arthritis.

The purpose of this study was to determine the frequency of selected pathogens in the tissues of a group of feedlot cattle with chronic disease (most often respiratory disease and/or arthritis). Samples of lung and joint tissues from 49 feedlot animals that had failed to respond to antibiotic therapy were tested by immunohistochemical staining for the antigens of Mycoplasma bovis, Haemophilus somnus, Pasteurella (Mannheimia) hemolytica, and bovine viral diarrhea virus (BVDV). Mycoplasma bovis was demonstrated in over 80% of cases, including in 45% of joints and 71% of lungs tested. Mycoplasma bovis was the only bacterial pathogen identified in the joints. Haemophilus somnus and Pasteurella (Mannheimia) haemolytica were found in 14% and 23% of cases, respectively, and were confined to the lungs in all instances. Infection with BVDV was demonstrated in over 40% of cases. Mycoplasma bovis and BVDV were the most common pathogens persisting in the tissues of these animals that had failed to respond to antibiotic therapy.     

猫鼻气管炎病毒、怀状病毒、泛白细胞减少症病毒的分离及其其形态学观察

根据病毒的理化特性，从猫三联活疫苗中分离出猫鼻气管炎、猫西洋太和猫泛白细胞减少症病毒；筛选出每种病毒敏感的细胞，并将该3种病毒分别分别在其中传代与扩增；通过电镜观察此3种病毒的形态学特征及其在宿主细胞内增殖部位、分布情况等，并以此对猫3种病毒进行了初步鉴定。     

关于我国海水网箱养鱼发展现状与危机分析及可持续发展的探讨

我国海水网箱养鱼发展现状是以个体联合体生产经营为主体的低技术水平的数量规模化，众多传统港湾已形成了大范围的严重超负荷养殖状态，其对环境巨大的污染力引发鱼病猖獗和频受赤潮侵袭，已面临严峻的养殖环境危机。本文综合分析了我国海水网箱养鱼的发展现状与负面效应及其现状危机，并初步进行了危机根源和可持续发展的讨论分析。     

Enhancement of sulfide auto-oxidation by metal ion in artificial seawater and a seawater which is a possible source of aoshio

SUMMARY: Aoshio is hypoxic milky blue-green seawater observed in some eutrophic bays. Previous studies have shown that colloidal sulfur causes the coloration and that the source of aoshio water is attributed to coastal anoxic bottom water. Occurrences of aoshio have been reported in limited areas of coastal seawater, although hypoxic transparent water seems rather universal. Promotion in auto-oxidation of sulfide by metal ions in seawater was investigated to explain the occurrences of aoshio. Artificial seawater containing 10 μM metal ion was assayed for the sulfide oxidation rate. The velocity constant which represents the oxidation rate within the initial 30 min and the amount of reacted sulfide in 2 h were determined by oxygen monitoring and sulfide quantification, respectively. Fe²⁺ and Cu²⁺ enhanced the initial 30 min reaction. Fe²⁺, Fe³⁺ and Ni²⁺ increased the amount of reacted sulfide in 2 h, forming whitish turbid water. Seawater from a suspected source of aoshio water was also assayed for the auto-oxidation rate of sulfide. The oxidation rate in water from 12 m depth was 13–19 times higher than the artificial seawater without an addition of heavy metal ions. More than 15% of the oxidation rate in 12 m deep seawater was explained by dissolved iron in the seawater.     

比格犬人工感染埃立克体病的临床研究

为了表述比格犬感染埃立克体（Ehrlichia)后的临床表现，用已确证为Ｅ．platys和Ｅ．canis混合感染的犬血对５条比格犬进行了人工感染，并对临床和血液学变化进行了观察。埃立克体病的潜伏期为６－２９天，其后的临床表现为急性发热、眼结膜苍白、厌食、精神沉郁、体重严重减轻、腹泻带血、多处有淤血斑点出现、６－４５天内全部死亡。血液学变化显示血红蛋白和白细胞明显减少（Ｐ＜０．０１，Ｐ＜０．０５）。由此可见，比格犬对２种埃立克体（Ｅ.canis和Ｅ．platys）混合感染的性很高，严重的临床表现与美国学者普遍认为的亚临床状态相左，这可能是中国Ｇzh981株（Ｅ．platys)和Ｇzh982株（Ｅ．casnis)与国外株在毒力上的差异所致。
