论希尔伯特对数理经济学公理化进程的一个贡献

分析了希尔伯特（David Hibert）在哥廷根的一份授课笔记的具体历史背景,同时将二十世纪初经济学和心理学的密切关系联系起来进行分析研究,推断出希尔伯特对二十世纪数理经济学的公理化进程所起的作用。     

Saving the Strong Programme: a critique of Stephen Kemp’s recent paper

In this paper I intend to discuss some of the views put forward by Stephen Kemp in his recent critique of the Strong Program (Kemp, 2005). In particular I will try to defend David Bloor’s SSK against the charge of weak idealism brought up by Stephen Kemp in his paper. The widely held accusation, namely, according to which the social constructionist approach to scientific knowledge is strongly idealist, is already rejected by Kemp himself. He argues, however that Bloor’s attempts to divert the charge of idealism from the Strong Programme were not successful with respect to the kind of idealism that Kemp calls ‘weak idealism’, that is, treating scientific discourse as free-floating and unrelated to the world of things. I intend to argue that Kemp’s charges are unfounded when levelled at Bloor’s views on meaning and reference. Kemp deals with two issues of the Bloorian program: with the social constructionist approach to concepts as self-referential social institutions, and with the actor/analyst distinction introduced by the Strong Programmers. I will focus only on the first issue in my paper.     

A specimen of Tirumala hamata hamata (Macleay, 1826) (Lepidoptera: Danainae) from Captain Cook’s first voyage

On 29 May 1770 Joseph Banks described a spectacular swarming of ‘milions’ [sic] ‘of one sort’ of butterfly at Thirsty Sound, near what is now Rockhampton, Queensland, comparing it to a species from China that had been named by Linnaeus. Discovery of what appears to be an Endeavour voyage specimen of this Australian butterfly in the Hunterian Zoology Museum, Glasgow, allows us to confirm its long-suspected identity as Tirumala hamata hamata (Macleay) – a species unnamed and unknown at the time of Cook’s first voyage. Investigations into several collections that include eighteenth-century Australian Lepidoptera and associated literature have not positively identified any further specimens taken from the swarm, although a pair in the Oxford University Museum of Natural History could be from the same source. Taxonomic confusion due to mimicry, convergence and/or non-divergence affecting blue tiger patterned butterflies is most likely the principal reason such a specimen has previously gone undetected.     

林蛙输卵管总RNA提取方法的优化及RT-PCR验证

分别使用改良的十六烷基三甲基溴化铵(CTAB)法、 TRIzol法和RNAiso Plus法对林蛙的输卵管组织进行总RNA提取, 考察不同方法对总RNA提取量的影响. 结果表明: 利用改良的RNAiso Plus法并经进一步纯化, 获得总RNA的A₂₆₀/A_280平均值为1.96, 平均得率为56.1 μg/g; 通过反式多聚酶链式反应（RT-PCR）获得了林蛙-GAPDH基因和EF-1-α-基因的部分序列.     

南移养殖中国林蛙繁殖习性研究

对在半人工生态系统中南移至浙江省新昌县的中国林蛙的冬眠、抱对、产卵、孵化、取食等生物学特性，及一些影响其生长繁殖的因素进行了分析，认为中国林蛙的南移养殖将更有利于其的生长繁殖．     

东北小鲵和东方蝾螈血细胞形态学参数研究

对东北小鲵和东方蝾螈 2种动物的血细胞进行显微观察 ,测定细胞的大小和白细胞数量比例 .结果表明 :2种动物的红细胞和白细胞比爬行类大 ;白细胞的数量比例有一定的种的特征 .其中淋巴细胞比例最高 ,而嗜酸性粒细胞和嗜碱性粒细胞分别在东北小鲵和东方蝾螈中比例极小     

哈士蟆和青蛙输卵管几种主要成分分析测定研究

分析测定了哈士蟆和青蛙输卵管的蛋白、脂溶性维生素、脂肪酸、微量元素及重金属的成分和含量.结果表明:哈士蟆与青蛙输卵管蛋白含量较高,分别为72.8%和73.8%;哈士蟆输卵管维生素A和维生素D的含量为青蛙输卵管的1.3和1.6倍,哈士蟆输卵管维生素E的含量为4.09μg/g,在青蛙输卵管中未测出维生素E;哈士蟆与青蛙输卵管脂类物质的含量基本上一致,约为6%,其中不饱和脂肪酸含量分别占其脂肪酸的77.26%和64.67%;哈士蟆与青蛙输卵管均含有人体营养必需的常用微量元素,但青蛙输卵管中重金属Pb、Hg含量超标.     

镉对中国林蛙外周血细胞微核及核异常的诱导效应

用不同剂量Cd2^＋注射林蛙，5d后取血制片，光镜观察，探讨了不同剂量Cd2^＋对中国林蛙红细胞形成微核及核异常的影响．结果表明，Cd2^＋可诱导红细胞产生微核和核异常．Cd2^＋剂量高于0．2mg／kg作用5d后，对林蛙血细胞具有明显的毒性效应．Cd2^＋剂量低于0．5mg／kg范围内，微核与核异常细胞率随Cd2^＋的增加呈上升趋势；当Cd2^＋剂量高于0．5mg／kg时，微核与核异常细胞率随Cd2^＋的增加而下降．     

镉对中国林蛙肾组织结构的毒性效应

采用不同剂量的Cd^2＋溶液对中国林蛙（Rana chensinensis）成体隔日皮下注射染毒，光镜下观察肾组织的显微结构变化．结果表明，在以每次剂量为0．1mg／kg的Cd^2＋溶液注射20次后，肾小管上皮细胞未发生明显变化；以每次剂量为0．25mg／kgCd^2＋溶液注射20次后，以及剂量为0．5mg／kg、1mg／kg和2．5mg／kgCd^2＋溶液注射10次后，肾近曲小管上皮细胞出现不同程度的浊肿、水样变性和脂肪样变等现象；在每次剂量为6mg／kgCd^2＋溶液注射4～7次、每次剂量为12mg／kg Cd^2＋溶液注射2～4次时，近曲小管上皮出现糜烂，远曲小管上皮也有不同程度的变性，肾小球发生变形．说明两栖动物的镉染毒，随着镉剂量的增加和处理时间的延长，肾组织损伤程度加重．     

中国林蛙幼蛙性别诱导后性腺的组织学观察

对中国林蛙幼蛙性别诱导后的性腺进行了组织学观察,结果发现,诱导后雌性幼蛙性腺的组织学特征与自然分化的雌蛙幼蛙性腺组织结构没有明显差异.这些结果为中国林蛙养殖和性别诱导提供了必要的组织学证据.
