养殖大菱鲆血细胞形态和相关生理指标的测定

研究了大菱鲆血细胞的类型、形态以及血液生理学指标.大菱鲆的血细胞可区分为红细胞、淋巴细胞、单核细胞、嗜中性粒细胞和血栓细胞5种类型,没有发现嗜酸性粒细胞和嗜碱性粒细胞.在白细胞中,血栓细胞和小淋巴细胞较小,嗜中性粒细胞和单核细胞较大.血细胞计数测得红细胞密度为(2.73±0.22)×106个/mm3,白细胞密度为(1.79±0.25)×104个/mm3.淋巴细胞、单核细胞、嗜中性粒细胞和血栓细胞在白细胞中所占的比例分别为:(24.72±6.26)%,(5.26±1.95)%,(13.45±3.31)%和(56.60±9.52)%.血红蛋白含量为(6.63±0.58)g/100mL,红细胞渗透脆性为(0.38±0.04)%NaCl,凝血时间为(80±12)s.

落葵果实中总黄酮提取条件的研究

采用超声波提取法,通过正交实验确定从落葵果实中提取总黄酮的最佳工艺条件,并用比色法测定提取物中总黄酮的含量.结果表明,最佳条件是以体积分数为70%的乙醇为提取剂、料液比为1：20、提取时间为35min.在此条件下,落葵果实总黄酮提取量为5.3 mg蛐g.     

民俗化的隐喻概念对二语隐喻习得的影响

掌握隐喻的认知概念是培养隐喻能力的重要一环 ,而隐喻的认知概念错综复杂 ,大多为约定俗成的民俗化概念 ,没有详细周全的明文规则可循 ,这一特性对学习二语隐喻所造成的障碍至今还未受到足够的重视。本文从中国学生的一个英文句子入手 ,剖析了误用习语的原因 ,指出误用是由误解引发的 ,而误解的根源是学生过于依赖词典的解释。文章表明单靠词典的释义无助于清晰地了解民俗化的隐喻概念     

哲学分析的典范--奥斯汀驳感觉材料理论

奥斯汀对感觉材料理论的驳斥是他运用语言探究方法检查传统哲学论证的一个典型范例.他认为“我们是感知物质事物还是感知感觉材料?”这个传统知觉问题本身似是而非,而建基在“依据错觉的论证”之上的感觉材料理论则包含大量迷惑人的谬误和各种隐藏着的动机.艾耶尔所表述的论证包含许多语词上的误用或滥用以及诸多对知觉事实的错误概括,其真实动机就是要把现实世界观念化或虚幻化.奥斯汀对感觉材料理论的驳斥并非仅具有否定意义,在批驳感觉材料理论过程中,他还在知觉对象、知觉方式、知觉描述、经验性质等方面提出正面的观点.他的观点至少校正了我们思考知觉问题的框架和方向.     

诸子“务为治”与《吕氏春秋》杂家特色的形成

《吕氏春秋》杂而成家不仅在于兼容并蓄,而且有系统的思想体系即以政治理论为主旨。司马谈《论六家要旨》谓先秦诸子各家皆＂务为治＂,深刻指出了其中＂知人＂、＂为治＂的参政目的。正因为诸子各家皆＂务为治＂才促进了《吕氏春秋》杂家特色的形成,同时该书杂而成家及突出的政治理论思想,也正是诸子各家因＂务为治＂而融通发展的集中表现。

The Transport System and Society’s Metabolism in the UK

This paper analyses the interrelation between the transport system and measures of resource consumption such as material and energy consumption over a 60-year period (1937–1997) in the UK. Non-motorized transport and time consumption for mobility are estimated in addition to conventional measures of transport. During the period analyzed, the UK population grew by 20% while transport of goods and persons increased more than threefold and material and energy consumption almost doubled. The transport intensity of domestic material input (DMI) doubled to 300 ton-kilometers (tkm) per ton of DMI while the transport intensity of domestic energy consumption (DEC) doubled to 20 tkm per gigajoule (GJ) of DEC. Thus, while the material and energy intensity of GDP declined significantly, a well-established trend in many advanced countries, the transport intensity of materials and energy consumption rose. These findings suggest a close link between transport, economic development, and long-term structural transformations. In the case of personal transport, a rebound effect was also observed: whereas the average speed of transport has greatly increased, the average number of hours per day devoted to personal transport has not declined.     

UNCERTAIN DEMAND,CONSUMER LOSS AVERSION,AND FLAT‐RATE TARIFFS

We consider a model of firm pricing and consumer choice, where consumers are loss averse and uncertain about their future demand. Possibly, consumers in our model prefer a flat rate to a measured tariff, even though this choice does not minimize their expected billing amount—a behavior in line with ample empirical evidence. We solve for the profit‐maximizing two‐part tariff, which is a flat rate if (a) marginal costs are not too high, (b) loss aversion is intense, and (c) there are strong variations in demand. Moreover, we analyze the optimal nonlinear tariff. This tariff has a large flat part when a flat rate is optimal among the class of two‐part tariffs.
