异面隔热保温块

提出了采用涂刷涂料、粘贴薄膜、铺瓷砖等方法,使多面体的2个或2个以上表面的热工性能（特别是对太阳辐射热的吸收系数）不同,就可制得“异面隔热保温块”.说明了在不同的季节,改变“异面隔热保温块”的放置方式,可以取得保温或隔热的效果.     

长期冻存对毛冠鹿（Elaphodus cephalophus）肺细胞株的细胞遗传学效应

对液氮冻存19年的雄性毛冠鹿的胚肺细胞株进行复苏培养并对其核型进行观察,结果发现F21代时细胞株的核型已发生了变化,出现了一对大的末端着丝染色体。C带显示这一对染色体异染色质丰富,与已存在的相关染色体同源。这一核型不同于已报道的核型,是一种新的核型。     

关于赣傩文化研究视野的综述

赣傩文化调查始于20世纪50年代,而其进入学术研究领域则肇始于90年代。而毛礼镁、余大喜等学者是赣傩文化研究的先期者,他们从不同的视野对赣傩文化进行了研究,主要包括赣傩的起源、傩面具、傩神考辨、傩义、傩功能及傩文化保护等视野。     

巨人南瓜标本保存液的研究

为了研究巨人南瓜标本的保存液,通过测定吸光度、硬度和pH等指标,在筛选基本保存液和护色剂的基础上,确定了巨人南瓜标本的最佳保存液.结果表明:巨人南瓜浸泡液的最大吸收波长为443nm,三乙醇胺∶福尔马林∶水=2∶7∶91配制的溶液能较好地保持巨人南瓜的硬度和颜色;添加0.3%的苯甲酸钠能提高保存液的护色作用,而氯化锌对巨人南瓜颜色具有破坏作用,该保存液可用于巨人南瓜标本的长期(至少12个月)保存.

Exceptionally preserved brachiopods from the Chengjiang Lagerst（a｜¨）tte（Yunnan,China）：Perspectives on the Cambrian explosion of metazoans

The Cambrian explosion was coined to describe the geologically sudden appearance of numerous bilaterian body plans（Phyla）around the Ediacaran-Cambrian transition,around 565-520million years ago.Many explanations and conjectures have been postulated in order to explain the pattern and duration of this explosive radiation of many different phyla of early metazoans.Here,we focus on the evolution of a phylum of marine suspension-feeding animals—the brachiopods,as exemplified by the exceptionally preserved taxa from the celebrated Chengjiang Konservat Lagerst（a｜¨）tte（Yunnan,China）.The abundant soft-bodied preservation at these fossil quarries gives us the only firm insights into what brachiopods looked like and how they functioned and lived when they first appeared on the Earth.Studies of Chengjiang brachiopods demonstrate that the early animals developed a remarkably varied organization of tissues and organs shortly after the onset of Cambrian explosion.In the marine suspension-feeding brachiopods,most importantly the tentaculate feeding structure of early brachiopods is already differentiated into two shapes of lophophore,anteriorly coiled（spiralled）and posteriorly arching tentacle crowns and the unique latter type was previously not documented from fossil and living brachiopods.Also unlike any known Recent brachiopod,all the known Cambrian brachiopods from Chengjiang have an open digestive tract that was disposed either as a Ushaped gut in linguliform and stem group brachiopods,or straight gut with a posterior anus in some calcareous-shelled stocks.Moreover,in contrast toliving lingulids,all the Cambrian brachiopods have an epibenthic lifestyle either cemented by a ventral valve or attached by variable pedicles to establish complex ecological community encompassing primary tierers and variable secondary tierers.It is therefore assumed that brachiopods were the first benthic metazoan that achieved their success in ecological stratification and tiering complexity by late Atdabanian.The setae are also important for the brachiopod suspension-feeding life style,and in the Chengjiang braehiopods they include two types cilia-like and spine-like setae.The mantle canals of different braehiopod species are also distinctly variable in arrangement,mainly disposed in pinnate,baeulate and peripheral conditions.Of these,the peripheral disposition of mantle canals is for the first time proposed here so as to differentiate from the bifurcate condition in recent lingulids in that the former is devoid of posteriorly extending main trunks of sinus,but possesses a diverging dorsal vascula media in dichotomy.

保护古都与建设新北京要齐抓并举

北京既是著名的历史文化名城，又是国际化大都市，这种特殊的城市功能要求保护古与建设新北京要齐抓并举。在建设新北京中强调保护古都风貌，保护文物古迹，会带来难度，会减少投资者的经济回报率。因此，近些年来在北京城市改造中，国务院批复的具有法律效力的《北京城市总体规划》中设定的建设高度被突破了，城市基础色调被搅乱了，城市建筑风格被改变了，如果在今后的城市建设中，单纯算经济帐，在不久的将来，反映老北京内涵的古
